What should be used to treat a skin allergy?

To effectively treat a skin allergy, hydrocortisone is commonly used due to its anti-inflammatory properties. Hydrocortisone helps reduce redness, swelling, and itching associated with allergic reactions on the skin. It is a corticosteroid that works by suppressing the immune response that causes these symptoms, making it particularly effective for treating various inflammatory skin conditions, such as dermatitis or allergic reactions.

Creams and lotions can also provide relief and hydration to the skin but do not specifically address the underlying inflammatory response as effectively as hydrocortisone does. Antibiotics are used to treat bacterial infections, not allergies, so they would not be appropriate in this context. Thus, hydrocortisone is the recommended treatment for a skin allergy because it directly targets the inflammation and discomfort caused by the allergic reaction.
