For vaginal use, it is recommended to clean your fingers, wash your vulva, insert the progesterone capsule along the lateral wall of the vagina into the posterior vaginal fornix, and gently withdraw your fingers, which is the method of external application of progesterone capsules. After inserting into the vagina, the progesterone capsule will be dissolved and absorbed under the action of secretion, and the purpose of treatment will be achieved. It is important to be careful not to get infected while using the medicine, so be sure to wash your hands or wear a finger cover while using the medicine. Keep your nails short to avoid damage to the mucosal tissue caused by long nails.
