If your baby has otitis media, you should not put hydrogen peroxide drops into the ear at will. Hydrogen peroxide is very stimulating and may sometimes cause the patient’s ear canal mucous membrane to become congested and inflamed. It is advisable to take the child to the hospital for a careful examination. If the eardrum is only slightly congested, oxyfloxacin ear drops or levofloxacin ear drops can be used. If the child’s eardrum is perforated and pus is flowing, you can consider having the doctor clean the pus inside the ear canal with hydrogen peroxide. After cleaning it, you need to rinse it again with saline to reduce the stimulation of the mucous membrane of the ear canal by hydrogen peroxide, and then apply antibiotics to reduce inflammation, and the situation of otitis media will improve significantly after active symptomatic treatment.
