There is no need for medication to prevent vaginal infections after swimming; other effective methods of prevention should be used.
Don’t swim in unclean pools, especially those with contaminated water. Don’t swim for too long, the water pressure tends to cause muscle contraction, which can easily cause body fatigue and bacteria will have a chance to enter the vagina.
Try not to touch public objects after swimming, don’t sit anywhere, it is better to lay a bath towel when you sit down. After swimming, you should wash your whole body in time and use a shower to rinse off any disease-causing microorganisms that may have contaminated your skin and vulva.

If vaginal inflammation occurs after swimming, it is recommended to consult a doctor in a timely manner, complete the relevant examinations, under the guidance of the doctor to clarify the cause of the disease, targeted treatment, to avoid delaying the condition.
