It is not recommended to have intercourse after putting the pessary, otherwise it may cause drug malabsorption and local infection, which may aggravate the condition and make the condition persist. 1, drug malabsorption: the drug absorption time of pessary varies from person to person, the drug stays in the vagina during the medication period and is not completely absorbed by the body, if intercourse will not only affect the drug absorption rate, reduce the therapeutic effect, but also cause discomfort. 2. Infection: Povidon suppositories are mainly used for the treatment of cervical erosion, senile vaginitis, mycotic vaginitis and other diseases. When the medication is used, the patients themselves are infected and intercourse may cause bleeding and aggravation of local infection, which is not conducive to recovery. In addition, it may cause damage to male genitalia and cross-infection. If you are using a medication such as Povidone-Pill which is placed in the vagina for treatment, intercourse is not recommended during use and can wait until the disease has fully recovered. It is important to wash the vulva and vagina with water before using the pessary, to lie down as much as possible after using the pessary so that the medication can have the best effect, and to review the pessary on time after the treatment has improved. The side effects of Povidon suppositories are rare, but a few patients may experience fever, chills, pain, allergies, etc. If necessary, seek medical attention for treatment. In addition, patients should also pay attention to a light diet, avoid sitz baths, ensure personal hygiene, and if necessary, disinfect the items to prevent cross-infection.
