What is the treatment for a mild allergic reaction?

In cases of a mild allergic reaction, oral antihistamines are the appropriate treatment as they specifically target allergy symptoms such as itching, hives, and nasal congestion. Antihistamines work by blocking the action of histamine, a substance in the body that causes allergic symptoms. They are effective for managing mild allergic reactions without the need for more aggressive treatments.

Adrenaline injections are reserved for severe allergic reactions, such as anaphylaxis, where immediate life-saving measures are required. Corticosteroid injections are typically used for more severe or prolonged symptoms or conditions, not for mild reactions. Cold compresses can provide symptomatic relief for itching or swelling but do not address the underlying allergic response and are not considered a standard treatment for the reaction itself. Thus, oral antihistamines are the most suitable choice for effectively managing mild allergic reactions.
