The ANC is usually available as a component of the complete blood count (CBC), including differential, and is more relevant to drug-induced neutropenia than is the white blood cell (WBC) count. You may report side effects to Health Canada at 1-866-234-2345. MEANINGFUL RECOVERY from Schizophrenia and Serious Mental Illness with Clozapine: Hope & Help by Dr. Laitman and others.It sounds like you desperately need another doctor for your son. Clozapine: (Moderate) The anticholinergic activity of clozapine may interfere with the action of cholinergic medications such as galantamine. The risk is highest during the initial titration period, particularly with rapid dose-escalation. Use caution when coadministering clozapine with other drugs that are metabolized by CYP2D6.

The clozapine dose should be increased to the original dose when coadministration of strong CYP1A2 inhibitors is discontinued Moderate or weak CYP1A2 inhibitors include oral contraceptives and caffeine. However, some patients may require treatment with clozapine despite the presence of the syndrome.There is no known treatment for TD. After coadministration of fluvoxamine for 14 days, mean trough concentrations of clozapine and its metabolites, In a study of schizophrenic patients (n=14) who received clozapine under steady-state conditions, coadministration of paroxetine produced only minor changes in the levels of clozapine and its metabolites. Mean Changes in Total Cholesterol and Triglyceride Concentration in Studies in Adult Subjects with SchizophreniaTable 6. Therapeutic drug monitoring should occur to account for individual variation (4, 6). By mouth. Monitor weight during treatment with clozapine. Patients must have had a Clinical Global Impressions – Severity Scale score of at least 4 (moderately ill).In the prospective, lead-in phase of the trial, all patients (N=305) initially received single-blind treatment with haloperidol (the mean dose was 61 mg per day) for 6 weeks. Hypersalivation is a well-documented side effect of clozapine that may affect nearly 30% of patients who take this medication. These reactions can occur with the first dose, at doses as low as 12.5 mg. The mechanism for this increased risk is not known. BEN is more common in men. Consider hematology consultation before initiating or during clozapine treatment as necessary.Patients with BEN require a different ANC algorithm for clozapine management due to their lower baseline ANC levels. You may report side effects to the FDA at 1-800-FDA-1088. You may report side effects to FDA at 1-800-FDA-1088.In Canada - Call your doctor for medical advice about side effects.

Use caution when administering Clozapine tablets to patients with a history of seizures or other predisposing risk factors for seizure (CNS pathology, medications that lower the seizure threshold, alcohol abuse). This was a prospective, randomized, open-label, active-controlled, multicenter, international, parallel-group comparison of clozapine versus olanzapine (ZyprexaDosing regimens for each treatment group were determined by individual investigators and were individualized by patient. Concomitant strong CYP1A2 inhibitors (eg, fluvoxamine, ciprofloxacin, or enoxacin): reduce clozapine dose by ⅓.

Maintenance dose: 16 to 24 mg per day given in 2 divided doses Maximum dose: 24 mg/day Extended release capsule: Initial dose: 8 mg orally once a day, preferably with the morning meal-After 4 weeks, dose should be increased to 16 mg once a day, a further increase to 24 mg once a day may be considered after a minimum of 4 weeks of taking 16 mg/day Categorical Changes in Fasting Glucose Level in Studies in Adult Subjects with SchizophreniaTable 5.

• The medication is started at a low dose and then slowly increased to the most suitable dose for that person, depending on the response to the treatment. After that year my son’s voices and delusions were almost non existent. Updated The maximum dose is 900 mg per day. Reduce the clozapine dose to one-third of the original dose when clozapine is coadministered with strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin, or enoxacin). Consider the possibility of NMS Pulmonary embolism and deep-vein thrombosis have occurred in patients treated with clozapine.

Use caution when treating patients at risk for significant electrolyte disturbance, particularly hypokalemia. I know that 1 drop in ANC is not usually a concern but more than 1 drop is a big concern. Subsequent dose increases can be in increments of up to 100 mg once or twice weekly. It is most commonly observed in individuals of African descent (approximate prevalence of 25 to 50%), some Middle Eastern ethnic groups, and in other non-Caucasian ethnic groups with darker skin. Clozapine should be used with caution in patients with risk factors for cerebrovascular adverse reactions.If abrupt discontinuation of clozapine is necessary (because of severe neutropenia or another medical condition, for example) The following adverse reactions are discussed in more detail in other sections of the labeling:Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.The most commonly reported adverse reactions (≥ 5%) across clozapine clinical trials were: CNS reactions, including sedation, dizziness/vertigo, headache, and tremor; cardiovascular reactions, including tachycardia, hypotension, and syncope; autonomic nervous system reactions, including hypersalivation, sweating, dry mouth, and visual disturbances; gastrointestinal reactions, including constipation and nausea; and fever. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.

Avoid concomitant use of clozapine with anticholinergic drugs when possible Use caution when administering concomitant medications that prolong the QT interval or inhibit the metabolism of clozapine.

If a patient's ANC remains equal to or greater than 1500/μL for the first 6 months of treatment, monitoring frequency may be reduced to every 2 weeks for the next 6 months.
