Can Zapine cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. Your doctor will discuss the risks of the treatment with you before you start taking Zapine. In particular, Zapine can cause heart problems and blood disorders. You will be given regular check-up appointments so that your doctor can monitor you for any evidence of these.
The table below contains some of the most common unwanted effects associated with Zapine. You will find a full list in the manufacturer's information leaflet supplied with your medicine.
Zapine, also sold under the brand name Clozaril, is an older (i.e. “typical”) antipsychotic medication prescribed to treat neuropsychiatric conditions such as schizophrenia and schizoaffective disorder. Although many people find Zapine to be highly effective for reducing symptoms of their psychiatric disorders, other individuals may find the drug to be intolerable or lacking in efficacy. Any person who doesn’t respond well to Zapine might end up discontinuing treatment, yet when treatment is over, Zapine withdrawal symptoms typically occur.

Information on Zapine
Zapine (marketed as Clozaril, Fazaclo ODT, Versacloz and generics) is an antipsychotic medicine used to treat schizophrenia in patients whose symptoms are not controlled with standard antipsychotic drugs. Zapine is also used in patients with recurrent suicidal behavior associated with schizophrenia or schizoaffective disorder.
While Zapine is beneficial for some patients, there are risks associated with this drug. Specifically, Zapine can decrease the number of neutrophils, a type of white blood cell, that function in the body to fight off infections. When neutrophils are significantly decreased, severe neutropenia may result and the body may become prone to infections. For this reason, patients taking Zapine need to have their absolute neutrophil count (ANC) monitored on a regular basis. This monitoring requirement serves as the basis for the Zapine Risk Evaluation and Mitigation Strategy (REMS).
- Available only through a restricted program called the Zapine REMS
- Severe neutropenia, defined as an absolute neutrophil count (ANC) less than 500/mm³, has been reported
- Severe neutropenia can lead to serious infection and death
- Prior to initiating treatment, a baseline ANC must be 1500/mm³ or greater for the general population and 1000/mm³ or greater for patients with documented benign ethnic neutropenia
- Regularly monitor ANC during treatment
- Advise patients to immediately report symptoms consistent with severe neutropenia or infection (e.g., fever, weakness, lethargy, sore throat)
- Caution with history of seizure or other factors predisposing to seizure
- Risk is dose-related
Myocarditis, Cardiomyopathy, and Mitral Valve Incompetence
- Fatal myocarditis and cardiomyopathy reported; discontinue and obtain cardiac evaluation if suspected
- Measuring brainNP levels may offer a means of monitoring to detect early, asymptomatic myocarditis
- Do not re-challenge patients with history of Zapine-associated myocarditis or cardiomyopathy
- Dizziness upon standing (orthostatic hypotension), slow heart rate (bradycardia), fainting (syncope), and cardiac arrest may occur
- Risk is highest during initial titration period, particularly with rapid dose escalation
- May occur with the first dose, and with doses as low as 12.5 mg/day
- Caution with history of cardiovascular or cerebrovascular disease or conditions predisposing to low blood pressure (hypotension)
Increased mortality in elderly with dementia-related psychosis
- Not approved for dementia-related psychosis; patients with dementia-related psychosis who are treated with antipsychotic drugs are at increased risk of death, as shown in short-term controlled trials; deaths in these trials appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature
