For different diseases of the ear, different drops are used, as follows: 1. For simple otitis externa or otitis media, you can use Telbital ear drops for topical application, which has a good anti-inflammatory effect; 2. If the inflammation is caused by eczema or allergy in the external ear canal, you need to use ear drops containing hormones, or eye drops for topical application, in order to achieve relief and treatment. If the inflammation is serious, in addition to local medication, you also need to use antibiotics orally for symptomatic treatment, and some serious symptoms also need infusion treatment. 3. If the inflammation is caused by purulent otitis media, you also need to use hydrogen peroxide for cleaning before using Telbital ear drops, which will have a better effect.
