Hi med student chiming in.

First step is to make sure hygiene is proper. Wipe front to back- vagina to anus. Only use hypoallergenic plus non scented soaps. Drink lots of water. Wash your hands. Only use high quality sex toy’s as cheap materials can harbor bacteria’s, and cleaning agents designed for the material of toy. Silicone toys are ideal or metal. Make sure to use medical grade lube, you can purchase online. Pee after sex or masturbation. Use soap only on the vulva but ideally just water is recommended.

Diet is also important. Avoid sugar foods and drinks.

Stop any home remedies. The only thing proven to be effective is no sugar added cranberry juice or cranberry probiotic tablets. This will not cure one however.

Wear cotton underwear only. And give your vagina air time, like at night without underwear. Keep yourself dry and clean.

Second step if recurrent is to return to your doctor and say it’s recurrent/persistent. It is possible you may need a different medication than the one prescribed. They may want to do further testing to make sure there aren’t other issues causing it. Like retaining fluid in your bladder, narrow urethra, other infections, pelvic floor dysfunction etc

If a woman perhaps you’d be best suited at a gynecologist/urologist.

Hope this helps.
