What is the first treatment tried for hives?

Hives, also called urticaria, are raised itchy areas that can appear and fade as skin cells release histamine. An oral antihistamine blocks histamine activity, which can calm itch and limit new welts. It does not identify every possible trigger, and it may not be the right choice for someone with certain health conditions or medication interactions.

Use the medicine exactly as directed by a clinician or its labelled instructions. Ask about an option that is less likely to cause drowsiness if you need to drive or work. Cool compresses, loose clothing, and avoiding a suspected trigger may make the skin more comfortable. If symptoms continue, return often, or interfere with sleep, a clinician may review the diagnosis and consider another treatment such as oral corticosteroid therapy for selected situations.

Get emergency help for swelling of the lips, tongue, or throat, trouble breathing, faintness, or difficulty swallowing. These symptoms can signal a severe allergic reaction and need urgent attention. Arrange medical review when hives are widespread, keep recurring without an obvious trigger, or come with fever, bruising, painful lesions, or other new symptoms.

Which antihistamine fits my age, health conditions, and other medicines? How long should I try it before checking back? Could a food, medicine, infection, heat, pressure, or another exposure be contributing? What symptoms mean I should seek urgent help?
