If the otitis externa is a bacterial infection, cefuroxime is useful. If it is a fungal infection, cefuroxime is not useful.
Otitis externa is an inflammation of the skin and subcutaneous tissues of the external auditory canal caused by various reasons. According to the classification of pathogens, it can be categorized into bacterial and fungal infections, and bacterial infections are more common than fungal infections. Therefore, medication should be selected according to the type of pathogen in treatment.
Bacterial infections of otitis externa may be treated with topical antibiotics such as ciprofloxacin and glucocorticosteroids such as hydrocortisone in mild and moderate cases. Severe cases of otitis externa may require systemic antibiotics such as cefadroxil, cefuroxime, and ciprofloxacin. Cefuroxime is effective in this type of otitis externa.
For fungal otitis externa, in addition to thorough cleaning of the ear canal, antifungal medications such as gentian violet and mycotoxin should be used. This type of otitis externa is not effective with cefuroxime, or may lead to worsening of the condition. If accompanied by tympanic membrane perforation, the above drugs should be avoided and repeated rinsing and treatment should be done.
The above drugs should be used reasonably under the guidance of a doctor, and avoid buying drugs on your own.
