Introduction

Using 75% alcohol to relieve itching caused by urticaria may provide some temporary relief, but it does not treat the underlying condition itself. Urticaria is a skin disorder characterized primarily by symptoms such as redness, swelling, itching, and raised rashes. If symptoms are severe or persist for an extended period, it is advisable to seek medical attention promptly for appropriate evaluation and diagnosis to identify the cause and receive proper treatment.

Generally, 75% alcohol can be used to relieve itching caused by urticaria and may provide some symptomatic relief, but it does not treat the underlying condition itself. The detailed explanation is as follows:

Urticaria is a skin disorder primarily characterized by redness, swelling, itching, and papules. It is an allergic reaction marked by wheals—another term for erythematous edematous patches in the dermis—mainly due to localized increased blood flow. Applying alcohol to the skin causes evaporation, which helps dissipate body heat and thus alleviates itching and disperses wheals. However, this method is not suitable for individuals who are allergic to alcohol. It should be noted that alcohol application only provides symptomatic relief and does not address the body's allergic response. Treatment of urticaria should target its underlying cause, with common approaches including oral antihistamines, topical corticosteroids, and immunosuppressants. When using medications, it is essential to follow a doctor’s instructions regarding dosage and duration of treatment.

If the allergen can be identified, exposure should be avoided as much as possible. Daily bathing and maintaining clean skin can reduce bacterial growth and help alleviate symptoms. Avoid spicy, greasy, and irritating foods. Ensure adequate sleep and proper rest. If symptoms are severe or persist for an extended period, prompt medical consultation is recommended for appropriate examinations and diagnosis to determine the cause and initiate suitable treatment.
