What is the first treatment tried for insect bites?

An insect bite can trigger a local immune reaction, causing a raised, itchy, red, or swollen area. The size and duration of the reaction vary with the insect, the bite site, and the person's sensitivity. Scratching can break the skin and allow bacteria to enter.

A cool compress and gentle cleansing are useful first steps. For more troublesome itch, oral antihistamine therapy may reduce the body's itch response. A topical corticosteroid may be considered for local inflammation when a clinician or pharmacist confirms it is appropriate for the site.

Wash the area gently, apply a cool compress, and keep nails short. Avoid squeezing the bite, applying household chemicals, or using a strong product near the eyes, lips, genitals, or broken skin without advice.

If a stinger is visible, it should be removed carefully without repeatedly pressing the surrounding skin. Take note of when the reaction began and whether it is spreading; that information helps a clinician distinguish a local bite reaction from infection or allergy.

Call emergency services for trouble breathing, swelling of the lips or tongue, faintness, widespread hives, or difficulty swallowing after a bite. Seek prompt medical review for rapidly expanding redness, increasing warmth, pus, fever, severe pain, or a bite near the eye.

Ask whether your reaction looks local or allergic, which antihistamine treatment is suitable, whether a topical corticosteroid is safe for the location, and what warning signs should prompt urgent help.
