Summary
Chlorpromazine is used to treat mental health conditions like schizophrenia, which is a disorder affecting a person's ability to think, feel, and behave clearly, and bipolar disorder, which involves extreme mood swings. It also helps with severe nausea and vomiting.
Chlorpromazine works by blocking certain chemicals in the brain, which helps reduce symptoms like hallucinations, which are false perceptions, and agitation, which is a state of nervous excitement.
The usual starting dose for adults is 25 mg taken 2 to 4 times daily. The maximum dose is typically 1000 mg per day. It can be taken with or without food, and the dose may be lower for children or the elderly.
Common side effects include drowsiness, which is feeling sleepy, dry mouth, which is a lack of saliva, and constipation, which is difficulty in passing stools. These effects vary among individuals and are generally mild.
Chlorpromazine should not be used if you have allergies to it or severe liver disease. Avoid alcohol, as it increases drowsiness. It can interact with other medications, so always inform your doctor about all drugs you are taking.
