The vaginal discharge after using vaginal gel is composed of drug residue, vaginal epithelial cells and cervical necrotic tissue mixed in the vaginal discharge. If it is not too much, it does not need special treatment and is a normal physiological phenomenon. It is recommended to do a good job of local cleanliness and hygiene, wash with warm water frequently to keep the pubic area clean and dry. At the same time, it is necessary to wear loose, cotton underwear to maintain good ventilation, and try not to wear chemical fiber underwear to avoid long-term local stimulation of the vagina by moisture, which can breed bacteria and aggravate the disease. If the discharge has a foul smell or bleeding symptoms, you should go to the gynecology department as soon as possible and cooperate with the doctor for gynecological and leucorrhoea tests to confirm whether there is any infection or ulcers and to treat the symptoms after diagnosis.
