You should not use potassium permanganate baths for mycosis vaginalis. The acidic environment in the vagina is too high, which can lead to the growth of mycobacteria, because mycobacteria tend to grow in an acidic environment. Potassium permanganate is an acidic drug and if you use an acidic lotion to wash your vulva, it will aggravate the growth of mycobacteria. If you want to inhibit the growth of mycobacteria, you need to use alkaline lotions such as sodium bicarbonate for vaginal douching or diluted sitz baths to promote recovery, or you can use antifungal medications in the vagina such as clotrimazole suppositories and dacrynic acid suppositories. Mycosis vaginalis is easily spread through sexual intercourse. During the treatment period, it is better not to have intercourse, change underwear regularly, and eat a light diet without spicy and stimulating food to help recovery.
