Urticaria

Urticaria, commonly known as hives, is a skin reaction characterized by raised, itchy, red or skin-colored welts that can appear suddenly anywhere on the body and often shift location within hours. It results from the release of histamine and other chemicals from mast cells in the skin, causing localized swelling and itching. Episodes can be acute, resolving within six weeks, or chronic, persisting for months or longer without an identifiable trigger. While usually not dangerous, hives can occasionally accompany a more severe allergic reaction requiring urgent care.

The most common symptoms include: Raised; itchy welts that vary in size and shape; redness or swelling of the skin; welts that move or change location. Early recognition is key to prompt diagnosis and effective treatment.

No, Urticaria is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Antihistamines are the primary treatment to relieve itching and reduce welt formation; with higher doses or combination antihistamines used for more persistent cases. Chronic urticaria unresponsive to antihistamines may require additional medications such as omalizumab; and severe allergic reactions with swelling of the airway require emergency epinephrine treatment.. Treatment should always be guided by a qualified Dermatology specialist. Do not self-medicate.

While Urticaria cannot always be fully prevented, several measures can reduce risk: Identifying and avoiding known triggers; keeping a symptom diary to detect patterns; managing stress.

Consult a Dermatology specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
