Cause: Hives are raised, itchy welts on the skin that are often triggered by an allergic reaction. Common allergenic triggers include specific foods (e.g., nuts, shellfish), medications (e.g., antibiotics, aspirin), insect stings, or physical factors like cold, heat, or pressure.
Symptoms: Hives typically present as red, itchy bumps or welts on the skin that vary in size and shape. They can appear suddenly and may change in location and appearance over time.
Treatments: Antihistamines, both non-sedating and sedating, are the mainstay of hives treatment. Corticosteroids may be prescribed for severe or persistent cases. Identifying and avoiding the specific trigger is essential.
Prevention: Preventing hives involves identifying and avoiding the triggers. If a medication is the cause, alternative medications may be prescribed. For those with severe allergies, carrying an epinephrine auto-injector can be life-saving in case of anaphylaxis.
