Can erythromycin ointment be used for mosquito bites?

Whether erythromycin ointment can be used after a mosquito bite depends on the specific circumstances. If there is no secondary infection, such as symptoms like redness, swelling, or pus formation, erythromycin ointment generally is not recommended, as it has no therapeutic effect on simple mosquito bites. At this time, antipruritic medications such as paeonol cream or calamine lotion can be used to relieve itching and swelling. If skin damage occurs due to scratching or other reasons following a mosquito bite and symptoms of bacterial infection appear, such as significant redness, pain, and exudation, then erythromycin ointment may be used for anti-infective treatment. As an antibiotic, erythromycin ointment has antibacterial and anti-inflammatory properties and can effectively alleviate infection symptoms.
