Chlorpromazine is a typical antipsychotic medication from the phenothiazine class. It is commonly used to treat psychiatric disorders like bipolar disorder, schizophrenia, and severe behavioral problems. Chlorpromazine acts on the dopamine receptors in the brain by blocking them, which helps to alleviate symptoms of psychosis and stabilize mood.

Special Considerations for Chlorpromazine
● Pregnancy: Classified as FDA Category C, chlorpromazine should be used during pregnancy only if the benefits justify the potential risks, especially in the third trimester due to possible effects on the fetus.
● Liver Health: Careful monitoring is required for patients with liver issues, as chlorpromazine is metabolized by the liver and could cause liver damage or jaundice.
● Kidney Health: Although no significant dose adjustments are needed for kidney function, patients with severe renal impairment should be closely monitored.
