Promethazine is a phenothiazine derivative that acts primarily as an H1-receptor antagonist (antihistamine). It also provides anticholinergic, sedative, and antiemetic (anti-nausea) effects by influencing other receptors in the brain. The oral syrup form is easy to dose and commonly used for its multi-symptom relief. It is prescription-only and available in various bottle sizes (e.g., 473 mL).
