What is chlorpromazine?

Chlorpromazine is an anti-psychotic medication in a group of drugs called phenothiazines (FEEN-oh-THYE-a-zeens). It works by changing the actions of chemicals in your brain.

Chlorpromazine is used to treat psychotic disorders such as schizophrenia or manic-depression, and severe behavioral problems in children ages 1 through 12.

Do not take chlorpromazine if you have recently used large amounts of alcohol or taken a medicine that makes you sleepy.
