Phenergan 25mg (Promethazine Hydrochloride) tablets are designed to treat a range of conditions, including allergic reactions like hay fever and rashes, travel sickness and insomnia. As a drowsy antihistamine belonging to a group of medicines known as phenothiazines, it works by blocking histamine, the natural substance your body produces during an allergic reaction. This helps to reduce symptoms like itching, swelling and irritation. Phenergan also acts on the brain to promote relaxation, making it effective for relieving nausea caused by travel sickness and encouraging restful sleep.
