To place progesterone capsules vaginally, it is usually required to insert them into the deepest part of the vagina. Wash your hands and trim your fingernails before inserting them to avoid scratching the lateral wall of the vagina, which may cause damage to the mucosal tissue and result in bleeding and thus infection. Wash the vulva and insert the progesterone capsule along the lateral wall of the vagina into the posterior vaginal fornix, then gently withdraw your finger. If there is no foreign body sensation, it means that it has been put into the vagina, which is conducive to the absorption of progesterone soft capsule. It is usually recommended that progesterone soft capsule be inserted vaginally preferably while sleeping, so as not to stand up and walk around, which may cause the drug to be discharged and affect the absorption of the drug, thus affecting the therapeutic effect of the disease. During the medication period, it is important to maintain emotional stability, eat a light diet, and pay attention to the hygiene of the perineum to avoid bacterial growth and infection.
