Acute Alcohol Intoxication
Major:
chlorpromazine
chlorproMAZINE has a major potential interaction with Acute Alcohol Intoxication.
Phenothiazines are contraindicated in the presence of large amounts of central nervous system depressants such as alcohol. The risk of suicide and the danger of overdose may be increased in patients who use alcohol excessively. Phenothiazines should be used with caution in patients experiencing alcohol withdrawal.
Alcoholism
Major:
chlorpromazine
chlorproMAZINE has a major potential interaction with Alcoholism.
Phenothiazines are contraindicated in the presence of large amounts of central nervous system depressants such as alcohol. The risk of suicide and the danger of overdose may be increased in patients who use alcohol excessively. Phenothiazines should be used with caution in patients experiencing alcohol withdrawal.
Altered Consciousness
Major:
chlorpromazine
chlorproMAZINE 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:

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.
Bone Marrow Depression/Low Blood Counts
Major:
chlorpromazine
chlorproMAZINE 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.
Breast Cancer
Moderate:
chlorpromazine
chlorproMAZINE has a moderate potential interaction with Breast Cancer.
The chronic use of phenothiazines is associated with persistent elevations in prolactin levels. The clinical significance in patients with a history of breast cancer is unknown and should be considered prior to therapy; approximately one-third of human breast cancers are thought to be prolactin-dependent. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in animal studies; however, evidence is inconclusive in humans.
Cardiovascular Conditions and Disorders
Major:

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.
Central Nervous System Disorders
Moderate:

Cerebrovascular Insufficiency
Major:
chlorpromazine
chlorproMAZINE has a major potential interaction with Cerebrovascular Insufficiency.
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.
Dementia
Major:
chlorpromazine
chlorproMAZINE 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.
Glaucoma/Intraocular Hypertension
Moderate:
chlorpromazine
chlorproMAZINE has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Phenothiazines have anticholinergic activity, which may cause mydriasis. Caution is recommended in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as glaucoma. Older patients may be particularly sensitive.

chlorproMAZINE 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.
