How Diphenhydramine Injection Works

Diphenhydramine is a first-generation antihistamine (H1-receptor antagonist). It blocks the action of histamine—a chemical responsible for allergic symptoms—helping to relieve swelling, itching, hives, and airway constriction. When administered by injection, it acts rapidly in the bloodstream, making it ideal for emergencies.
