Can potassium permanganate cause fetal malformations?

Under normal circumstances, potassium permanganate does not cause fetal malformations, but it should be used only as directed by a physician; blind use of the drug is not recommended. The specific analysis is as follows:

Potassium permanganate is a strong oxidizing agent and a commonly used topical antiseptic. If a pregnant woman experiences symptoms such as vulvar itching or abnormal vaginal discharge, soaking baths with diluted potassium permanganate may help improve these conditions, which typically do not affect the fetus. However, the medication must be diluted with lukewarm water before use, and soaking time should not be too long to avoid irritating the skin of the vulva.

Potassium permanganate is corrosive. When using it, care must be taken not to irrigate inside the vagina, to prevent mucosal irritation or burns.
