Do you need to use alcohol to remove iodine when treating paronychia with iodine tincture?

Iodine tincture is commonly used as a disinfectant in the treatment of paronychia due to its strong antibacterial properties. Whether or not alcohol should be used to remove residual iodine after application mainly depends on the specific circumstances. 1. Effect of iodine tincture: Iodine tincture is an alcohol solution containing iodine, which has antibacterial and disinfecting effects and can be effective in treating paronychia. 2. Necessity of deiodination: The alcohol component in iodine tincture gives it certain penetrating ability; however, if deiodination is not performed, residual iodine may cause skin irritation, burning sensation, and peeling. 3. Methods of deiodination: If deiodination is required after using iodine tincture, it is recommended to use 75% medical-grade alcohol. In the absence of alcohol, rinsing with clean water can also achieve a deiodination effect. After using iodine tincture to treat paronychia, deiodination is recommended to prevent skin irritation and damage caused by residual iodine. During deiodination, either alcohol or water can be chosen based on the actual situation.
