What medication and dose would you administer for a mild allergic reaction with itching in an adult?

Treating a mild allergic reaction with itching centers on blocking the effects of histamine to relieve itching and hives. Diphenhydramine is an H1 antihistamine that reduces itching, urticaria, and overall allergic symptoms. The adult dose commonly used is 25–50 mg taken by mouth, repeated every 4–6 hours as needed. Epinephrine is reserved for more dangerous reactions with airway involvement or shock (anaphylaxis) and isn’t indicated for a mild, non-severe reaction. Acetaminophen targets fever and pain, not histamine-driven itching. An albuterol inhaler addresses bronchospasm, not cutaneous itching or hives unless there’s concurrent wheezing or asthma symptoms.
