Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Altered Consciousness
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Altered Consciousness.
The use of phenothiazines is contraindicated in comatose patients and patients with severe central nervous system depression. Phenothiazines may potentiate the CNS and respiratory depression in these patients.
Arrhythmia
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Arrhythmia.
Phenothiazines may cause hypotension. Patients with pheochromocytoma, cerebral vascular or renal insufficiency, cardiovascular disease, or a severe cardiac reserve deficiency (e.g., mitral insufficiency) may be more prone to hypotensive reactions. Close monitoring is recommended during treatment if used in at-risk patients; some products may be contraindicated (e.g., thioridazine). Large doses and parenteral administration should be used cautiously, or avoided, in patients with impaired cardiovascular systems.
Major:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Bone Marrow Depression/Low Blood Counts
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Phenothiazines may cause hematologic toxicity. In patients with preexisting blood dyscrasias, bone marrow suppression, or a history of drug-induced leukopenia or neutropenia, phenothiazines should not be used or are contraindicated. Complete blood counts should be regularly monitored in patients with risk factors for blood dyscrasias. If white blood cell counts indicate cellular depression, discontinue treatment and institute appropriate therapy.
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Breast Cancer
Moderate:

The amitriptyline in amitriptyline / perphenazine 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:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Mania
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Neuroleptic Malignant Syndrome
Moderate:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a moderate potential interaction with Neuroleptic Malignant Syndrome.
Therapy with phenothiazines may precipitate or aggravate a potentially fatal symptom complex known as neuroleptic malignant syndrome (NMS). Treatment should not be initiated in patients with active NMS, and should be immediately discontinued if currently administered in such patients. In patients with a history of NMS, introduction or reintroduction of phenothiazines should be carefully considered, since NMS may recur.
Neutropenia
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Pheochromocytoma
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Pheochromocytoma.
Phenothiazines may cause hypotension. Patients with pheochromocytoma, cerebral vascular or renal insufficiency, cardiovascular disease, or a severe cardiac reserve deficiency (e.g., mitral insufficiency) may be more prone to hypotensive reactions. Close monitoring is recommended during treatment if used in at-risk patients; some products may be contraindicated (e.g., thioridazine). Large doses and parenteral administration should be used cautiously, or avoided, in patients with impaired cardiovascular systems.
Major:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Renal Dysfunction
Moderate:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a moderate potential interaction with Renal Dysfunction.
Phenothiazines should be used with caution in patients with renal dysfunction. Patients with renal insufficiency may be more prone to hypotension. Periodic renal function tests are recommended for all patients during prolonged therapy.
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.

Respiratory Arrest
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Respiratory Arrest.
The use of phenothiazines is contraindicated in comatose patients and patients with severe central nervous system depression. Phenothiazines may potentiate the CNS and respiratory depression in these patients.
Schizophrenia
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Seizures
Moderate:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a moderate potential interaction with Seizures.
Phenothiazines can lower the seizure threshold. Caution is recommended during administration in patients with a history of convulsive disorders or EEG abnormalities. Anticonvulsant therapy should be maintained or adequately adjusted during phenothiazine treatment.
Syncope
Major:
flibanserin
Flibanserin has a major potential interaction with Syncope.
The use of flibanserin can cause hypotension and syncope. The benefits and risks of therapy should be considered in patients with preexisting conditions that predispose to hypotension. Flibanserin should be used with caution in these patients.
Tardive Dyskinesia
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Urinary Retention
Major:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Moderate:
amitriptyline / perphenazine
The amitriptyline in amitriptyline / perphenazine 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.
Valvular Heart Disease
Major:
amitriptyline / perphenazine
The perphenazine in amitriptyline / perphenazine has a major potential interaction with Valvular Heart Disease.
Phenothiazines may cause hypotension. Patients with pheochromocytoma, cerebral vascular or renal insufficiency, cardiovascular disease, or a severe cardiac reserve deficiency (e.g., mitral insufficiency) may be more prone to hypotensive reactions. Close monitoring is recommended during treatment if used in at-risk patients; some products may be contraindicated (e.g., thioridazine). Large doses and parenteral administration should be used cautiously, or avoided, in patients with impaired cardiovascular systems.
