Major:

pimozide Food/Lifestyle

Applies to: pimozide

You should avoid the consumption of large amounts of grapefruits and grapefruit juice while taking pimozide. Grapefruit can raise the levels of pimozide in your body. This can affect the rhythm of your heart and cause other side effects. Call your doctor if you have symptoms of blurred vision or nausea. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or fast or pounding heartbeats during treatment with pimozide. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor. You should avoid or limit the use of alcohol while being treated with pimozide. Alcohol can increase the nervous system side effects of pimozide such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. Talk to your doctor or pharmacist if you have any questions or concerns.

Moderate food/lifestyle interactions

Moderate:

aspirin Alcohol (Ethanol)

Applies to: CVS Extra Strength Headache Relief (acetaminophen / aspirin / caffeine)

Ask your doctor before using aspirin together with ethanol (alcohol). Do not drink alcohol while taking aspirin. Alcohol can increase your risk of stomach bleeding caused by aspirin. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Abnormal Electrocardiogram

Major:

pimozide

Pimozide has a major potential interaction with Abnormal Electrocardiogram.

The use of pimozide is contraindicated in patients with congenital or acquired QT interval prolongation syndromes or a history of cardiac arrhythmias. Pimozide can prolong the QT interval of the electrocardiogram. The risk of torsade de pointes is progressively increased as the degree of prolongation becomes greater. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of pimozide on the QT interval and should be corrected prior to institution of pimozide therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with pimozide. Because sudden deaths have been reported in patients using pimozide, and electrocardiogram should be performed before starting treatment and periodically thereafter, especially during periods of dose adjustment.

Acute Alcohol Intoxication

Major:

pimozide

Pimozide has a major potential interaction with Acute Alcohol Intoxication.

The use of most miscellaneous antipsychotics is contraindicated in patients with severe central nervous system depression or comatose states from any cause (e.g., lesion, disease, drug or alcohol induced).

Alcoholism

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Alcoholism.

Salicylates, particularly aspirin, can cause dose-related gastrointestinal bleeding and mucosal damage, which may occur independently of each other. Occult, often asymptomatic GI blood loss is quite common with usual dosages of aspirin and stems from the drug's local effect on the GI mucosa. During chronic therapy, this type of bleeding may occasionally produce iron deficiency anemia. In contrast, major upper GI bleeding rarely occurs except in patients with active peptic ulcers or recent GI bleeding. However, these patients generally do not experience greater occult blood loss than healthy patients following small doses of aspirin. Mucosal damage associated with the use of salicylates may lead to development of peptic ulcers with or without bleeding, reactivation of latent ulcers, and ulcer perforation. Therapy with salicylates and related agents such as salicylamide should be considered and administered cautiously in patients with a history of GI disease or alcoholism, particularly if they are elderly and/or debilitated, since such patients may be more susceptible to the GI toxicity of these drugs and seem to tolerate ulceration and bleeding less well than other individuals. Extreme caution and thorough assessment of risks and benefits are warranted in patients with active or recent GI bleeding or lesions. Whenever possible, especially if prolonged use is anticipated, treatment with non-ulcerogenic agents should be attempted first. If salicylates are used, close monitoring for toxicity is recommended. Some adverse GI effects may be minimized by administration with high dosages of antacids, use of enteric-coated or extended-release formulations, and/or concurrent use of a histamine H2-receptor antagonist or a cytoprotective agent such as misoprostol. Patients with active peptic ulceration or GI bleeding treated with salicylates should generally be administered a concomitant anti-ulcer regimen.

Major:

CVS Extra Strength Headache Relief

The acetaminophen in CVS Extra Strength Headache Relief 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:

pimozide

Pimozide has a major potential interaction with Alcoholism.

The use of neuroleptic agents is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of neuroleptic agents may be additive with those of alcohol. Severe respiratory depression and respiratory arrest may occur. Therapy with neuroleptic agents should be administered cautiously in patients who might be prone to acute alcohol intake.

Major:

pimozide

Pimozide has a major potential interaction with Alcoholism.

Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Alcoholism.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Altered Consciousness

Major:

pimozide

Pimozide has a major potential interaction with Altered Consciousness.

The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.

Major:

pimozide

Pimozide has a major potential interaction with Altered Consciousness.

The use of most miscellaneous antipsychotics is contraindicated in patients with severe central nervous system depression or comatose states from any cause (e.g., lesion, disease, drug or alcohol induced).

Anemia

Moderate:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a moderate potential interaction with Anemia.

Occult, often asymptomatic GI blood loss occurs quite frequently with the use of normal dosages of aspirin and stems from the drug's local effect on the GI mucosa. During chronic therapy, this type of bleeding may occasionally produce iron deficiency anemia. Other salicylates reportedly cause little or no GI blood loss at usual dosages, but may do so at high dosages. Prolonged therapy with salicylates, particularly aspirin, should be administered cautiously in patients with or predisposed to anemia. Periodic monitoring of hematocrit is recommended. The same precautions should also be observed with the use of related agents such as salicylamide because of their structural and pharmacological similarities to salicylate.

Angina

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Angina.

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

Arrhythmia

Major:

pimozide

Pimozide has a major potential interaction with Arrhythmia.

The use of pimozide is contraindicated in patients with congenital or acquired QT interval prolongation syndromes or a history of cardiac arrhythmias. Pimozide can prolong the QT interval of the electrocardiogram. The risk of torsade de pointes is progressively increased as the degree of prolongation becomes greater. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of pimozide on the QT interval and should be corrected prior to institution of pimozide therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with pimozide. Because sudden deaths have been reported in patients using pimozide, and electrocardiogram should be performed before starting treatment and periodically thereafter, especially during periods of dose adjustment.

Asthma

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief 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.

Bleeding Disorder

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Bleeding Disorder.

The use of aspirin is contraindicated in patients with significant active bleeding or hemorrhagic disorders such as hemophilia, von Willebrand's disease, or telangiectasia. Aspirin interferes with coagulation by irreversibly inhibiting platelet aggregation and prolonging bleeding time. The non-aceylated salicylates (i.e. salicylate salts such as sodium or magnesium salicylate) do not demonstrate these effects and may be appropriate substitutions in these patients. However, all salicylates can interfere with the action of vitamin K and induce a dose-dependent alteration in hepatic synthesis of coagulation factors VII, IX and X. At usual recommended dosages, a slight increase in prothrombin time (PT) may occur. Therapy with salicylates, especially aspirin, should be administered with extreme caution in patients with hypoprothrombinemia, vitamin K deficiency, thrombocytopenia, thrombotic thrombocytopenic purpura, severe hepatic impairment, or anticoagulant use.

Breast Cancer

Moderate:

pimozide

Pimozide has a moderate potential interaction with Breast Cancer.

The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Breast Cancer.

Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.

Central Nervous System Disorders

Major:

pimozide

Pimozide has a major potential interaction with Central Nervous System Disorders.

Antipsychotics can lower the seizure threshold and trigger seizures in a dose-dependent manner. Seizures have been reported in patients receiving antipsychotic therapy and may occur in epileptic patients even with maintenance of routine anticonvulsant treatment. Therapy with antipsychotics should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. High dosages should be avoided if possible.

Coagulation Defects and Disorders

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Coagulation Defects and Disorders.

The use of aspirin is contraindicated in patients with significant active bleeding or hemorrhagic disorders such as hemophilia, von Willebrand's disease, or telangiectasia. Aspirin interferes with coagulation by irreversibly inhibiting platelet aggregation and prolonging bleeding time. The non-aceylated salicylates (i.e. salicylate salts such as sodium or magnesium salicylate) do not demonstrate these effects and may be appropriate substitutions in these patients. However, all salicylates can interfere with the action of vitamin K and induce a dose-dependent alteration in hepatic synthesis of coagulation factors VII, IX and X. At usual recommended dosages, a slight increase in prothrombin time (PT) may occur. Therapy with salicylates, especially aspirin, should be administered with extreme caution in patients with hypoprothrombinemia, vitamin K deficiency, thrombocytopenia, thrombotic thrombocytopenic purpura, severe hepatic impairment, or anticoagulant use.

Colonic Ulceration

Patients with active peptic ulceration or GI bleeding treated with salicylates should generally be administered a concomitant anti-ulcer regimen.

Dehydration

Major:

CVS Extra Strength Headache Relief

The acetaminophen in CVS Extra Strength Headache Relief 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.

Dementia

Major:

pimozide

Pimozide has a major potential interaction with Dementia.

Antipsychotic drugs are not approved for the treatment of patients with dementia-related psychosis. Older patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death; although the causes were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. A causal relationship with antipsychotic use has not been established. In controlled trials in older patients with dementia-related psychosis, patients randomized to risperidone, aripiprazole, and olanzapine had higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, compared to patients treated with placebo.

Depression

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Depression.

The use of CNS stimulants can cause psychotic symptoms, suicidal ideation, and aggression, and can exacerbate symptoms of behavior disturbance and thought disorder; CNS stimulants may induce a manic or mixed episode in patients with bipolar disorder. Psychiatric symptoms have been reported in patients with and without history of psychiatric disorders. All patients (particularly those with psychotic or bipolar disorders) should be monitored closely, especially during treatment initiation and at times of dose changes. Extreme caution should be exercised when CNS stimulants are given to patients with a history of psychosis, depression, mania, or bipolar disorder. Prior to initiating therapy, all patients should be screened for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or family history of suicide, bipolar disease, or depression). If any psychiatric symptoms emerge or are exacerbated, treatment suspension should be considered. Some CNS stimulants are contraindicated in patients with marked agitation or anxiety.

Diarrhea

Major:

pimozide

Pimozide has a major potential interaction with Diarrhea.

The use of pimozide is contraindicated in patients with congenital or acquired QT interval prolongation syndromes or a history of cardiac arrhythmias. Pimozide can prolong the QT interval of the electrocardiogram. The risk of torsade de pointes is progressively increased as the degree of prolongation becomes greater. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of pimozide on the QT interval and should be corrected prior to institution of pimozide therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with pimozide. Because sudden deaths have been reported in patients using pimozide, and electrocardiogram should be performed before starting treatment and periodically thereafter, especially during periods of dose adjustment.

G-6-PD Deficiency

Moderate:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a moderate potential interaction with G-6-PD Deficiency.

Salicylates, particularly aspirin, may cause or aggravate hemolysis in patients with pyruvate kinase or glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. However, this effect has not been clearly established. Until more data are available, therapy with salicylates should be administered cautiously in patients with G-6-PD deficiency. The same precaution should also be observed with the use of related agents such as salicylamide because of their structural and pharmacological similarities to salicylate.

Gastritis/Duodenitis

Major:

Gastrointestinal Obstruction

Moderate:

pimozide

Pimozide has a moderate potential interaction with Gastrointestinal Obstruction.

Most neuroleptic agents have anticholinergic activity, to which elderly patients are particularly sensitive. Clozapine and low- potency agents such as chlorpromazine and thioridazine tend to exhibit the greatest degree of anticholinergic effects in the class, while haloperidol as well as the newer, atypical agents like quetiapine, risperidone and ziprasidone have generally been associated with very low frequencies of anticholinergic adverse effects. Therapy with neuroleptic agents should be administered cautiously 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.

Gastrointestinal Perforation

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Gastrointestinal Perforation.

Salicylates, particularly aspirin, can cause dose-related gastrointestinal bleeding and mucosal damage, which may occur independently of each other. Occult, often asymptomatic GI blood loss is quite common with usual dosages of aspirin and stems from the drug's local effect on the GI mucosa. During chronic therapy, this type of bleeding may occasionally produce iron deficiency anemia.

GERD

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with GERD.

Methylxanthines increase gastric acidity and may also relax lower esophageal sphincter, which can lead to gastric reflux into the esophagus. Therapy with products containing methylxanthines should be administered cautiously in patients with significant gastroesophageal reflux.

Glaucoma/Intraocular Hypertension

Moderate:

pimozide

Pimozide has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Most neuroleptic agents have anticholinergic activity, to which elderly patients are particularly sensitive. Clozapine and low- potency agents such as chlorpromazine and thioridazine tend to exhibit the greatest degree of anticholinergic effects in the class, while haloperidol as well as the newer, atypical agents like quetiapine, risperidone and ziprasidone have generally been associated with very low frequencies of anticholinergic adverse effects.

Head Injury

Moderate:

pimozide

Pimozide has a moderate potential interaction with Head Injury.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Heart Attack

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Heart Attack.

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

Heart Disease

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Heart Disease.

Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias, and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam, and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Hemodialysis

Moderate:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a moderate potential interaction with Hemodialysis.

Salicylate and its metabolites are readily removed by hemodialysis and, to a lesser extent, by peritoneal dialysis. Doses should either be scheduled for administration after dialysis or supplemental doses be given after dialysis.

High Blood Pressure

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with High Blood Pressure.

CNS stimulants increase blood pressure and heart rate; the use of some agents may be contraindicated in patients with severe/uncontrolled hypertension. Caution should be used when administering to patients with preexisting high blood pressure (even mild hypertension) and other cardiovascular conditions. All patients under treatment should be regularly monitored for potential tachycardia and hypertension.

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with High Blood Pressure.

Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias, and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam, and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with High Blood Pressure.

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

History, Peptic Ulcer

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with History, Peptic Ulcer.

Salicylates, particularly aspirin, can cause dose-related gastrointestinal bleeding and mucosal damage, which may occur independently of each other. Occult, often asymptomatic GI blood loss is quite common with usual dosages of aspirin and stems from the drug's local effect on the GI mucosa. During chronic therapy, this type of bleeding may occasionally produce iron deficiency anemia. In contrast, major upper GI bleeding rarely occurs except in patients with active peptic ulcers or recent GI bleeding. However, these patients generally do not experience greater occult blood loss than healthy patients following small doses of aspirin. Mucosal damage associated with the use of salicylates may lead to development of peptic ulcers with or without bleeding, reactivation of latent ulcers, and ulcer perforation. Therapy with salicylates and related agents such as salicylamide should be considered and administered cautiously in patients with a history of GI disease or alcoholism, particularly if they are elderly and/or debilitated, since such patients may be more susceptible to the GI toxicity of these drugs and seem to tolerate ulceration and bleeding less well than other individuals. Extreme caution and thorough assessment of risks and benefits are warranted in patients with active or recent GI bleeding or lesions. Whenever possible, especially if prolonged use is anticipated, treatment with non-ulcerogenic agents should be attempted first. If salicylates are used, close monitoring for toxicity is recommended. Some adverse GI effects may be minimized by administration with high dosages of antacids, use of enteric-coated or extended-release formulations, and/or concurrent use of a histamine H2-receptor antagonist or a cytoprotective agent such as misoprostol. Patients with active peptic ulceration or GI bleeding treated with salicylates should generally be administered a concomitant anti-ulcer regimen.

Hyperprolactinemia

Moderate:

pimozide

Pimozide has a moderate potential interaction with Hyperprolactinemia.

The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Hyperprolactinemia.

Antipsychotic drugs can elevate serum prolactin concentrations, and this elevation persists during chronic administration. This should be considered if therapy will be prescribed in patients with previously detected breast cancer as one-third of human breast cancers are prolactin-dependent in vitro. Associated disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported. Appropriate laboratory testing and follow-up is advised.

Hyperthyroidism

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Hyperthyroidism.

Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias, and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam, and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

Hypokalemia

Major:

pimozide

Pimozide has a major potential interaction with Hypokalemia.

The use of pimozide is contraindicated in patients with congenital or acquired QT interval prolongation syndromes or a history of cardiac arrhythmias. Pimozide can prolong the QT interval of the electrocardiogram. The risk of torsade de pointes is progressively increased as the degree of prolongation becomes greater. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of pimozide on the QT interval and should be corrected prior to institution of pimozide therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with pimozide. Because sudden deaths have been reported in patients using pimozide, and electrocardiogram should be performed before starting treatment and periodically thereafter, especially during periods of dose adjustment.

Influenza

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Influenza.

The use of salicylates, primarily aspirin, in children with varicella infections or influenza-like illnesses has been associated with an increased risk of Reye's syndrome. Although a causal relationship has not been established, the majority of evidence to date seems to support the association. Most authorities, including the American Academy of Pediatrics Committee on Infectious Diseases, recommend avoiding the use of salicylates in children and teenagers with known or suspected varicella or influenza and during presumed outbreaks of influenza. If antipyretic or analgesic therapy is indicated under these circumstances, acetaminophen may be an appropriate alternative. The same precautions should also be observed with related agents such as salicylamide or diflunisal because of their structural and pharmacological similarities to salicylate.

Liver Disease

Major:

CVS Extra Strength Headache Relief

The acetaminophen in CVS Extra Strength Headache Relief has a major potential interaction with Liver Disease.

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:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a moderate potential interaction with Liver Disease.

The use of salicylates has occasionally been associated with acute, reversible hepatotoxicity, primarily manifested as elevations of serum transaminases, alkaline phosphatase and/or, rarely, bilirubin. Hepatic injury consistent with chronic active hepatitis has also been reported in a few patients, which resulted rarely in encephalopathy or death. Salicylate-induced hepatotoxicity appears to be dependent on serum salicylate concentration (> 25 mg/dL) and has occurred most frequently in patients with juvenile arthritis, active systemic lupus erythematosus, rheumatic fever, or preexisting hepatic impairment. Therapy with salicylates, particularly when given in high dosages, should be administered cautiously in these patients, and periodic monitoring of liver function is recommended. The same precautions should also be observed with the use of related agents such as salicylamide because of their structural and pharmacological similarities to salicylate. A dosage reduction may be necessary if liver function abnormalities develop and serum salicylate concentration exceeds 25 mg/dL, although serum transaminase elevations may sometimes be transient and return to pretreatment values despite continued therapy without dosage adjustment.

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Liver Disease.

In general, CNS stimulants are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with CNS stimulants should be administered cautiously in patients with moderate to severe liver disease, and the dosage should be adjusted accordingly in certain agents. Additionally, postmarketing reports have shown that atomoxetine can cause severe liver injury; laboratory testing should be done at the first sign/symptom of liver dysfunction (jaundice, dark urine, upper quadrant tenderness) and treatment should be discontinued in patients with evidence of liver injury.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Liver Disease.

Pimozide is extensively metabolized by the liver, and both parent drug and metabolites are eliminated by the kidney. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects due to drug and metabolite accumulation. Therapy with pimozide should be administered cautiously in such patients.

Magnesium Imbalance

Major:

pimozide

Pimozide has a major potential interaction with Magnesium Imbalance.

The use of pimozide is contraindicated in patients with congenital or acquired QT interval prolongation syndromes or a history of cardiac arrhythmias. Pimozide can prolong the QT interval of the electrocardiogram. The risk of torsade de pointes is progressively increased as the degree of prolongation becomes greater. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of pimozide on the QT interval and should be corrected prior to institution of pimozide therapy.

The acetaminophen in CVS Extra Strength Headache Relief has a major potential interaction with Malnourishment.

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.

Neuroleptic Malignant Syndrome

Major:

pimozide

Pimozide has a major potential interaction with Neuroleptic Malignant Syndrome.

Neuroleptic Malignant Syndrome (NMS), a potentially fatal symptom complex, has been reported in association with the use of antipsychotic drugs. The diagnostic evaluation is complicated and the management requires immediate discontinuation of the antipsychotic therapy and intensive symptomatic treatment and medical monitoring. If a patient that has recovered from NMS requires antipsychotic drug treatment again, the reintroduction of therapy should be carefully considered as NMS recurrences have been reported.

Major:

pimozide

Pimozide has a major potential interaction with Neuroleptic Malignant Syndrome.

The central dopaminergic blocking effects of neuroleptic agents may precipitate or aggravate a potentially fatal symptom complex known as neuroleptic malignant syndrome (NMS). NMS is observed most frequently when high-potency agents like haloperidol are administered intramuscularly, but may occur with any neuroleptic agent given for any length of time. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria, and acute renal failure. Neuroleptic agents should not be given to patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of neuroleptic agents should be carefully considered, since NMS may recur.

Neutropenia

Moderate:

pimozide

Pimozide has a moderate potential interaction with Neutropenia.

The use of antipsychotics has been associated with events of leukopenia, neutropenia and agranulocytosis. Possible risk factors include preexisting low white blood cell count, and history of drug induced leukopenia/neutropenia. Patients with these risk factors should have complete blood count monitored frequently during the first few months of therapy. Patients should also be monitored for any signs or symptoms of infection. Treatment should be discontinued in any patient who develops a sore throat, fever, stomatitis, or other signs of infection along with a low WBC count or severe neutropenia (ANC < 1000/mm3).

Noninfectious Colitis

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Noninfectious Colitis.

Salicylates, particularly aspirin, can cause dose-related gastrointestinal bleeding and mucosal damage, which may occur independently of each other. Occult, often asymptomatic GI blood loss is quite common with usual dosages of aspirin and stems from the drug's local effect on the GI mucosa. During chronic therapy, this type of bleeding may occasionally produce iron deficiency anemia. In contrast, major upper GI bleeding rarely occurs except in patients with active peptic ulcers or recent GI bleeding. However, these patients generally do not experience greater occult blood loss than healthy patients following small doses of aspirin. Mucosal damage associated with the use of salicylates may lead to development of peptic ulcers with or without bleeding, reactivation of latent ulcers, and ulcer perforation. Therapy with salicylates and related agents such as salicylamide should be considered and administered cautiously in patients with a history of GI disease or alcoholism, particularly if they are elderly and/or debilitated, since such patients may be more susceptible to the GI toxicity of these drugs and seem to tolerate ulceration and bleeding less well than other individuals. Extreme caution and thorough assessment of risks and benefits are warranted in patients with active or recent GI bleeding or lesions. Whenever possible, especially if prolonged use is anticipated, treatment with non-ulcerogenic agents should be attempted first. If salicylates are used, close monitoring for toxicity is recommended. Some adverse GI effects may be minimized by administration with high dosages of antacids, use of enteric-coated or extended-release formulations, and/or concurrent use of a histamine H2-receptor antagonist or a cytoprotective agent such as misoprostol. Patients with active peptic ulceration or GI bleeding treated with salicylates should generally be administered a concomitant anti-ulcer regimen.

Parkinsonism

Moderate:

pimozide

Pimozide has a moderate potential interaction with Parkinsonism.

The use of neuroleptic agents is associated with pseudo-parkinsonian symptoms such as akinesia, bradykinesia, tremors, pill-rolling motion, cogwheel rigidity, and postural abnormalities including stooped posture and shuffling gait. The onset is usually 1 to 2 weeks following initiation of therapy or an increase in dosage. Older neuroleptic agents such as haloperidol are more likely to induce these effects, and their use may be contraindicated in patients with Parkinson's disease or parkinsonian symptoms.

Peptic Ulcer

Major:

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Peptic Ulcer.

Methylxanthines are known to stimulate peptic acid secretion. Therapy with products containing methylxanthines should be administered with extreme caution in patients with active peptic ulcer disease. Some manufacturers consider their use to be contraindicated under such circumstance.

Peripheral Arterial Disease

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Peripheral Arterial Disease.

Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. Additionally, stroke, myocardial infarction, chest pain, syncope, arrhythmias, and other symptoms have been reported in adults under treatment. A careful assessment of the cardiovascular status should be done in patients being considered for treatment. This includes family history, physical exam, and further cardiac evaluation (EKG and echocardiogram). Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Phenylketonuria

Moderate:

CVS Extra Strength Headache Relief

The acetaminophen in CVS Extra Strength Headache Relief has a moderate potential interaction with Phenylketonuria.

Several oral acetaminophen and acetaminophen-combination products, particularly flavored chewable tablets, contain the artificial sweetener, aspartame (NutraSweet). Aspartame is converted to phenylalanine in the gastrointestinal tract following ingestion. Chewable and effervescent formulations of acetaminophen products may also contain phenylalanine. The aspartame/phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).

Pheochromocytoma

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Pheochromocytoma.

Many CNS stimulants are contraindicated in patients with significant cardiovascular impairment such as uncompensated heart failure, severe coronary disease, severe hypertension (including that associated with hyperthyroidism or pheochromocytoma), cardiac structural abnormalities, serious arrhythmias, etc. Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who are treated with CNS stimulants at the recommended dosages for attention deficit hyperactivity disorder; use of these agents should be avoided in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease.

Patients who develop symptoms should have a detailed cardiac evaluation and if needed, treatment should be suspended.

Pituitary Tumor

Major:

pimozide

Pimozide has a major potential interaction with Pituitary Tumor.

Pimozide may have a tumorigenic potential and has been shown to cause a dose-related increase in pituitary tumors in mice. When treated for up to 18 months, pituitary gland changes that occurred were characterized as hyperplasia at doses approximating the human dose and adenoma at doses about 15 times the maximum recommended human dose on a mg/kg basis. The full significance of this finding is unknown but should be considered when prescribing pimozide, particularly in patients with preexisting pituitary tumors.

Post MI Syndrome

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Post MI Syndrome.

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

Psychosis

Major:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a major potential interaction with Psychosis.

The use of CNS stimulants can cause psychotic symptoms, suicidal ideation, and aggression, and can exacerbate symptoms of behavior disturbance and thought disorder; CNS stimulants may induce a manic or mixed episode in patients with bipolar disorder. Psychiatric symptoms have been reported in patients with and without history of psychiatric disorders. All patients (particularly those with psychotic or bipolar disorders) should be monitored closely, especially during treatment initiation and at times of dose changes. Extreme caution should be exercised when CNS stimulants are given to patients with a history of psychosis, depression, mania, or bipolar disorder. Prior to initiating therapy, all patients should be screened for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or family history of suicide, bipolar disease, or depression). If any psychiatric symptoms emerge or are exacerbated, treatment suspension should be considered. Some CNS stimulants are contraindicated in patients with marked agitation or anxiety.

Renal Dysfunction

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Renal Dysfunction.

Salicylate and its metabolites are eliminated almost entirely by the kidney. Therapy with salicylate drugs should be administered cautiously in patients with renal impairment, especially if it is severe. Reduced dosages may be necessary to avoid drug accumulation. Clinical monitoring of renal function is recommended during prolonged therapy, since the use of salicylate drugs has rarely been associated with renal toxicities, including elevations in serum creatinine, renal papillary necrosis, and acute tubular necrosis with renal failure. Most of the data have been derived from experience with aspirin but may apply to other salicylates as well. In patients with impaired renal function, aspirin has caused reversible and sometimes marked decreases in renal blood flow and glomerular filtration rate. Adverse renal effects have usually reversed rapidly following withdrawal of aspirin therapy.

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Renal Dysfunction.

Overall CNS stimulants should be administered with caution in patients with significantly impaired renal function as the reduction in the rate of elimination may alter the therapeutic response. The dosage should be adjusted accordingly in certain agents.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Renal Dysfunction.

Pimozide is extensively metabolized by the liver, and both parent drug and metabolites are eliminated by the kidney. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects due to drug and metabolite accumulation. Therapy with pimozide should be administered cautiously in such patients.

Respiratory Arrest

Major:

pimozide

Pimozide has a major potential interaction with Respiratory Arrest.

The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.

Seizures

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Seizures.

Due to general central nervous system stimulation, therapy with CNS stimulant drugs may cause seizures. These drugs may lower the convulsive threshold in patients with history of seizures, with prior electroencephalogram (EEG) abnormalities without seizures, and very rarely, without history of seizures and no prior EEG evidence of seizures. Therapy with CNS stimulants should be used with caution in patients with or predisposed to seizures. If seizures occur, therapy should be discontinued.

Moderate:

pimozide

Pimozide has a moderate potential interaction with Seizures.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Tachyarrhythmia

Moderate:

CVS Extra Strength Headache Relief

The caffeine in CVS Extra Strength Headache Relief has a moderate potential interaction with Tachyarrhythmia.

Like other methylxanthines, caffeine at high dosages may be associated with positive inotropic and chronotropic effects on the heart. Caffeine may also produce an increase in systemic vascular resistance, resulting in elevation of blood pressure. Therapy with products containing caffeine should be administered cautiously in patients with severe cardiac disease, hypertension, hyperthyroidism, or acute myocardial injury. Some clinicians recommend avoiding caffeine in patients with symptomatic cardiac arrhythmias and/or palpitations and during the first several days to weeks after an acute myocardial infarction.

Tardive Dyskinesia

Moderate:

pimozide

Pimozide has a moderate potential interaction with Tardive Dyskinesia.

Tardive dyskinesia (TD) has occurred in patients treated with antipsychotic drugs; the syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk appears highest in older patients (particularly older women) but it is not possible to predict which patients are likely to develop TD; whether antipsychotic drugs differ in their potential to cause TD is unknown. The risk of TD and the likelihood that it will become irreversible increase with the duration of therapy and the total cumulative dose. The syndrome can develop after relatively brief treatment periods, even at low dosages; it may also occur after discontinuation of therapy. TD may remit (partially or completely) upon discontinuation of antipsychotic therapy, although antipsychotic therapy itself may suppress (or partially suppress) signs/symptoms of TD, possibly masking the underlying process; the effect of symptomatic suppression on the long-term course of TD is unknown. In patients with preexisting drug-induced TD, initiating or increasing the dosage of antipsychotic therapy may temporarily mask the symptoms of TD but could eventually worsen the condition. In patients requiring chronic therapy, the lowest dose and shortest duration of therapy producing a satisfactory clinical response are recommended; the need for continued therapy should be reassessed periodically. If signs/symptoms of TD occur during antipsychotic therapy, discontinuation of the offending agent should be considered; however, some patients may require treatment despite the presence of TD.

Thrombocytopathy

Major:

CVS Extra Strength Headache Relief

The aspirin in CVS Extra Strength Headache Relief has a major potential interaction with Thrombocytopathy.

The use of aspirin is contraindicated in patients with significant active bleeding or hemorrhagic disorders such as hemophilia, von Willebrand's disease, or telangiectasia. Aspirin interferes with coagulation by irreversibly inhibiting platelet aggregation and prolonging bleeding time. The non-aceylated salicylates (i.e. salicylate salts such as sodium or magnesium salicylate) do not demonstrate these effects and may be appropriate substitutions in these patients. However, all salicylates can interfere with the action of vitamin K and induce a dose-dependent alteration in hepatic synthesis of coagulation factors VII, IX and X. At usual recommended dosages, a slight increase in prothrombin time (PT) may occur. Therapy with salicylates, especially aspirin, should be administered with extreme caution in patients with hypoprothrombinemia, vitamin K deficiency, thrombocytopenia, thrombotic thrombocytopenic purpura, severe hepatic impairment, or anticoagulant use.

Thrombocytopenia

Tic Disorder

Major:

pimozide

Pimozide has a major potential interaction with Tic Disorder.

Pimozide is contraindicated in the treatment of simple tics or tics other than those associated with Tourette's Disorder.

Urinary Retention

Moderate:

pimozide

Pimozide has a moderate potential interaction with Urinary Retention.

Most neuroleptic agents have anticholinergic activity, to which elderly patients are particularly sensitive. Clozapine and low- potency agents such as chlorpromazine and thioridazine tend to exhibit the greatest degree of anticholinergic effects in the class, while haloperidol as well as the newer, atypical agents like quetiapine, risperidone and ziprasidone have generally been associated with very low frequencies of anticholinergic adverse effects. Therapy with neuroleptic agents should be administered cautiously 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.

Varicella-Zoster

Major:
