In addition, Clozaril treatment was associated with categorical increases in serum total cholesterol and triglyceride, as illustrated in Table 6. The proportion of patients with categorical increases in total cholesterol or fasting triglyceride increased with the duration of exposure. The median duration of Clozaril and chlorpromazine exposure was 45 days and 38 days, respectively. The Clozaril dose range was 100 mg to 900 mg daily; the maximum chlorpromazine dose was 1800 mg daily.

These effects may be worse if you take it with alcohol or certain medicines. Use Clozaril with caution. Do not drive or perform other possibly unsafe tasks while you take Clozaril.
Cognitive and motor performance may be impaired. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. NMS can recur. Monitor closely if restarting treatment with antipsychotics. Using this medicine with any of the following may cause an increased risk of certain side effects but may be unavoidable in some cases. If used together, your doctor may change the dose or how often you use this medicine, or give you special instructions about the use of food, alcohol, or tobacco.

Pulmonary embolism and deep-vein thrombosis have occurred in patients treated with clozapine. Consider the possibility of pulmonary embolism in patients who present with deep-vein thrombosis, acute dyspnea, chest pain, or with other respiratory signs and symptoms.

Clozapine Orally Disintegrating Tablets. A hematology consultation may be useful in deciding to rechallenge a patient. In general, however, do not rechallenge patients who develop severe neutropenia with Clozapine Orally Disintegrating Tablets or a clozapine product. Antipsychotic drugs including Clozaril can cause a potentially fatal symptom complex referred to as Neuroleptic Malignant Syndrome NMS. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status, and autonomic instability irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmias. Associated findings can include elevated creatine phosphokinase CPK myoglobinuria, rhabdomyolysis, and acute renal failure. Appropriate studies have not been performed on the relationship of age to the effects of clozapine in the pediatric population. Safety and efficacy have not been established. Benign ethnic neutropenia BEN is a condition observed in certain ethnic groups whose average ANC values are lower than “standard” laboratory ranges for neutrophils. It is most commonly observed in individuals of African descent approximate prevalence of 25-50% some Middle Eastern ethnic groups, and in other non-Caucasian ethnic groups with darker skin. BEN is more common in men. Patients with BEN have normal hematopoietic stem-cell number and myeloid maturation, are healthy, and do not suffer from repeated or severe infections. They are not at increased risk for developing clozapine-induced neutropenia. Additional evaluation may be needed to determine if baseline neutropenia is due to BEN. Consider hematology consultation before initiating or during Clozapine Orally Disintegrating Tablets treatment as necessary. In managing overdosage, consider the possibility of multiple-drug involvement. Immune System Disorders: Angioedema, leukocytoclastic vasculitis. Use one-third of the Clozapine Orally Disintegrating Tablets dose. Monitor neonates for symptoms of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding difficulties.

NMS has occurred with clozapine monotherapy and with concomitant CNS-active medications, including lithium. The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone GnRH resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients. Faltus F, Hynek V, Dolezalova V et al.

TD and are considered the drugs of choice in patients being treated for psychosis. Postmarketing, very rare events of ventricular tachycardia, cardiac arrest, and QT prolongation which may be associated with Torsades de pointes have been observed, although there is no conclusive causal relationship to use of this drug. Clozaril is indicated for the treatment of severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment. The manufacturers recommend appropriate clinical monitoring, including baseline and periodic follow-up lipid evaluations, in patients receiving clozapine. Manufacturers recommend clinical monitoring of weight during therapy. 1 395 400 406 See Hyperglycemia and Diabetes Mellitus under Cautions.

Effects may be dose-related; consider dosage reduction in patients experiencing such effects. 1 See Advice to Patients. Tardive dyskinesia TD has occurred in patients treated with antipsychotic drugs, including Clozaril. The syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk of TD and the likelihood that it will become irreversible are believed to increase with greater durations of treatment and higher total cumulative doses. However, the syndrome can develop after relatively brief treatment periods at low doses. Prescribe Clozaril in a manner that is most likely to minimize the risk of developing TD. Use the lowest effective dose and the shortest duration necessary to control symptoms. Periodically assess the need for continued treatment. Consider discontinuing treatment if TD occurs. However, some patients may require treatment with Clozaril despite the presence of the syndrome. C until time of use. 395 Protect from moisture.

There was significantly greater use of concomitant psychotropic medications among the patients in the olanzapine group.
