Because all medications cannot be completely absorbed in a woman’s vagina, a drug residue will form after the effects of the treatment have passed. The inflammation of the patient is accompanied by an increase in vaginal discharge. It is normal for the drug residue mixed with the discharge to be expelled by gravity after the patient’s activity. In order to maximize the effect of the medication and minimize the irritation of the drug residue and leukorrhea, it is recommended that the patient use the medication at night before going to bed, as this will not cause the drug to be excreted soon after being placed. It is advisable to use a douche to flush out the residue of the last medication and excess leukorrhea from the vagina before administering the medication. This will increase the effectiveness of the medication and reduce the amount of drug residue and leukorrhea in the vagina, which will reduce the amount of discharge and prevent excessive discharge from irritating the vulva and causing itching and discomfort.
