Promethazine is an antihistamine used to treat allergy symptoms, nausea, vomiting, and motion sickness. It works by blocking histamine receptors in the brain, which helps reduce allergic reactions and calm nausea. Promethazine is also used as a sedative for short-term treatment of insomnia and in combination with other medications for pain management.
