Hives, also known as urticaria, are red, itchy welts that appear on the skin due to an allergic reaction or other triggers. They can be acute (lasting less than six weeks) or chronic (lasting more than six weeks). Effective management of hives often involves using antihistamines, which work by blocking histamine, a chemical released by the immune system that causes itching and redness. This article will explore the best antihistamines for hives, their mechanisms of action, safety profiles, and suitability for long-term use.
Understanding Hives and Antihistamines
Hives occur when the immune system overreacts to allergens or other triggers, releasing histamine. This leads to symptoms like redness, swelling, and itching. Antihistamines are the first line of defense against hives, providing relief by blocking histamine receptors. They are classified into two generations:
First-Generation Antihistamines:These can cause significant drowsiness and are generally used for short-term relief.
Second-Generation Antihistamines:These are less likely to cause drowsiness and are suitable for long-term use.
