Whether or not iodophor can be used for ear infections depends on different situations, as follows: 1. Yes: If there is a certain degree of congestion and swelling or breakage in the shallow part of the external ear canal, then iodophor swabs can be used appropriately for disinfection treatment. 2. No: If there is a deeper area in the external ear canal or an acute inflammatory infection in the middle ear, then iodophor is not suitable for anti-inflammatory treatment. In addition to local treatment, patients should also take oral or intravenous antibiotic anti-infection treatment, such as penicillin or cephalosporin antibiotics. In some patients with serious congestion and swelling in the ear canal, Chinese medicines with detoxifying and anti-swelling effects can be used in combination, such as Liushen capsules.
