Is it normal to experience bleeding and discharge of foreign substances after using a feminine antibacterial gel?
Generally, it is normal to have a small amount of blood and foreign substances resembling drug residue after using a feminine antibacterial gel, as long as there is no discomfort. However, if there is heavy bleeding or abnormal discharge accompanied by odor or pain, this is considered abnormal. If in doubt, it is recommended to seek medical advice promptly. Detailed analysis is as follows:

If the blood appears only as light spotting that stops quickly, and the discharge consists of unabsorbed gel residue mixed with vaginal secretions, without symptoms such as itching or burning, this is usually normal. After the gel exerts its effect inside the vagina, unabsorbed components are naturally expelled along with vaginal discharge. Minor irritation to the mucosa during application may also cause slight bleeding, which does not affect treatment—continue using the medication as prescribed.
If the bleeding is heavy (similar to menstrual flow) and persistent, the discharge is pus-like or has a foul or fishy odor, and is accompanied by vaginal pain, lower abdominal pressure, or other discomforts, this is abnormal. It could indicate mucosal damage caused by the gel's irritation, or underlying conditions such as cervical lesions or worsening vaginal inflammation. In such cases, discontinue use immediately to prevent further deterioration of symptoms.
After using feminine antibacterial gel, monitor the amount and nature of discharge as well as your body’s response. Maintain external genital hygiene and change underwear frequently. If any abnormalities occur, seek prompt medical evaluation through a gynecological examination to determine the cause and adjust treatment accordingly or receive targeted therapy.
