Frequently Asked Questions

Can I take a higher dose of Risperidone if my symptoms don't improve?

No. Never increase the dose of Risperidone without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.

Why do I need regular blood tests on clozapine?

Clozapine can cause agranulocytosis — a life-threatening reduction in white blood cells that prevents the body from fighting infections. Mandatory weekly blood count monitoring allows early detection and immediate discontinuation if white cells fall dangerously low, preventing potentially fatal infections.
