Types of urticaria

Acute urticaria is commonly caused by foods, drugs, infections and insect bites. Common foods that cause urticaria include nuts, chocolate, fish, eggs, tomatoes, berries, milk, food additives and preservatives.

Sometimes urticaria is caused by physical factors such as sunlight, heat, cold, exercise, pressure and even vibrations (physical urticaria). Some people may get hives that form after stroking or scratching the skin, known as " dermatographism ", but are otherwise healthy.

Urticaria lasting more than six weeks is termed chronic urticaria. Your dermatologist may need to ask you many questions to make a diagnosis and help find the cause, though sometimes the exact cause may not be identified. There are no specific tests for urticaria, but certain tests may be suggested depending on your history and examination findings.

How to treat urticaria

Where the cause of urticaria can be identified, avoidance of the trigger is the most effective form of management. Antihistamines may be prescribed by your dermatologist to provide relief, and often work best if taken on a regular schedule to prevent hives from forming. No one antihistamine works best for everyone, so more than one antihistamine or different combinations may have to be tried and tested to find the one that works best for you.

In certain urticaria refractory to combinations of antihistamines, a short course of oral corticosteroid medications may have to be used to control the swelling.
