Most mosquito bites stop itching and heal on their own in a few days. These self-care tips from the Mayo Clinic may make you more comfortable.
Apply a lotion, cream or paste. Putting calamine lotion or nonprescription hydrocortisone cream on the bite can help ease the itch. Or try dabbing the bite with a paste made of baking soda and water. Reapply several times daily until your symptoms go away.
Apply a cool compress. Try soothing the bite by applying a cold pack or a cool, moist cloth for a few minutes
Take an oral antihistamine. For stronger reactions, try taking a nonprescription antihistamine (Benadryl, Chlor-Trimeton, others).
