After the pessary is placed in the vagina, it will dissolve under the action of vaginal secretions. After dissolving, part of the pessary will be absorbed and part of it will form a drug residue and be discharged from the vagina. It is recommended to keep the area clean during the use of the pessary and to pay attention to the hygiene of your hands during the pessary insertion process. It is recommended to change underwear regularly during the plugging period and not to have sex, because sex may cause the medication to be taken out of the body and reduce the amount and effectiveness of the medication.
