Allersoothe® | Allersoothe (Promethazine hydrochloride) - 10mg (50 tablets)

Allersoothe (Promethazine hydrochloride) is a phenothiazine in the same class of drugs as chlorpromazine (Thorazine) and trifluoperazine (Stelazine); however, unlike the other drugs in this class, promethazine is not used clinically as an anti-psychotic. It acts as an anti-histamine, a sedative, and an anti-emetic (anti-nausea). Promethazine is used principally as an anti-emetic, to prevent motion sickness or as an anti-histamine in combination with other medications in cough and cold preparations. Allersoothe (Promethazine hydrochloride) was approved by the FDA in 1951.
