Side Effects List Clozaril side effects by likelihood and severity. Sassim N, Grohmann R. Adverse drug reactions with clozapine and simultaneous application of benzodiazepines. Pharmacopsychiatry. QT prolongation, Torsade de Pointes and other life-threatening ventricular arrhythmias, cardiac arrest, and sudden death have occurred with Clozaril treatment. When prescribing Clozaril, consider the presence of additional risk factors for QT prolongation and serious cardiovascular reactions. Conditions that increase these risks include the following: history of QT prolongation, long QT syndrome, family history of long QT syndrome or sudden cardiac death, significant cardiac arrhythmia, recent myocardial infarction, uncompensated heart failure, treatment with other medications that cause QT prolongation, treatment with medications that inhibit the metabolism of clozapine, and electrolyte abnormalities.
Consider hematology consultation. Consider hematology consultation. 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 Clozaril-induced neutropenia. Additional evaluation may be needed to determine if baseline neutropenia is due to BEN. Consider hematology consultation before initiating or during Clozaril treatment as necessary. Use caution when administering Clozaril to patients with a history of seizures or other predisposing risk factors for seizure CNS pathology, medications that lower the seizure threshold, alcohol abuse.

Neutropenia reported in clozapine-treated patients. Our clients include Sanofi and CEVA etc. Clozapine is primarily metabolized by CYP isoenzymes 1A2, 2D6, and 3A4. If manifestations of hyperglycemia occur in any patient, perform fasting blood glucose testing. 1 331 332 See Advice to Patients. Seizures have occurred with clozapine treatment. The risk is dose-related.
The information contained in the Truven Health Micromedex products as delivered by Drugs. Clozapine Orally Disintegrating Tablets are only available through a restricted program under a REMS called the Clozapine REMS Program because of the risk of severe neutropenia. See Tables 1 and 2 for ANC monitoring frequency and treatment recommendations based on ANC value in the general patient population and for patients with BEN, respectively. Clinical electroencephalogram EEG studies demonstrated that clozapine increases delta and theta activity and slows dominant alpha frequencies. Enhanced synchronization occurs. Sharp wave activity and spike and wave complexes may also develop. Patients have reported an intensification of dream activity during clozapine therapy. REM sleep was found to be increased to 85% of the total sleep time. In these patients, the onset of REM sleep occurred almost immediately after falling asleep. No specific pharmacokinetic studies were conducted to investigate the effects of renal or hepatic impairment on the pharmacokinetics of clozapine. Higher clozapine plasma concentrations are likely in patients with significant renal or hepatic impairment when given usual doses. Metabolized by many CYP isoenzymes, particularly 1A2, 2D6, and 3A4. 1 320 May inhibit CYP2D6. mectizan
Clozapine-related eosinophilia has also occurred in the absence of organ involvement and can resolve without intervention. There are reports of successful rechallenge after discontinuation of clozapine, without recurrence of eosinophilia. In the absence of organ involvement, continue Clozaril under careful monitoring. If the total eosinophil count continues to increase over several weeks in the absence of systemic disease, the decision to interrupt Clozaril therapy and rechallenge after the eosinophil count decreases should be based on the overall clinical assessment, in consultation with an internist or hematologist.

For the 956 patients who received clozapine or olanzapine in this study, there was extensive use of concomitant psychotropics: 84% with antipsychotics, 65% with anxiolytics, 53% with antidepressants, and 28% with mood stabilizers. There was significantly greater use of concomitant psychotropic medications among the patients in the olanzapine group. Low blood pressure, slow heartbeat, fainting, and heart attack have occurred with the use of Clozaril. The risk is highest when the dose is being increased, especially if it is increased too fast. These reactions can occur with any dose of Clozaril. Take Clozaril as directed by your doctor.

Tardive dyskinesia TD has occurred in patients treated with antipsychotic drugs, including clozapine. 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 Clozapine Orally Disintegrating Tablets 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 Clozapine Orally Disintegrating Tablets despite the presence of the syndrome. After coadministration of fluvoxamine for 14 days, mean trough concentrations of clozapine and its metabolites, N-desmethylclozapine and clozapine N-oxide, were elevated about 3-fold compared to baseline steady-state concentrations.

Use with caution in the presence of narrow-angle glaucoma, concomitant anticholinergic medications, prostatic hypertrophy, or other conditions in which anticholinergic effects can lead to significant adverse reactions. Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP3A4, and CYP2D6. Use caution when administering Clozapine Orally Disintegrating Tablets concomitantly with drugs that are inducers or inhibitors of these enzymes. Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics including clozapine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. However, epidemiological studies suggest an increased risk of treatment-emergent, hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. Precise risk estimates for hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics are not available. Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.

Most patients were Caucasian 71% 15% were Black, 1% were Asian, and 13% were classified as being of “other” races. It is unclear if concurrent use of other drugs known to cause neutropenia increases the risk or severity of Clozaril-induced neutropenia. There is no strong scientific rationale to avoid Clozaril treatment in patients concurrently treated with these drugs.

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.
