Povidon suppositories can treat HPV high-risk infections and can treat vaginitis and cervicitis, as well as viral infections. At the same time, when there is HPV high-risk infection, it is not recommended to use the medicine directly because it is necessary to exclude which infection is present and whether there are any abnormal symptoms before using the Povidon suppository. When there is contact bleeding, frequent leucorrhea abnormalities, and HPV 16 and 18 infections, it is first recommended to have a colposcopic cervical biopsy to rule out any chance of precancerous lesions in the cervix. If the results of the cervical biopsy indicate only chronic inflammation or low-grade intraepithelial neoplasia, it is benign and can be treated with vaginal pessaries of Povidone for a period of time. A course of treatment is 7-10 days for 3 months, and after 3 months, the HPV test can be repeated 3 days after menstruation to see if it has turned negative.
