Suppositories used in gynecology to treat diseases should not be used during menstruation, they need to be inserted into the vagina for treatment. During menstruation, the opening of the uterus is slightly open and the menstrual blood flows all the time, which can easily nourish bacteria. If suppositories are used at the time of menstruation, it will increase the patient’s discomfort and also increase the risk of bleeding and infection, so it is not appropriate. It is therefore recommended to wait until after the menstruation clears before using these suppositories, which are usually used to treat vaginal inflammation, cervical disorders, etc. Although suppositories cannot be used during menstruation, oral medications and lotions can be used normally.
