DRUG CLASS AND MECHANISM: Promethazine is in a class of drugs called phenothiazines which also includes chlorpromazine, and trifluoperazine; however, unlike the other drugs in this class, promethazine is not used as an anti-psychotic but rather as an anti-histamine, sedative, antiemetic (anti-nausea), and cough suppressant.
Promethazine is an antihistamine and works by blocking a certain natural substance that your body makes during an allergic reaction. Its other effects (such as anti-nausea, calming, pain relief) may work by affecting other natural substances (such as acetylcholine) and by acting directly on certain parts of the brain.
