The maximum usage of povidone iodine solution is a few days, and there is no clear regulation. It should be determined according to one's own situation. However, this medication cannot be used for a long time, and should be stopped promptly after the skin improves.
Povidone iodine solution is a topical medication mainly used for disinfecting skin and mucosal wounds. When the skin is injured by external force, this drug can be used to diminish inflammation and kill bacteria, which can promote the skin recovery to a certain extent. For small area of mild burns or scalds, it can also promote the healing and prevent infection. At the same time, it can also improve the corresponding symptoms caused by suppurative dermatitis and skin fungal infectious diseases. At present, there is no medical research indicating that povidone iodine solution can be used for a maximum of a few days, but it should not be used for a long time, otherwise it can easily lead to drug resistance. If the skin develops resistance and then shows lesions again, the use of this drug cannot achieve therapeutic effects and it is difficult to control the disease.
Povidone iodine solution can be applied to the skin using a cotton swab dipped in a small amount of liquid. After application, some people may experience slight irritation and pain in the local area, and generally do not require special treatment or improvement. It can disappear on its own after a period of time. Povidone iodine solution cannot be taken orally as it may cause drug poisoning reactions after oral administration. It must be placed at a relatively high place to avoid contact with children.
