How can the active ingredient promethazine hydrochloride help me?
The active ingredient in Phenergan is promethazine hydrochloride, which is an antihistamine that belongs to a group of medicines known as phenothiazines. When you have an allergic reaction, your body creates a natural substance called histamine. Histamine sends signals around your body that trigger symptoms of allergy, such as a runny nose or watery eyes. Antihistamines work by blocking histamine, which prevents your symptoms so you won’t have to tolerate an allergic reaction.
