Phenergan is a medication that contains the active ingredient promethazine. It is commonly used to relieve symptoms of various conditions such as allergies, motion sickness, nausea, and vomiting. Promethazine works by blocking histamine, which is a natural substance in your body that causes allergic symptoms. This medication is suitable for adults and children over 2 years old who need relief from these symptoms.
