Phenergan® Syrup contains promethazine HCl, a prescription medicine used under medical supervision to relieve allergy symptoms such as sneezing, runny nose, itching, and watery eyes. It may also be used to control nausea and vomiting, as advised by a healthcare professional.
It works by blocking histamine and other chemical mediators in the body, helping reduce allergic reactions and providing relief from discomfort. The syrup formulation allows easy administration, especially for children or adults who prefer liquid medicine.
