It is not recommended to use Povidon suppositories during menstruation, because they may not achieve the therapeutic effect when used during menstruation and will be discharged from the vagina with menstrual blood. During the menstrual period, pay attention to keep the vulva clean and hygienic. After the menstrual period, you can apply povidone pessary vaginally for 1-2 consecutive courses of medication, and prohibit sexual intercourse during the medication period. The pessary is a gynecological drug that can be used for symptoms such as increased discharge and vulvar itching caused by damp heat, as well as for the treatment of gynecological diseases caused by mycosis fungoides and viral infections. When using the medicine, women may also experience symptoms such as vaginal itching or vaginal discharge, most of which are caused by drug stimulation, so pay attention to washing the vulva.
