Hives (Urticaria)

Hives, or urticaria, present as raised, itchy wheals that may appear suddenly and move around the body. Individual lesions typically resolve within 24 hours, although new ones may continue to develop. Acute urticaria often follows infection or an allergic trigger, while chronic urticaria can persist for months without a clear external cause. Management focuses on symptom control, usually with non-sedating antihistamines, and identifying potential triggers where possible.

• Note how long episodes have been occurring.

• Consider possible triggers, including infections, medication changes or foods.

• Bring a list of antihistamines tried and the doses used.

Photographs of the rash can be helpful, as lesions may not be visible at the time of review.
