FLUoxetine HYDROcodone
Applies to: Prozac (fluoxetine) and Lorcet 10 / 650 (acetaminophen / hydrocodone)
Monitor
Opioids may potentiate the effects of serotonergic agents and increase the risk of serotonin syndrome. The interaction has primarily been reported with the phenylpiperidine opioids (e.g., meperidine, fentanyl) and tramadol, which are known to possess some serotonergic activity, although a few cases have involved other opioids such as oxycodone, methadone, morphine, hydromorphone, codeine, and buprenorphine. Serotonin syndrome is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5-HT1A and 2A receptors. Symptoms of the serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea. Since many serotonergic agents can also cause central nervous system depression, concomitant use with opioids may result in increased sedation and impairment of judgment, thinking, and psychomotor skills.
Management
Caution is advised when opioids are used concomitantly with serotonergic agents such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), other antidepressants/psychotropic agents (e.g., amoxapine, buspirone, lithium, maprotiline, mirtazepine, nefazodone, trazodone, vilazodone), 5-HT1 receptor agonists (triptans), 5-HT3 receptor antagonists, cyclobenzaprine, dextromethorphan, 5-hydroxytryptophan, and St. John's wort. Patients should be monitored for symptoms of the serotonin syndrome during treatment. Particular caution is advised when increasing the dosages of these agents. If serotonin syndrome develops or is suspected during the course of therapy, all serotonergic agents should be discontinued immediately and supportive care rendered as necessary. Moderately ill patients may also benefit from the administration of a serotonin antagonist (e.g., cyproheptadine, chlorpromazine). Severe cases should be managed under consultation with a toxicologist and may require sedation, neuromuscular paralysis, intubation, and mechanical ventilation in addition to the other measures. Patients should also be advised of potentially additive central nervous system effects from these agents and to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them.

Minor drug interactions
Minor:
acetaminophen HYDROcodone
Applies to: Lorcet 10 / 650 (acetaminophen / hydrocodone) and Lorcet 10 / 650 (acetaminophen / hydrocodone)
Narcotic analgesics, anticholinergic agents, and/or agents with anticholinergic properties may delay and/or decrease the gastrointestinal absorption of acetaminophen (paracetamol) by reducing gastric motility and delaying gastric emptying. Available data suggest the clinical impact is minimal and generally does not necessitate dose adjustment.

Major:
acetaminophen Food/Lifestyle
Applies to: Lorcet 10 / 650 (acetaminophen / hydrocodone)
Generally avoid
Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.
Management
In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day.

Major:
HYDROcodone Food/Lifestyle
Applies to: Lorcet 10 / 650 (acetaminophen / hydrocodone)
Generally avoid
Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including hydrocodone. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.
Generally avoid
Consumption of alcohol while taking some sustained-release formulations of hydrocodone may cause rapid release of the drug, resulting in high systemic levels of hydrocodone that may be potentially lethal. Alcohol apparently can disrupt the release mechanism of some sustained-release formulations. In study subjects, the rate of absorption of hydrocodone from an extended-release formulation was found to be affected by coadministration with 40% alcohol in the fasted state, as demonstrated by an average 2.4-fold (up to 3.9-fold in one subject) increase in hydrocodone peak plasma concentration and a decrease in the time to peak concentration. Alcohol also increased the extent of absorption by an average of 1.2-fold (up to 1.7-fold in one subject).
Generally avoid
Grapefruit juice may increase the plasma concentrations of hydrocodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of hydrocodone by certain compounds present in grapefruit. Increased hydrocodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.
Management
Patients taking sustained-release formulations of hydrocodone should not consume alcohol or use medications that contain alcohol. In general, potent narcotics such as hydrocodone should not be combined with alcohol. Patients should also avoid consumption of grapefruit or grapefruit juice during treatment with hydrocodone.

Disease interactions
61 potential interactions Applies to: 47 conditions, including Depression, Bipolar Disorder, Constipation, Seizures, and Arrhythmia.
Acute Alcohol Intoxication
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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:
Lorcet 10/650
The acetaminophen in Lorcet 10/650 has a major potential interaction with Alcoholism.
Chronic alcohol abusers may be at increased risk of hepatotoxicity during treatment with acetaminophen (APAP). Severe liver injury, including cases of acute liver failure resulting in liver transplant and death, has been reported in patients using acetaminophen. Therapy with acetaminophen should be administered cautiously, if at all, in patients who consume three or more alcoholic drinks a day. In general, patients should avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure. They should also be advised to seek medical attention if they experience signs and symptoms of liver injury such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice.
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Altered Consciousness
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Anorexia/Feeding Problems
Minor:
Prozac
The FLUoxetine in Prozac has a minor potential interaction with Anorexia/Feeding Problems.
The use of selective serotonin reuptake inhibitors (SSRIs) may occasionally cause significant weight loss, which may be undesirable in patients suffering from anorexia, malnutrition or excessive weight loss. Anorexia may occur in approximately 5% to 10% of patients. Weight change should be monitored during therapy if an SSRI is used in these patients.
Arrhythmia
Moderate:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Biliary Obstruction
Moderate:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Bipolar Disorder
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Bipolar Disorder.
Selective serotonin reuptake inhibitors (SSRIs), like other antidepressants, may occasionally cause or activate mania or hypomania. The reported incidence ranged from 0.1% to 2% in premarketing testing of several SSRIs. Patients with bipolar disorder are generally more likely to experience mania from antidepressants. Therapy with SSRIs should be administered cautiously in patients with a history of mania or bipolar disorder. Prior to initiating treatment, it is recommended to adequately screen patients for bipolar disorder, including a family history of suicide, bipolar disorder, and depression.
Bleeding Disorder
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Bleeding Disorder.
The use of selective serotonin reuptake inhibitors (SSRIs) has been associated with altered platelet function. Petechiae, purpura, ecchymosis, increased bleeding times, epistaxis and gastrointestinal hemorrhage have been reported. Therapy with SSRIs should be administered cautiously in patients with severe active bleeding or a hemorrhagic diathesis.
Brain Tumor
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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. 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.
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Cerebral Vascular Disorder
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.

Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 has a major potential interaction with Cerebral Vascular Disorder.
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.

Coagulation Defects and Disorders
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Coagulation Defects and Disorders.
The use of selective serotonin reuptake inhibitors (SSRIs) has been associated with altered platelet function. Petechiae, purpura, ecchymosis, increased bleeding times, epistaxis and gastrointestinal hemorrhage have been reported. Therapy with SSRIs should be administered cautiously in patients with severe active bleeding or a hemorrhagic diathesis.
Constipation
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Dehydration
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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:
Lorcet 10/650
The acetaminophen in Lorcet 10/650 has a major potential interaction with Dehydration.
Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Dehydration.
The use of selective serotonin reuptake inhibitors (SSRIs) has rarely been associated with hyponatremia, sometimes secondary to development of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). These events have generally been reversible following discontinuation of SSRI therapy and/or medical intervention. SSRI-related hyponatremia may be more common in elderly female patients and those who are volume-depleted or receiving concomitant diuretic therapy. Caution may be warranted when SSRI therapy is administered in these patients and patients with preexisting hyponatremia or SIADH. Serum electrolytes, especially sodium as well as BUN and plasma creatinine, should be monitored regularly.
Depression
Major:
Prozac
The FLUoxetine in Prozac has a major potential interaction with Depression.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Families and caregivers should be advised of the need for close observation and communication with the treating physician. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Depression.
Selective serotonin reuptake inhibitors (SSRIs), like other antidepressants, may occasionally cause or activate mania or hypomania. The reported incidence ranged from 0.1% to 2% in premarketing testing of several SSRIs. Patients with bipolar disorder are generally more likely to experience mania from antidepressants. Therapy with SSRIs should be administered cautiously in patients with a history of mania or bipolar disorder. Prior to initiating treatment, it is recommended to adequately screen patients for bipolar disorder, including a family history of suicide, bipolar disorder, and depression.
Diabetes Mellitus
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Diabetes Mellitus.
Fluoxetine may alter blood glucose control in patients with diabetes. Hypoglycemia may occur during therapy with fluoxetine, and hyperglycemia may occur following discontinuation of the drug. Dosage adjustments in insulin and/or oral hypoglycemic medications may be necessary in patients with diabetes whenever fluoxetine therapy is initiated or discontinued.
Drug Dependence
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Failure to Thrive
Minor:
Prozac
The FLUoxetine in Prozac has a minor potential interaction with Failure to Thrive.
The use of selective serotonin reuptake inhibitors (SSRIs) may occasionally cause significant weight loss, which may be undesirable in patients suffering from anorexia, malnutrition or excessive weight loss.

Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.
Moderate:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Liver Disease.
Selective serotonin reuptake inhibitors (SSRIs) are primarily metabolized by the liver. The plasma concentrations of SSRIs and their metabolites may be increased and the half-lives prolonged in patients with impaired hepatic function.

Families and caregivers should be advised of the need for close observation and communication with the treating physician. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Pulmonary Impairment
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 has a major potential interaction with Pulmonary Impairment.
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.

Renal Dysfunction
Moderate:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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.
Minor:
Prozac
The FLUoxetine in Prozac has a minor potential interaction with Renal Dysfunction.
Fluoxetine is primarily metabolized by the liver. All but one metabolites are inactive, and they are excreted by the kidney. The clearance of norfluoxetine, the active metabolite, is not dependent on renal function. Dosage adjustments are generally not deemed necessary in patients with impaired renal function, although the clinical significance of possible metabolite accumulation is unknown. Caution may be warranted when fluoxetine therapy is administered in patients with severe renal dysfunction.
Respiratory Arrest
Major:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 has a major potential interaction with Respiratory Arrest.

Seizures
Moderate:
Lorcet 10/650
The HYDROcodone in Lorcet 10/650 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).
Moderate:
Prozac
The FLUoxetine in Prozac has a moderate potential interaction with Seizures.
Selective serotonin reuptake inhibitors (SSRIs) may trigger seizures in approximately 0.2% of patients, and some of them are not recommended in patients with unstable epilepsy. Therapy with SSRIs should be administered cautiously in patients with seizure disorders.
