Medicines listed for Allergic States

The four products on this page contain Promethazine, Prednisone, prednisolone and methylprednisolone, all supplied as tablets. Promethazine is an antihistamine that can ease symptoms such as itching, hives and a runny nose during an allergic reaction. Prednisone, prednisolone and methylprednisolone belong to the corticosteroid group, which works by dampening the immune system’s overreaction to allergens. The listed strengths span 4 mg to 40 mg across the three steroid options, and 25 mg for the antihistamine.
