Adults can also get otitis media, for example, if the patient has inflammation of the mucosa of the ear canal, and if the inflammation is severe, it can involve the patient’s eardrum to become congested and inflamed. Sometimes patients with colds or sore throats and rhinitis can easily trigger inflammation of the eustachian tube, which can involve the middle ear cavity, with inflammatory exudate formation, and the patient’s ears will have an obvious feeling of stuffiness and swelling, even accompanied by tinnitus and hearing loss, which is also a case of having otitis media. Patients are advised to exercise more in their lives to enhance their resistance and avoid causing otitis media to form. In terms of treatment, patients can use levofloxacin hydrochloride ear drops to reduce inflammation. In terms of oral medication, patients can decide whether to apply antibiotics according to their condition. If the pain is obvious, cefradine capsules can be added. A clear allergy history is needed before using the medication.
