About Promethazine

Promethazine is one of the most versatile and widely used medications in Nigeria, functioning as an antihistamine, anti-nausea agent, cough suppressant, and sedative all in one. It belongs to the phenothiazine class of first-generation antihistamines and works by blocking histamine H1 receptors throughout the body, which is responsible for its anti-allergy effects. Unlike newer second-generation antihistamines such as cetirizine and loratadine, promethazine readily crosses the blood-brain barrier, which accounts for its pronounced sedative effect. This sedation, while considered a side effect in many contexts, is actually one of the primary reasons promethazine is so popular in Nigeria — it is frequently used as a sleep aid and calming agent. Best known by its brand names Phenergan and Avomine, promethazine is stocked in virtually every pharmacy and patent medicine store from the busy Idumota market area in Lagos to neighbourhood chemists in Enugu, Kaduna, and Maiduguri.
