How to treat reoccurring and prolonged bv? tried many rounds of flagystatin ovules, no cure. and two weeks of metronidazole didnt worked. been having bv for a year?

You can try one of these approaches or a combination: suppression Tx with metronidazole gel 7.5%, 5-gram dose, twice a week for 4-6 months or boric acid vaginal suppository every night x 1 month or/and sex abstinence vs partner with condom use . Suppression therapy or boric acid suppository should be started after 1 week of induction therapy with standard dose of oral metronidazole or tinidazole.
