Prochlorperazine — Uses, Dosage, Side Effects & Safety

Drug class: Antipsychotic, Antiemetic (Phenothiazine derivative)

Overview

Prochlorperazine is a medication used to treat severe nausea and vomiting, vertigo, and sometimes schizophrenia or anxiety. It belongs to a group of medicines called phenothiazines, which work by blocking dopamine receptors in the brain to help control symptoms. This drug is commonly prescribed for short-term relief of nausea and vomiting caused by various conditions, including migraine, post-operative recovery, or chemotherapy. It may also be used to manage dizziness (vertigo) and, less frequently, certain mental health disorders. Patients should know that prochlorperazine can cause drowsiness and should be used exactly as prescribed. It is important to avoid driving or operating heavy machinery until you know how the medication affects you. Always inform your healthcare provider about any other medicines you are taking and any medical conditions you have.
