The health care prescriber will decide on the best treatment, and will consider factors including symptoms experienced, current medical conditions, medications already being taken, and potential side effects that a new medication might cause.
Side effects vary from person to person and are not always the same for everyone.
People taking CLOZARIL might experience one or more of the following side effects:
AGRANULOCYTOSIS
Fever, weakness, infection symptoms
ORTHOSTATIC HYPOTENSION, BRADYCARDIA, & SYNCOPE
Low blood pressure, feeling faint, slow heart rate, and loss of consciousness
SEIZURES
MYOCARDITIS AND CARDIOMYOPATHY
Inflammation or enlargement of the heart
INCREASED RISK OF DEATH IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
In addition to agranulocytosis (the most serious side effect associated with CLOZARIL), the following side effects have been reported:
CLOZARIL® (clozapine) is an atypical antipsychotic indicated for:
WARNING: SEVERE NEUTROPENIA; ORTHOSTATIC HYPOTENSION, BRADYCARDIA, AND SYNCOPE; SEIZURE; MYOCARDITIS AND CARDIOMYOPATHY; INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS
See full prescribing information for complete boxed warning.
Most common adverse reactions (≥5%) were: CNS reactions (sedation, dizziness/vertigo, headache, and tremor); cardiovascular reactions (tachycardia, hypotension, and syncope); autonomic nervous system reactions (hypersalivation, sweating, dry mouth, and visual disturbances); gastrointestinal reactions (constipation and nausea); and fever.
To report SUSPECTED ADVERSE REACTIONS, contact HLS at (844) 457-8721; or FDA at (800) FDA-1088 or https://www.fda.gov/medwatch.Required Laboratory Testing Prior to Initiation and During Therapy
Re-Initiation of Treatment
Anticholinergic Toxicity – When possible, avoid use with other anticholinergic drugs and use with caution in patients with a current diagnosis or prior history of constipation, urinary retention, clinically significant prostatic hypertrophy, or other conditions in which anticholinergic effects can lead to significant adverse reactions.
Cognitive and Motor Performance (Interference) – Advise caution when operating machinery, including automobiles.
Eosinophilia – Assess for organ involvement (e.g., myocarditis, pancreatitis, hepatitis, colitis, nephritis). Discontinue if these occur.
Fever – Evaluate for infection and for neutropenia, or NMS.
Gastrointestinal Hypomotility with Severe Complications: – Severe gastrointestinal adverse reactions have occurred with the use of CLOZARIL. If constipation is identified, close monitoring and prompt treatment is advised.
Hepatotoxicity – Can be fatal. Monitor for hepatotoxicity. Discontinue treatment if hepatitis or transaminase elevations combined with other symptoms occur.
Metabolic Changes – Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include:
Neuroleptic Malignant Syndrome (NMS) – Immediately discontinue and monitor closely. Assess for co-morbid conditions.
Pulmonary Embolism (PE) – Consider PE if respiratory distress, chest pain, or deep vein thrombosis occur.
QT Interval Prolongation – Can be fatal. Consider additional risk factors for prolonged QT interval (disorders and drugs).
Nursing Mothers: Discontinue drug or discontinue nursing, taking into consideration importance of drug to mother.
Pneumonia and other Inflammatory Conditions – Published case reports describe examples where pneumonia or other inflammatory conditions may increase clozapine concentrations. The clinical significance, the impact of treatments to modulate this inflammation, and mechanism of this potential increase in clozapine concentrations have not been fully characterized but may involve reduced cytochrome P450 1A2 activity.
