Promethazine is a first-generation phenothiazine antihistamine. It blocks histamine H1 receptors to reduce allergic responses and also exerts anticholinergic, sedative, and antiemetic (anti-nausea) effects. The “Plain” version from PAI Pharma contains only promethazine (no added codeine or dextromethorphan, unlike some combination products like Promethazine DM).
It is prescription-only and used for short-term symptom relief.
