69 potential interactions Applies to: 38 conditions, including High Blood Pressure, Depression, Type 2 Diabetes, Bipolar Disorder, and Anxiety and Stress.

Alcoholism

Major:

doxepin

Doxepin has a major potential interaction with Alcoholism.

Tricyclic antidepressants (TCAs), can lower the seizure threshold and trigger seizures. These drugs should be used with extreme caution in patients with a history of seizures, or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism. Daily dose restrictions might apply for specific antidepressants. Physicians are encouraged to get additional dosing recommendations on the manufacturer's prescribing information.

Major:

mazindol

Mazindol has a major potential interaction with Alcoholism.

CNS stimulants (especially amphetamines) have a high potential for abuse and misuse, which can lead to development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants can result in overdose and death; this risk is increased with higher doses or unapproved methods of administration (e.g., snorting, injection). Before prescribing a CNS stimulant, each patient's risk for abuse, misuse, and addiction should be assessed. Throughout therapy, it is recommended to reassess each patient's risk and frequently monitor for signs/symptoms of abuse, misuse, and addiction. Therapy with CNS stimulants should be administered cautiously, if at all, in patients with a history of alcohol or substance abuse. The use of some agents is contraindicated in patients with a history of drug abuse.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Alcoholism.

Tricyclic antidepressants can enhance the response to alcohol. In patients who may use alcohol excessively, it should be borne in mind that the potentiation may increase the danger inherent in any suicide attempt or overdosage.

Anxiety and Stress

Major:

mazindol

Mazindol has a major potential interaction with Anxiety and Stress.

Some CNS stimulants are contraindicated in patients with marked agitation and/or anxiety since these symptoms may be aggravated. CNS stimulants may also exacerbate symptoms of behavior disturbance and thought disorder in psychotic patients, particularly children. Therapy with CNS stimulants should be administered cautiously in patients with a history of psychosis or a predisposition to agitated states.

Arrhythmia

Major:

doxepin

Doxepin has a major potential interaction with Arrhythmia.

Tricyclic and tetracyclic antidepressants (TCAs) may cause orthostatic hypotension, reflex tachycardia, syncope, and dizziness, particularly during initiation of therapy or rapid escalation of dosage. Imipramine appears to have the greatest propensity to induce these effects, while secondary amines such as nortriptyline may do so less frequently. Tolerance to the hypotensive effects often develops after a few doses to a few weeks. Rarely, collapse and sudden death have occurred secondary to severe hypotension. Other reported adverse cardiovascular effects include tachycardia, arrhythmias, heart block, hypertension, thrombosis, thrombophlebitis, myocardial infarction, strokes, congestive heart failure, and ECG abnormalities such as PR and QT interval prolongation. Therapy with TCAs should be avoided during the acute recovery phase following myocardial infarction, and should be administered only with extreme caution in patients with hyperthyroidism, a history of cardiovascular or cerebrovascular disease, or a predisposition to hypotension. Close monitoring of cardiovascular status, including ECG changes, is recommended at all dosages. Many of the newer antidepressants, including bupropion and the selective serotonin reuptake inhibitors (SSRIs), are considerably less or minimally cardiotoxic and may be appropriate alternatives.

Bipolar Disorder

Moderate:

doxepin

Doxepin has a moderate potential interaction with Bipolar Disorder.

Tricyclic antidepressants (TCAs) may aggravate symptoms of psychosis in schizophrenic patients, particularly those with paranoid symptomatology. Depressed patients, usually those with bipolar disorder, may experience a switch from depression to mania or hypomania. These occurrences have also been reported rarely with the tetracyclic antidepressant, maprotiline. Therapy with these agents should be administered cautiously in patients with schizophrenia, bipolar disorder, or a history of mania.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Bipolar Disorder.

A major depressive episode can be the initial presentation of bipolar disorder. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder prior to initiating treatment with a tricyclic antidepressant. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that tricyclic antidepressants are not approved for use in treating bipolar depression.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Bipolar Disorder.

A major depressive episode can be the initial presentation of bipolar disorder. Patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder prior to initiating treatment with doxepin. This screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that doxepin is not approved for use in treating bipolar depression.

Bone Marrow Depression/Low Blood Counts

Moderate:

doxepin

Doxepin has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.

The use of tricyclic and tetracyclic antidepressants (TCAs) has rarely been associated with bone marrow suppression. Leukopenia, agranulocytosis, thrombocytopenia, anemia, eosinophilia, purpura, and pancytopenia have been reported with some TCAs. Patients with preexisting bone marrow suppression or blood dyscrasias receiving TCAs should be monitored closely during therapy for further decreases in blood counts.

Cardiovascular Conditions and Disorders

Depression

Major:

doxepin

Doxepin has a major potential interaction with Depression.

A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of most anxiolytics, sedatives and hypnotics. Some of these changes include decreased inhibition, aggressiveness, agitation, and hallucinations. These drugs can cause or exacerbate mental depression and cause suicidal behavior and ideation. Therapy with these drugs should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.

Major:

mazindol

Mazindol 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.

Diabetes Mellitus

Moderate:

doxepin

Doxepin has a moderate potential interaction with Diabetes Mellitus.

There have been reports of both elevation and lowering of blood sugar levels in patients receiving tricyclic antidepressants. These drugs should be used with caution in patients with hypoglycemia, hyperglycemia or diabetes. Monitoring sugar levels is recommended.

Moderate:

doxepin

The use of some agents is contraindicated in patients with a history of drug abuse.

Gastrointestinal Obstruction

Major:

doxepin

Doxepin has a major potential interaction with Gastrointestinal Obstruction.

Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs 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. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.

Glaucoma, Narrow Angle

Moderate:

doxepin

Doxepin has a moderate potential interaction with Glaucoma, Narrow Angle.

Tricyclic antidepressants as other type of antidepressants have an effect on pupil size causing dilation. This effect can potentially narrow the eye angle resulting in increased intraocular pressure and angle closure glaucoma, especially in predisposed patients. These drugs should be used with caution in patients with anatomically narrow angle or history of glaucoma. Doxepin hydrochloride capsules are contraindicated in patients with glaucoma.

Glaucoma/Intraocular Hypertension

Major:

doxepin

Doxepin has a major potential interaction with Glaucoma/Intraocular Hypertension.

Liver Disease

Moderate:

doxepin

Doxepin has a moderate potential interaction with Liver Disease.

Tricyclic and tetracyclic antidepressants (TCAs) are known to undergo metabolism in the liver. Some of the metabolites, such as those of imipramine, clomipramine and desipramine, may be pharmacologically active. Many of the metabolites are also excreted by the kidney. There are very limited data concerning the use of TCAs in patients with renal and/or liver disease. Therapy with TCAs should be administered cautiously in patients with significantly impaired renal or hepatic function. Dosage adjustments may be necessary.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Liver Disease.

In general, tricyclic antidepressants should be used with caution in patients with liver or renal disease, as these drugs are metabolized and excreted through the liver and kidneys. Dose selection, especially in the elderly patients that might have liver or renal dysfunction, should usually be limited to the smallest effective total daily dose. Some tricyclic antidepressants such as clomipramine and nortriptyline have occasionally been associated with elevations in SGOT (AST) and SGPT (ALT), and other hepatic adverse events such as jaundice. Although serious liver injury has only been reported rarely, therapy with these drugs should be administered cautiously in patients with preexisting liver disease and periodic monitoring of liver enzyme levels is recommended.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Liver Disease.

Some anxiolytics, sedatives and hypnotics are extensively metabolized by the liver, and excreted in the urine. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects, including central nervous system and respiratory depression, due to drug and metabolite accumulation. Therapy with these drugs should be administered cautiously in such patients, with careful dose selection usually starting at the low end of the dosing range.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Liver Disease.

In general, anxiolytics, sedatives and hypnotics 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 these drugs should be administered cautiously in patients with liver disease (some are not recommended in severe liver impairment), and the dosage should be adjusted accordingly. Laboratory testing is recommended prior and during treatment.

Moderate:

mazindol

Mazindol 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.

Mania

Moderate:

doxepin

Doxepin has a moderate potential interaction with Mania.

Tricyclic antidepressants (TCAs) may aggravate symptoms of psychosis in schizophrenic patients, particularly those with paranoid symptomatology. Depressed patients, usually those with bipolar disorder, may experience a switch from depression to mania or hypomania. These occurrences have also been reported rarely with the tetracyclic antidepressant, maprotiline. Therapy with these agents should be administered cautiously in patients with schizophrenia, bipolar disorder, or a history of mania.

Neurosis

Major:

mazindol

Mazindol has a major potential interaction with Neurosis.

Some CNS stimulants are contraindicated in patients with marked agitation and/or anxiety since these symptoms may be aggravated. CNS stimulants may also exacerbate symptoms of behavior disturbance and thought disorder in psychotic patients, particularly children. Therapy with CNS stimulants should be administered cautiously in patients with a history of psychosis or a predisposition to agitated states.

Neutropenia

Moderate:

doxepin

Doxepin has a moderate potential interaction with Neutropenia.

The use of some tricyclic antidepressants has been associated with neutropenia (ANC < 500/mm3) and agranulocytosis (ANC < 500/mm3). Leukocyte and differential blood counts should be performed in patients that develop fever and sore throat during treatment. Therapy should be discontinued if there is evidence of pathologic neutrophil depression.

Peripheral Arterial Disease

Major:

mazindol

Mazindol 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.

Pheochromocytoma

Major:

doxepin

Doxepin has a major potential interaction with Pheochromocytoma.

Tricyclic and tetracyclic antidepressants (TCAs) may potentiate the effects of circulating catecholamines. Enhanced sympathetic activity can provoke hypertensive crises in patients with pheochromocytoma or other tumors of the adrenal medulla, such as some neuroblastomas. Therapy with TCAs should be administered cautiously in patients with these tumors.

Major:

mazindol

Mazindol 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. 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.

Psychosis

Major:

mazindol

Mazindol 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.

Major:

mazindol

Mazindol has a major potential interaction with Psychosis.

Some CNS stimulants are contraindicated in patients with marked agitation and/or anxiety since these symptoms may be aggravated. CNS stimulants may also exacerbate symptoms of behavior disturbance and thought disorder in psychotic patients, particularly children. Therapy with CNS stimulants should be administered cautiously in patients with a history of psychosis or a predisposition to agitated states.

Renal Dysfunction

Moderate:

doxepin

Doxepin has a moderate potential interaction with Renal Dysfunction.

Some anxiolytics, sedatives and hypnotics are extensively metabolized by the liver, and excreted in the urine. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects, including central nervous system and respiratory depression, due to drug and metabolite accumulation. Therapy with these drugs should be administered cautiously in such patients, with careful dose selection usually starting at the low end of the dosing range.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Renal Dysfunction.

In general, tricyclic antidepressants should be used with caution in patients with liver or renal disease, as these drugs are metabolized and excreted through the liver and kidneys. Dose selection, especially in the elderly patients that might have liver or renal dysfunction, should usually be limited to the smallest effective total daily dose. Some tricyclic antidepressants such as clomipramine and nortriptyline have occasionally been associated with elevations in SGOT (AST) and SGPT (ALT), and other hepatic adverse events such as jaundice. Although serious liver injury has only been reported rarely, therapy with these drugs should be administered cautiously in patients with preexisting liver disease and periodic monitoring of liver enzyme levels is recommended.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Renal Dysfunction.

Tricyclic and tetracyclic antidepressants (TCAs) are known to undergo metabolism in the liver. Some of the metabolites, such as those of imipramine, clomipramine and desipramine, may be pharmacologically active. Many of the metabolites are also excreted by the kidney. There are very limited data concerning the use of TCAs in patients with renal and/or liver disease. Therapy with TCAs should be administered cautiously in patients with significantly impaired renal or hepatic function. Dosage adjustments may be necessary.

Moderate:

mazindol

Mazindol 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.

Schizophrenia

Moderate:

doxepin

Doxepin has a moderate potential interaction with Schizophrenia.

Some tricyclic antidepressants have shown to cause activation or exacerbation of psychosis in schizophrenic patients. A dosage reduction might be required.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Schizophrenia.

Tricyclic antidepressants (TCAs) may aggravate symptoms of psychosis in schizophrenic patients, particularly those with paranoid symptomatology. Depressed patients, usually those with bipolar disorder, may experience a switch from depression to mania or hypomania. These occurrences have also been reported rarely with the tetracyclic antidepressant, maprotiline. Therapy with these agents should be administered cautiously in patients with schizophrenia, bipolar disorder, or a history of mania.

Seizures

Moderate:

mazindol

Mazindol 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.

Tardive Dyskinesia

Moderate:

doxepin

Doxepin has a moderate potential interaction with Tardive Dyskinesia.

Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. As with other drugs that possess anticholinergic activity, TCAs may aggravate tardive dyskinesia or induce previously suppressed symptoms. Patients with tardive dyskinesia requiring therapy with TCAs should be monitored for exacerbation of the condition.

Tic Disorder

Major:

mazindol

Mazindol has a major potential interaction with Tic Disorder.

CNS stimulants have been reported to worsen Tourette's syndrome and exacerbate motor and verbal tics. Before initiating therapy, it is recommended to assess family history and clinically evaluate patients for tics or Tourette's syndrome. Therapy with CNS stimulants, if necessary, should be administered cautiously in patients with tic disorders or family history of Tourette's syndrome. The manufacturers of the CNS stimulants, methylphenidate (racemic) and dexmethylphenidate (the more pharmacologically active d-enantiomer), consider their use to be contraindicated in such patients.

Type 2 Diabetes

Moderate:

mazindol

Mazindol has a moderate potential interaction with Type 2 Diabetes.

Obese, type 2 diabetic patients who achieve weight loss may demonstrate improved metabolic control of their disease as a result of their reduced weight. Therefore, patients with type 2 diabetes mellitus should be monitored during weight-reduction therapy (or therapy that may be expected to induce significant weight loss as a secondary effect) for hypoglycemia and reduced need for oral hypoglycemic medication or insulin, and the dosages of these agents adjusted accordingly. Patients should be apprised of the risk of hypoglycemia and be alert to potential signs and symptoms such as headache, dizziness, drowsiness, nervousness, confusion, tremor, hunger, weakness, perspiration, and palpitation.

Urinary Retention

Major:

doxepin

Doxepin has a major potential interaction with Urinary Retention.

Tricyclic and tetracyclic antidepressants (TCAs) have anticholinergic activity, to which elderly patients are particularly sensitive. Tertiary amines such as amitriptyline and trimipramine tend to exhibit greater anticholinergic effects than other agents in the class. Therapy with TCAs 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. In patients with angle-closure glaucoma, even average doses can precipitate an attack. Glaucoma should be treated and under control prior to initiation of therapy with TCAs, and intraocular pressure monitored during therapy.

Major:

doxepin

Doxepin has a major potential interaction with Urinary Retention.

The use of doxepin is contraindicated in patients with glaucoma, or a tendency to urinary retention. These disorders should be ruled out before starting treatment, especially in elderly patients.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Urinary Retention.

Due to their anticholinergic properties, tricyclic antidepressants should be administered with caution in patients with history of urinary retention. Particularly doxepin hydrochloride capsules are contraindicated in patients with tendency to urinary retention.

Moderate:

doxepin

Doxepin has a moderate potential interaction with Urinary Retention.

Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
