FazaClo Oral

FazaClo Oral Warning

While clozapine can provide great benefits, it can rarely cause serious, possibly fatal side effects. For this reason, clozapine is used when other treatments have not worked or you cannot take them.

This medication can cause a serious immune system problem called agranulocytosis (low white blood cells). To make sure you have enough white blood cells, you will need to have a blood test before you begin taking clozapine and then have your blood tested regularly during your treatment. (See also How to Use, Side Effects, and Notes sections.)

Clozapine can also cause seizures, especially in higher doses. Let your doctor or pharmacist know if you have ever had seizures. While taking this medication, avoid driving or other activities during which a sudden loss of consciousness could be dangerous (e.g., operating heavy machinery, swimming).

This medication may rarely cause an inflammation of the heart muscle (myocarditis). Seek immediate medical attention if you have weakness, difficult/rapid breathing, chest pain, or swelling of the ankles/legs. Your risk is highest in the first month of treatment.

Clozapine can cause a big drop in blood pressure, which can make you dizzy or cause you to faint when you stand up. Be sure to get up slowly while taking this medication. This is more likely to occur when your dose of clozapine is increased or if you are also taking a benzodiazepine (e.g., clonazepam, lorazepam, diazepam).

There may be a slightly increased risk of serious, possibly fatal side effects (e.g., stroke, heart failure) when this medication is used in elderly patients with dementia. Discuss the risks and benefits of this medication, as well as other effective and possibly safer treatments for dementia-related behavior problems, with your doctor.

FazaClo Oral Side Effects

Drooling, drowsiness, dizziness, headache, shaking (tremor), vision problems (e.g., blurred vision) and constipation may occur. Many of these effects (especially drowsiness) lessen as your body gets used to the medication. If any of these effects persist or worsen, contact your doctor or pharmacist promptly.

To prevent constipation, maintain a diet adequate in fiber, drink plenty of water, and exercise. If you become constipated while using this drug, consult your pharmacist for help in selecting a laxative (e.g., stimulant-type with stool softener).
