Clozaril

Form.

Tablets: 25 milligrams,
Tablets: 100 milligrams.

No Prescription

Clozaril is prescribed in the management of psychotic disorders including schizophrenia.
Clozaril is given to help people with severe schizophrenia who have failed to respond to standard treatments. It is prescribed to help reduce the risk of suicidal behavior in people with schizophrenia. Clozaril is not a cure, but it can help some people return to more normal lives.

Dosage.

Clozaril is given once, twice, or three times daily. The dose often is increased slowly until the optimal dose is found. The full effects of Clozaril may not be seen until several weeks after treatment is begun.

ADULTS

Your doctor will carefully individualize your dosage and monitor your response regularly.

The usual recommended initial dose is half of a 25-mg tablet (12.5 mg) 1 or 2 times daily. Your doctor may increase the dosage in increments of 25 to 50 mg a day to achieve a daily dose of 300 to 450 mg by the end of 2 weeks. Dosage increases after that will be only once or twice a week and will be no more than 100 mg each time. Dosage is increased gradually because rapid increases and higher doses are more likely to cause seizures and changes in heart rhythm. The most you can take is 900 mg a day divided into 2 or 3 doses.

Your doctor will determine long-term dosage depending upon your response and results of the regular blood tests.

CHILDREN

Safety and efficacy have not been established for children up to 16 years of age.

Side Effects.

Among elderly patients with dementia-related psychosis, treatment with Clozaril is associated with an increased risk of death for unclear reasons. Clozaril is not approved for use in dementia-related psychosis.

Seizures have occurred in approximately 1 of every 20 to 30 persons receiving Clozaril . Patients receiving higher doses seem to be at higher risk.

Dizziness may occur in 1 of 5 persons taking Clozaril . In some cases this may be due to orthostatic hypotension, a marked decrease in blood pressure that occurs when going from a lying or sitting position to a standing position. The drop in blood pressure may lead to loss of consciousness or even cardiac and respiratory arrest. This reaction is more common during the first few weeks of therapy while the dose is increasing, when drug is stopped briefly, or when patients are taking benzodiazepines such as diazepam (Valium) or other anti-psychotic drugs.

The most common side effect of Clozaril is drowsiness.

Other side effects include:
- Fever;
- Headache;
- Increased Heart Rate;
- Increased Salivation;
- Low Blood Pressure;
- Tremor;

Clozaril has anticholinergic effects that interfere with the function of smooth muscles. This can lead to blurred vision and difficulty urinating (when there is enlargement of the prostate) due to effects on the muscles of the eye and bladder. Clozaril slows the intestine and leads to constipation in approximately 14% of patients. Paralysis of the intestinal muscles can lead to paralytic ileus, a condition in which the intestine stops working.

Clozaril also may cause extrapyramidal effects (sudden, often jerky, involuntary motions of the head, neck, arms, body, or eyes). Like other anti-psychotics, Clozaril also may cause tardive dyskinesia (potentially irreversible involuntary movements). The risk of such reactions appears to be lower with Clozaril than with older anti-psychotics, perhaps due to its weaker effects on dopamine type 2 receptors.
