It is recommended to insert the pessary into the posterior vaginal vagina at a depth of about 10 cm after washing the vulva every night before bedtime, where the medication will dissolve rapidly and take effect under the action of body temperature, playing an antiseptic role. It is mainly used to treat chronic inflammation of the cervix, candida vaginitis, trichomoniasis, bacterial vaginosis, etc. During the treatment with Povidon suppositories, after the clinical symptoms have completely disappeared, it is necessary to stop the medication for 3-7 days and go to the hospital for a corresponding examination to see if the original pathogenic bacteria have completely disappeared. In case of cervical inflammation, it is necessary to find out whether the cervix is still locally congested and edematous, and then decide whether to stop using the medication. It should be noted that when using Povidon suppositories, empty your bladder first and be sure to wash your hands and vulva to avoid causing bacterial infection and aggravating the condition. Application is prohibited for women within 12 weeks of pregnancy. If the weather becomes hot and the suppository becomes soft, do not be in a hurry, you can put the medicine in the refrigerator, or in the freezer, and freeze it for 5-10 minutes before using it, this change of appearance will not affect its efficacy.
