Disease interactions
88 potential interactions Applies to: 64 conditions, including High Blood Pressure, Constipation, Heart Failure, Asthma, and Benign Prostatic Hyperplasia.
Acute Alcohol Intoxication
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Acute Alcohol Intoxication.
The use of opiate agonists is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of opiate agonists may be additive with those of alcohol. Severe respiratory depression and death may occur. Therapy with opiate agonists should be administered cautiously in patients who might be prone to acute alcohol intake.
Adrenal Insufficiency
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Adrenal Insufficiency.
Patients with Addison's disease may have increased risk of respiratory depression and prolonged CNS depression associated with the use of narcotic (opioid) analgesic agents. Conversely, these agents may cause or potentiate adrenal insufficiency. Therapy with opioids should be administered cautiously and initiated at reduced dosages in patients with adrenocortical insufficiency. Subsequent doses should be titrated based on individual response rather than a fixed dosing schedule.
Alcoholism
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Alcoholism.
Opiate agonists have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop after prolonged use. Abrupt cessation, reduction in dosage, or administration of an opiate antagonist such as naloxone may precipitate withdrawal symptoms. In patients who have developed tolerance to an opiate agonist, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with opiate agonists. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of opiate therapy should be undertaken gradually using a dosage-tapering schedule.
Major:
meloxicam
Meloxicam has a major potential interaction with Alcoholism.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms. NSAIDs should be used with caution in patients with history of peptic ulcer disease and/or GI bleeding, as these patients had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Caution is also advised if NSAIDs are prescribed to patients with other factors that increase risk of GI bleeding, such as: prolonged NSAID therapy; concomitant use of oral corticosteroids, antiplatelet agents (e.g., aspirin), anticoagulants, selective serotonin reuptake inhibitors; alcohol use; smoking; history of gastrointestinal surgery or anastomosis, older age; poor general health status; and advanced liver disease and/or coagulopathy. Particular vigilance is necessary when treating older adult or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.
Altered Consciousness
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Altered Consciousness.
Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration. Apnea may result from decreased respiratory drive as well as increased airway resistance, and rigidity of respiratory muscles may occur during rapid IV administration or when these agents are used in the induction of anesthesia. At therapeutic analgesic dosages, the respiratory effects are usually not clinically important except in patients with preexisting pulmonary impairment. Therapy with opiate agonists should be avoided or administered with extreme caution and initiated at reduced dosages in patients with severe CNS depression; sleep apnea; hypoxia, anoxia, or hypercapnia; upper airway obstruction; chronic pulmonary insufficiency; a limited ventilatory reserve; or other respiratory disorders. In the presence of excessive respiratory secretions, the use of opiate agonists may also be problematic because they decrease ciliary activity and reduce the cough reflex. Caution is also advised in patients who may be at increased risk for respiratory depression, such as comatose patients or those with head injury, intracranial lesions, or intracranial hypertension. Clinical monitoring of pulmonary function is recommended, and equipment for resuscitation should be immediately available if parenteral or neuraxial routes are used. Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Anemia
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Anemia.
Anemia has been reported in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs). This may be due to fluid retention, occult/gross blood loss, or an incompletely described effect on erythropoiesis. Hemoglobin or hematocrit should be monitored in patients with any signs/symptoms of anemia or blood loss, especially during long-term therapy. NSAIDs may increase risk of bleeding events; comorbid conditions (e.g., coagulation disorders; concomitant use of warfarin/other anticoagulants, antiplatelet agents, serotonin/serotonin norepinephrine reuptake inhibitors) may increase this risk, and patients with these conditions should be monitored for signs of bleeding. Therapy with NSAIDs should be administered cautiously in patients with or predisposed to anemia. Clinical monitoring of hematopoietic function may be appropriate, particularly during chronic therapy.
Arrhythmia
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Arrhythmia.
Opiate agonists have cholinergic activity. Large doses and/or rapid intravenous administration may produce bradycardia and arrhythmias via stimulation of medullary vagal nuclei. Therapy with opiate agonists should be administered cautiously in patients with a history of arrhythmias. Clinical monitoring of cardiovascular status is recommended during therapy.
Asphyxia
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Asphyxia.
Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration. Apnea may result from decreased respiratory drive as well as increased airway resistance, and rigidity of respiratory muscles may occur during rapid IV administration or when these agents are used in the induction of anesthesia. At therapeutic analgesic dosages, the respiratory effects are usually not clinically important except in patients with preexisting pulmonary impairment. Therapy with opiate agonists should be avoided or administered with extreme caution and initiated at reduced dosages in patients with severe CNS depression; sleep apnea; hypoxia, anoxia, or hypercapnia; upper airway obstruction; chronic pulmonary insufficiency; a limited ventilatory reserve; or other respiratory disorders. In the presence of excessive respiratory secretions, the use of opiate agonists may also be problematic because they decrease ciliary activity and reduce the cough reflex. Caution is also advised in patients who may be at increased risk for respiratory depression, such as comatose patients or those with head injury, intracranial lesions, or intracranial hypertension. Clinical monitoring of pulmonary function is recommended, and equipment for resuscitation should be immediately available if parenteral or neuraxial routes are used. Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Asthma
Major:
meloxicam
Meloxicam has a major potential interaction with Asthma.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in patients with history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients. A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps, severe potentially fatal bronchospasm, and/or intolerance to aspirin and other NSAIDs. Since cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, therapy with any NSAID should be avoided in patients with this form of aspirin sensitivity. NSAIDs should be used with caution in patients with preexisting asthma (without known aspirin sensitivity), and these patients should be monitored for changes in the signs and symptoms of asthma.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Asthma.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Benign Prostatic Hyperplasia
Moderate:
Demi-Cof
The phenylephrine in Demi-Cof has a moderate potential interaction with Benign Prostatic Hyperplasia.
Sympathomimetic agents may cause or worsen urinary difficulty in patients with prostate enlargement due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate.
Biliary Obstruction
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Biliary Obstruction.
Opioid agonists may cause spasm of the sphincter of Oddi, which may increase biliary tract pressure. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions and transient elevations in serum amylase. Patients with biliary tract disease (including acute pancreatitis) should be regularly evaluated for worsening symptoms. Therapy with opioids should be administered cautiously in patients with biliary tract disease, gallbladder disease, or acute pancreatitis.
Bleeding Disorder
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Bleeding Disorder.
Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Bleeding Disorder.
Anemia has been reported in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs). This may be due to fluid retention, occult/gross blood loss, or an incompletely described effect on erythropoiesis. Hemoglobin or hematocrit should be monitored in patients with any signs/symptoms of anemia or blood loss, especially during long-term therapy. NSAIDs may increase risk of bleeding events; comorbid conditions (e.g., coagulation disorders; concomitant use of warfarin/other anticoagulants, antiplatelet agents, serotonin/serotonin norepinephrine reuptake inhibitors) may increase this risk, and patients with these conditions should be monitored for signs of bleeding.

Brain Tumor
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Brain Tumor.
The hypoventilation associated with administration of opiate agonists, particularly by the intravenous route, can induce cerebral hypoxia and vasodilatation with resultant increase in intracranial pressure. Opiate agonists should not be used in patients with suspected or known head injury or increased intracranial pressure. Also, clinicians treating such patients should be aware that opiate agonists may interfere with the evaluation of CNS function, especially with respect to consciousness levels, respiratory status, and pupillary changes.
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Brain Tumor.
Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration.

Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Cardiovascular Conditions and Disorders
Major:
Demi-Cof
The phenylephrine in Demi-Cof has a major potential interaction with Cardiovascular Conditions and Disorders.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
Cerebral Vascular Disorder
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Cerebral Vascular Disorder.
The hypoventilation associated with administration of opiate agonists, particularly by the intravenous route, can induce cerebral hypoxia and vasodilatation with resultant increase in intracranial pressure.

Cerebrovascular Insufficiency
Major:
Demi-Cof
The phenylephrine in Demi-Cof has a major potential interaction with Cerebrovascular Insufficiency.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors.

These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Major:
meloxicam
Meloxicam has a major potential interaction with Cerebrovascular Insufficiency.
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Clinical trials of several cyclooxygenase-2 (COX-2) selective and nonselective NSAIDs of up to 3 years duration have supported this increased risk. It is unclear from available data if the risk for cardiovascular thrombotic events is similar for all NSAIDs. Therapy with NSAIDs should be administered cautiously in patients with a history of cardiovascular or cerebrovascular disease. Patients should be treated with the lowest effective dosage for the shortest duration necessary. Appropriate antiplatelet therapy should be administered to patients requiring cardioprotection; however, there is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious cardiovascular thrombotic events associated with NSAID use, while the risk of serious gastrointestinal events is increased. Physicians and patients should remain alert for the development of adverse cardiovascular events throughout the entire duration of therapy, even without prior cardiovascular symptoms. Patients should be advised to promptly seek medical attention if they experience symptoms of cardiovascular thrombotic events (including chest pain, shortness of breath, weakness, or slurring of speech).
NSAIDs are contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Two large clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke.
The use of NSAIDs should be avoided in patients with a recent myocardial infarction unless the benefits are expected to outweigh the risk of recurrent cardiovascular thrombotic events. If an NSAID is used in patients with a recent myocardial infarction, they should be monitored for signs of cardiac ischemia.
Coagulation Defects and Disorders
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Coagulation Defects and Disorders.
Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities.

NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
Colonic Ulceration
Major:
meloxicam
Meloxicam has a major potential interaction with Colonic Ulceration.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms. NSAIDs should be used with caution in patients with history of peptic ulcer disease and/or GI bleeding, as these patients had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Caution is also advised if NSAIDs are prescribed to patients with other factors that increase risk of GI bleeding, such as: prolonged NSAID therapy; concomitant use of oral corticosteroids, antiplatelet agents (e.g., aspirin), anticoagulants, selective serotonin reuptake inhibitors; alcohol use; smoking; history of gastrointestinal surgery or anastomosis, older age; poor general health status; and advanced liver disease and/or coagulopathy. Particular vigilance is necessary when treating older adult or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.
Constipation
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Constipation.
Narcotic (opioid) analgesic agents increase smooth muscle tone in the gastrointestinal tract and decrease peristalsis, which can lead to elevated intraluminal pressure, spasm, and constipation following prolonged use. In patients with severe or acute inflammatory bowel disease, the decrease in colonic motility may induce toxic megacolon. Therapy with opioids should be administered cautiously in patients with gastrointestinal obstruction, constipation, inflammatory bowel disease, or recent gastrointestinal tract surgery. Gastrointestinal effects appear to be the most pronounced with morphine.
COPD
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with COPD.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Dehydration
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Dehydration.
Opiate agonists can induce vasodilation and significant hypotension, particularly when given in high dosages and/or by rapid intravenous administration. Opiate analgesics cause vasodilatation that may exacerbate hypotension and hypoperfusion and, therefore, are contraindicated in circulatory shock. At therapeutic analgesic dosages, ambulatory patients are more likely to experience dizziness and hypotension than patients who are confined to bed. However, orthostatic hypotension may occur in supine patients upon rising. Therapy with opiate agonists should be administered cautiously and initiated at reduced dosages in patients with hypovolemia, or a predisposition to hypotension. When given by intramuscular or subcutaneous administration, clinicians should also be aware that impaired perfusion in these patients may prevent complete absorption of the drug. With repeated injections, an excessive amount may be absorbed suddenly if normal circulation is reestablished.
Major:
meloxicam
Meloxicam has a major potential interaction with Dehydration.
Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) has resulted in renal papillary necrosis and other renal injury. Renal toxicity has been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion; in such patients, NSAIDs may cause a dose-dependent reduction in prostaglandin synthesis and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk for this reaction include those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction; those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers; and older adult patients. Discontinuation of NSAID therapy generally leads to recovery to the pretreatment state. No information is available regarding NSAID use in patients with advanced renal disease; the renal effects of NSAIDs may hasten the progression of renal dysfunction in patients with preexisting renal disease. Volume status should be corrected in dehydrated or hypovolemic patients prior to initiating treatment. Renal function should be monitored in patients with renal or liver dysfunction, heart failure, dehydration, or hypovolemia during therapy. NSAIDs should be avoided in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function; if an NSAID is used in such patients, they should be monitored for signs of worsening renal function.
Dermatitis, Drug-Induced
Major:
meloxicam
Meloxicam has a major potential interaction with Dermatitis, Drug-Induced.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious skin adverse reactions (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis, and exfoliative dermatitis), which can be fatal. NSAIDs can also cause fixed drug eruption, and may present as generalized bullous fixed drug eruption, which can be life-threatening. These serious events may occur without warning. Patients should be advised to discontinue the NSAID and seek medical attention promptly at the first sign of skin rash or any other sign of hypersensitivity. NSAIDs are contraindicated in patients with previous serious skin reactions to these drugs.
Dermatitis Herpetiformis
Moderate:
Demi-Cof
The potassium iodide in Demi-Cof has a moderate potential interaction with Dermatitis Herpetiformis.
Potassium iodide should not be used in patients that have or have ever had dermatitis herpetiformis.
Diabetes Mellitus
Moderate:
Demi-Cof
The phenylephrine in Demi-Cof has a moderate potential interaction with Diabetes Mellitus.
Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.
Drug Dependence
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Drug Dependence.
Opiate agonists have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop after prolonged use. Abrupt cessation, reduction in dosage, or administration of an opiate antagonist such as naloxone may precipitate withdrawal symptoms. In patients who have developed tolerance to an opiate agonist, overdosage can still produce respiratory depression and death, and cross-tolerance usually will occur with other agents in the class. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with opiate agonists. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of opiate therapy should be undertaken gradually using a dosage-tapering schedule.
Fluid Retention
Major:
meloxicam
Meloxicam has a major potential interaction with Fluid Retention.
Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), including some topical formulations. NSAIDs (including topicals) can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events. NSAIDs should be used with caution in patients with preexisting fluid retention, hypertension, or history of heart failure. NSAIDs should be avoided in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure; if an NSAID is used in such patients, they should be monitored for signs of worsening heart failure. Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.
Gallbladder Disease
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Gallbladder Disease.
Opioid agonists may cause spasm of the sphincter of Oddi, which may increase biliary tract pressure. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions and transient elevations in serum amylase. Patients with biliary tract disease (including acute pancreatitis) should be regularly evaluated for worsening symptoms. Therapy with opioids should be administered cautiously in patients with biliary tract disease, gallbladder disease, or acute pancreatitis.
Gastritis/Duodenitis
Major:
meloxicam
Meloxicam has a major potential interaction with Gastritis/Duodenitis.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms. NSAIDs should be used with caution in patients with history of peptic ulcer disease and/or GI bleeding, as these patients had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Caution is also advised if NSAIDs are prescribed to patients with other factors that increase risk of GI bleeding, such as: prolonged NSAID therapy; concomitant use of oral corticosteroids, antiplatelet agents (e.g., aspirin), anticoagulants, selective serotonin reuptake inhibitors; alcohol use; smoking; history of gastrointestinal surgery or anastomosis, older age; poor general health status; and advanced liver disease and/or coagulopathy. Particular vigilance is necessary when treating older adult or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.

Gastrointestinal Obstruction
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Gastrointestinal Obstruction.
Opioid analgesics are contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus.
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Gastrointestinal Obstruction.
Narcotic (opioid) analgesic agents increase smooth muscle tone in the gastrointestinal tract and decrease peristalsis, which can lead to elevated intraluminal pressure, spasm, and constipation following prolonged use. In patients with severe or acute inflammatory bowel disease, the decrease in colonic motility may induce toxic megacolon. Therapy with opioids should be administered cautiously in patients with gastrointestinal obstruction, constipation, inflammatory bowel disease, or recent gastrointestinal tract surgery. Gastrointestinal effects appear to be the most pronounced with morphine.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Gastrointestinal Perforation
Major:
meloxicam
Meloxicam has a major potential interaction with Gastrointestinal Perforation.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms.

Glaucoma/Intraocular Hypertension
Moderate:
Demi-Cof
The phenylephrine in Demi-Cof has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors. In patients with anatomically narrow angles or narrow-angle glaucoma, pupillary dilation can provoke an acute attack. In patients with other forms of glaucoma, mydriasis may occasionally increase intraocular pressure. Therapy with sympathomimetic agents should be administered cautiously in patients with or predisposed to glaucoma, particularly narrow-angle glaucoma.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders.

Head Injury
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Head Injury.
The hypoventilation associated with administration of opiate agonists, particularly by the intravenous route, can induce cerebral hypoxia and vasodilatation with resultant increase in intracranial pressure. Opiate agonists should not be used in patients with suspected or known head injury or increased intracranial pressure. Also, clinicians treating such patients should be aware that opiate agonists may interfere with the evaluation of CNS function, especially with respect to consciousness levels, respiratory status, and pupillary changes.
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Head Injury.
Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration. Apnea may result from decreased respiratory drive as well as increased airway resistance, and rigidity of respiratory muscles may occur during rapid IV administration or when these agents are used in the induction of anesthesia. At therapeutic analgesic dosages, the respiratory effects are usually not clinically important except in patients with preexisting pulmonary impairment. Therapy with opiate agonists should be avoided or administered with extreme caution and initiated at reduced dosages in patients with severe CNS depression; sleep apnea; hypoxia, anoxia, or hypercapnia; upper airway obstruction; chronic pulmonary insufficiency; a limited ventilatory reserve; or other respiratory disorders. In the presence of excessive respiratory secretions, the use of opiate agonists may also be problematic because they decrease ciliary activity and reduce the cough reflex. Caution is also advised in patients who may be at increased risk for respiratory depression, such as comatose patients or those with head injury, intracranial lesions, or intracranial hypertension. Clinical monitoring of pulmonary function is recommended, and equipment for resuscitation should be immediately available if parenteral or neuraxial routes are used. Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Heart Disease
Moderate:
Demi-Cof
The potassium iodide in Demi-Cof has a moderate potential interaction with Heart Disease.
Potassium iodide should not be used in patients that have nodular thyroid disease and heart disease. Patients experiencing irregular heartbeats or chest pain should be instructed to stop treatment with potassium iodide.
Heart Failure
Major:
meloxicam
Meloxicam has a major potential interaction with Heart Failure.
Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) has resulted in renal papillary necrosis and other renal injury. Renal toxicity has been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion; in such patients, NSAIDs may cause a dose-dependent reduction in prostaglandin synthesis and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk for this reaction include those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction; those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers; and older adult patients. Discontinuation of NSAID therapy generally leads to recovery to the pretreatment state. No information is available regarding NSAID use in patients with advanced renal disease; the renal effects of NSAIDs may hasten the progression of renal dysfunction in patients with preexisting renal disease. Volume status should be corrected in dehydrated or hypovolemic patients prior to initiating treatment. Renal function should be monitored in patients with renal or liver dysfunction, heart failure, dehydration, or hypovolemia during therapy. NSAIDs should be avoided in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function; if an NSAID is used in such patients, they should be monitored for signs of worsening renal function.
Major:
meloxicam
Meloxicam has a major potential interaction with Heart Failure.
Fluid retention and edema have been reported in association with the use of nonsteroidal anti-inflammatory drugs (NSAIDs), including some topical formulations. NSAIDs (including topicals) can lead to new onset of hypertension or worsening of preexisting hypertension, either of which can contribute to the increased incidence of cardiovascular events. NSAIDs should be used with caution in patients with preexisting fluid retention, hypertension, or history of heart failure. NSAIDs should be avoided in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure; if an NSAID is used in such patients, they should be monitored for signs of worsening heart failure. Blood pressure and cardiovascular status should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.
High Blood Pressure

Particular vigilance is necessary when treating older adult or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.
History - Cerebrovascular Disease
Major:
meloxicam
Meloxicam has a major potential interaction with History - Cerebrovascular Disease.
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Clinical trials of several cyclooxygenase-2 (COX-2) selective and nonselective NSAIDs of up to 3 years duration have supported this increased risk. It is unclear from available data if the risk for cardiovascular thrombotic events is similar for all NSAIDs. Therapy with NSAIDs should be administered cautiously in patients with a history of cardiovascular or cerebrovascular disease. Patients should be treated with the lowest effective dosage for the shortest duration necessary. Appropriate antiplatelet therapy should be administered to patients requiring cardioprotection; however, there is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious cardiovascular thrombotic events associated with NSAID use, while the risk of serious gastrointestinal events is increased. Physicians and patients should remain alert for the development of adverse cardiovascular events throughout the entire duration of therapy, even without prior cardiovascular symptoms. Patients should be advised to promptly seek medical attention if they experience symptoms of cardiovascular thrombotic events (including chest pain, shortness of breath, weakness, or slurring of speech).
NSAIDs are contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Two large clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke.
The use of NSAIDs should be avoided in patients with a recent myocardial infarction unless the benefits are expected to outweigh the risk of recurrent cardiovascular thrombotic events. If an NSAID is used in patients with a recent myocardial infarction, they should be monitored for signs of cardiac ischemia.
History - Myocardial Infarction

If an NSAID is used in patients with a recent myocardial infarction, they should be monitored for signs of cardiac ischemia.
Hyperkalemia
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Hyperkalemia.
Increases in serum potassium concentration (including hyperkalemia) have been reported with use of nonsteroidal anti-inflammatory drugs (NSAIDs), even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state. Caution is advised in patients with hyperkalemia.
Hyperthyroidism
Major:
Demi-Cof
The phenylephrine in Demi-Cof has a major potential interaction with Hyperthyroidism.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Hyperthyroidism.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
Moderate:
Demi-Cof
The potassium iodide in Demi-Cof has a moderate potential interaction with Hyperthyroidism.
The use of iodide salts has been associated with the exacerbation or precipitation of hyperthyroidism in patients previously euthyroid. Induction of goiter has been reported in patients with hyperthyroidism. Iodide salts should be administered cautiously in patients with hyperthyroidism.
Hyponatremia

Hypotension
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Hypotension.
Opiate agonists can induce vasodilation and significant hypotension, particularly when given in high dosages and/or by rapid intravenous administration. Opiate analgesics cause vasodilatation that may exacerbate hypotension and hypoperfusion and, therefore, are contraindicated in circulatory shock. At therapeutic analgesic dosages, ambulatory patients are more likely to experience dizziness and hypotension than patients who are confined to bed. However, orthostatic hypotension may occur in supine patients upon rising. Therapy with opiate agonists should be administered cautiously and initiated at reduced dosages in patients with hypovolemia, or a predisposition to hypotension. When given by intramuscular or subcutaneous administration, clinicians should also be aware that impaired perfusion in these patients may prevent complete absorption of the drug. With repeated injections, an excessive amount may be absorbed suddenly if normal circulation is reestablished.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Hypotension.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
Infectious Gastroenteritis
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Infectious Gastroenteritis.
Narcotic (opioid) analgesic agents may prolong and/or worsen diarrhea associated with organisms that invade the intestinal mucosa, such as toxigenic Escherichia coli, Salmonella, Shigella, and pseudomembranous colitis due to broad-spectrum antibiotics. These agents decrease gastrointestinal motility, which may delay the excretion of infective gastroenteric organisms and/or their toxins. Other symptoms and complications such as fever, shedding of organisms, and extraintestinal illness may also be increased or prolonged. Therapy with opioids should be avoided or administered cautiously in patients with infectious diarrhea, particularly that due to pseudomembranous enterocolitis or enterotoxin-producing bacteria or if accompanied by high fever, pus, or blood in the stool.
Inflammatory Bowel Disease
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Inflammatory Bowel Disease.
Narcotic (opioid) analgesic agents increase smooth muscle tone in the gastrointestinal tract and decrease peristalsis, which can lead to elevated intraluminal pressure, spasm, and constipation following prolonged use. In patients with severe or acute inflammatory bowel disease, the decrease in colonic motility may induce toxic megacolon. Therapy with opioids should be administered cautiously in patients with gastrointestinal obstruction, constipation, inflammatory bowel disease, or recent gastrointestinal tract surgery. Gastrointestinal effects appear to be the most pronounced with morphine.
Intestinal Anastomoses
Major:

Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Liver Disease.
Limited pharmacokinetic data are available for the older, first-generation antihistamines. Many appear to be primarily metabolized by the liver, and both parent drugs and metabolites are excreted in the urine. Patients with renal and/or liver disease may be at greater risk for adverse effects from antihistamines due to drug and metabolite accumulation. Therapy with antihistamines should be administered cautiously in such patients. Lower initial dosages may be appropriate.
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Liver Disease.
Narcotic (opioid) analgesic agents are extensively metabolized by the liver, and several of them (e.g., codeine, hydrocodone, meperidine, methadone, morphine, propoxyphene) have active metabolites that are further converted to inactive substances. The serum concentrations of these agents and their metabolites may be increased and the half-lives prolonged in patients with impaired hepatic function. Therapy with opioids should be administered cautiously and initiated at reduced dosages in patients with liver disease. Subsequent doses should be titrated based on individual response rather than a fixed dosing schedule.
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Liver Disease.
Therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) should be administered cautiously in patients with preexisting liver disease. Periodic monitoring of liver function is recommended during prolonged therapy. NSAIDs are also highly protein-bound and some are extensively metabolized by the liver. Metabolic activity and/or plasma protein binding may be altered in patients with hepatic impairment. A dosage reduction may be required in some cases.

Pancreatitis
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Pancreatitis.
Opioid agonists may cause spasm of the sphincter of Oddi, which may increase biliary tract pressure. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions and transient elevations in serum amylase. Patients with biliary tract disease (including acute pancreatitis) should be regularly evaluated for worsening symptoms. Therapy with opioids should be administered cautiously in patients with biliary tract disease, gallbladder disease, or acute pancreatitis.

Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration. Apnea may result from decreased respiratory drive as well as increased airway resistance, and rigidity of respiratory muscles may occur during rapid IV administration or when these agents are used in the induction of anesthesia. At therapeutic analgesic dosages, the respiratory effects are usually not clinically important except in patients with preexisting pulmonary impairment. Therapy with opiate agonists should be avoided or administered with extreme caution and initiated at reduced dosages in patients with severe CNS depression; sleep apnea; hypoxia, anoxia, or hypercapnia; upper airway obstruction; chronic pulmonary insufficiency; a limited ventilatory reserve; or other respiratory disorders. In the presence of excessive respiratory secretions, the use of opiate agonists may also be problematic because they decrease ciliary activity and reduce the cough reflex. Caution is also advised in patients who may be at increased risk for respiratory depression, such as comatose patients or those with head injury, intracranial lesions, or intracranial hypertension. Clinical monitoring of pulmonary function is recommended, and equipment for resuscitation should be immediately available if parenteral or neuraxial routes are used. Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Renal Dysfunction
Major:
meloxicam
Meloxicam has a major potential interaction with Renal Dysfunction.
Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) has resulted in renal papillary necrosis and other renal injury. Renal toxicity has been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion; in such patients, NSAIDs may cause a dose-dependent reduction in prostaglandin synthesis and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk for this reaction include those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction; those taking diuretics, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers; and older adult patients. Discontinuation of NSAID therapy generally leads to recovery to the pretreatment state. No information is available regarding NSAID use in patients with advanced renal disease; the renal effects of NSAIDs may hasten the progression of renal dysfunction in patients with preexisting renal disease. Volume status should be corrected in dehydrated or hypovolemic patients prior to initiating treatment. Renal function should be monitored in patients with renal or liver dysfunction, heart failure, dehydration, or hypovolemia during therapy. NSAIDs should be avoided in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function; if an NSAID is used in such patients, they should be monitored for signs of worsening renal function.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Renal Dysfunction.
Limited pharmacokinetic data are available for the older, first-generation antihistamines. Many appear to be primarily metabolized by the liver, and both parent drugs and metabolites are excreted in the urine. Patients with renal and/or liver disease may be at greater risk for adverse effects from antihistamines due to drug and metabolite accumulation. Therapy with antihistamines should be administered cautiously in such patients. Lower initial dosages may be appropriate.
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Renal Dysfunction.
Although narcotic (opioid) analgesic agents are generally metabolized by the liver, renal impairment can alter the elimination of these agents and their metabolites (some of which are pharmacologically active), resulting in drug accumulation and increased risk of toxicity. Therapy with opioids should be administered cautiously and initiated at reduced dosages in patients with significantly impaired renal function. Subsequent doses should be titrated based on individual response rather than a fixed dosing schedule.
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Renal Dysfunction.
Increases in serum potassium concentration (including hyperkalemia) have been reported with use of nonsteroidal anti-inflammatory drugs (NSAIDs), even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state. Caution is advised in patients with hyperkalemia.
Respiratory Arrest
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Respiratory Arrest.
Opiate agonists may produce significant central nervous system and respiratory depression of varying duration, particularly when given in high dosages and/or by rapid intravenous administration. Apnea may result from decreased respiratory drive as well as increased airway resistance, and rigidity of respiratory muscles may occur during rapid IV administration or when these agents are used in the induction of anesthesia. At therapeutic analgesic dosages, the respiratory effects are usually not clinically important except in patients with preexisting pulmonary impairment. Therapy with opiate agonists should be avoided or administered with extreme caution and initiated at reduced dosages in patients with severe CNS depression; sleep apnea; hypoxia, anoxia, or hypercapnia; upper airway obstruction; chronic pulmonary insufficiency; a limited ventilatory reserve; or other respiratory disorders. In the presence of excessive respiratory secretions, the use of opiate agonists may also be problematic because they decrease ciliary activity and reduce the cough reflex. Caution is also advised in patients who may be at increased risk for respiratory depression, such as comatose patients or those with head injury, intracranial lesions, or intracranial hypertension. Clinical monitoring of pulmonary function is recommended, and equipment for resuscitation should be immediately available if parenteral or neuraxial routes are used. Naloxone may be administered to reverse clinically significant respiratory depression, which may be prolonged depending on the opioid agent, cumulative dose, and route of administration.
Seizures
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Seizures.
Narcotic (opioid) analgesic agents may increase the frequency of seizures in patients with seizure disorders, may increase the risk of seizures occurring in other clinical settings associated with seizures, and, at higher dosages, have been reported to induce seizures in patients without history of seizures. Patients with history of seizure disorders should be regularly evaluated for worsened seizure control during therapy. Prolonged meperidine use may increase the risk of toxicity (e.g., seizures) from the accumulation of the active metabolite (normeperidine).
Shock
Major:
Demi-Cof
The codeine in Demi-Cof has a major potential interaction with Shock.
Opiate agonists can induce vasodilation and significant hypotension, particularly when given in high dosages and/or by rapid intravenous administration. Opiate analgesics cause vasodilatation that may exacerbate hypotension and hypoperfusion and, therefore, are contraindicated in circulatory shock. At therapeutic analgesic dosages, ambulatory patients are more likely to experience dizziness and hypotension than patients who are confined to bed. However, orthostatic hypotension may occur in supine patients upon rising. Therapy with opiate agonists should be administered cautiously and initiated at reduced dosages in patients with hypovolemia, or a predisposition to hypotension. When given by intramuscular or subcutaneous administration, clinicians should also be aware that impaired perfusion in these patients may prevent complete absorption of the drug. With repeated injections, an excessive amount may be absorbed suddenly if normal circulation is reestablished.
Smoking
Major:
meloxicam
Meloxicam has a major potential interaction with Smoking.
Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can develop at any time, with or without warning symptoms. NSAIDs should be used with caution in patients with history of peptic ulcer disease and/or GI bleeding, as these patients had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Caution is also advised if NSAIDs are prescribed to patients with other factors that increase risk of GI bleeding, such as: prolonged NSAID therapy; concomitant use of oral corticosteroids, antiplatelet agents (e.g., aspirin), anticoagulants, selective serotonin reuptake inhibitors; alcohol use; smoking; history of gastrointestinal surgery or anastomosis, older age; poor general health status; and advanced liver disease and/or coagulopathy. Particular vigilance is necessary when treating older adult or debilitated patients since most postmarketing reports of fatal GI events occurred in these patients.
Thrombocytopathy
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Thrombocytopathy.
Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
Thrombocytopenia
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Thrombocytopenia.
Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
Urinary Retention
Moderate:
Demi-Cof
The codeine in Demi-Cof has a moderate potential interaction with Urinary Retention.
Narcotic (opioid) analgesic agents may inhibit the urinary voiding reflex and increase the tone of the vesical sphincter in the bladder. Acute urinary retention requiring catheterization may occur, particularly in patients with prostatic hypertrophy or urethral stricture and in older adult patients. These agents may also decrease urine production via direct effects on the kidney and central stimulation of the release of vasopressin. Therapy with opioids should be administered cautiously in patients with or predisposed to urinary retention and/or oliguria. The effects on smooth muscle tone appear to be the most pronounced with morphine.
Moderate:
Demi-Cof
The chlorpheniramine in Demi-Cof has a moderate potential interaction with Urinary Retention.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Vasculitis
Moderate:
Demi-Cof
The potassium iodide in Demi-Cof has a moderate potential interaction with Vasculitis.
People who are allergic to iodide or have hypocomplementemic vasculitis should not take potassium iodide.
Vitamin K Deficiency
Moderate:
meloxicam
Meloxicam has a moderate potential interaction with Vitamin K Deficiency.
Nonsteroidal anti-inflammatory drugs (NSAIDs) reversibly inhibit platelet adhesion and aggregation and may prolong bleeding time in some patients. With the exception of aspirin, the platelet effects seen with most NSAIDs at usual recommended dosages are generally slight and of relatively short duration but may be more pronounced in patients with underlying hemostatic abnormalities. Thrombocytopenia has also been reported rarely during NSAID use. Therapy with NSAIDs should be administered cautiously in patients with significant active bleeding or a hemorrhagic diathesis, including hemostatic and/or coagulation defects associated with hemophilia, vitamin K deficiency, hypoprothrombinemia, thrombocytopenia, thrombocytopathy, or severe hepatic impairment. NSAIDs that selectively inhibit cyclooxygenase-2 (i.e., COX-2 inhibitors) do not appear to affect platelet function or bleeding time at indicated dosages and may be preferable if risk of bleeding is a concern.
