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 DM is a combination medicine containing the drugs promethazine and dextromethorphan. It's used to treat coughing, runny nose, and sneezing caused by the common cold, allergies, hay fever, and other illnesses. Promethazine is a phenothiazine, which blocks the effects of histamines (natural substances that cause allergy symptoms). Dextromethorphan is a cough suppressant that acts on a certain part of the brain to reduce the urge to cough. The Food and Drug Administration (FDA) first approved the medicine in 1957.
