Progesterone soft capsules should be placed in the vagina at a depth of about 9-10 cm, preferably in the posterior vaginal vault, where the drug will melt under the action of vaginal secretions and body temperature and be absorbed by the vaginal mucosa to exert certain therapeutic effects, and can be used for the treatment of anorectic abortion. In addition, it is not recommended to put progesterone soft capsules into the vagina in case of preterm abortion and vaginal bleeding, but to take them orally. Progesterone soft capsules can also be placed into the vagina to treat shortened menstrual cycles due to progesterone deficiency or irregular vaginal bleeding in the second half of the menstrual period, and can be placed into the posterior vaginal fornix to achieve progesterone supplementation through mucosal absorption, thus restoring menstruation to a normal state. It is important to wash the vulva and put on a finger cover before placing the pill to avoid infection.
