Hives, also known as urticaria, are red, itchy, and sometimes painful welts that appear on the skin. They can be caused by various factors, including allergies, infections, and physical stimuli. For many people, hives can be a source of significant discomfort and distress. Fortunately, there are several effective over-the-counter (OTC) antihistamines available that can provide relief from hives. This article will explore the strongest OTC antihistamines for hives, their mechanisms of action, and how they compare to each other.
Understanding Hives
Hives are a common allergic reaction that occurs when the body releases histamine in response to an allergen. Histamine causes blood vessels to dilate, leading to redness, swelling, and itching. Hives can appear suddenly and may last for a few hours to several days. In some cases, they can become chronic, lasting for more than six weeks.
