The class of drugs used to treat allergic reactions is called antihistamines.
Your body releases substances called histamines which attach to cells in the body, causing them to swell and leak fluid. This results in common allergy symptoms such as itching, sneezing, runny nose, and watery eyes. Antihistamines help prevent or relieve allergy symptoms by preventing histamines from attaching to the cells and causing symptoms.
