Hello dear Understand your concern Yes metronidazole should be used for bacterial vaginosis. But first you have to confirm the diagnosis by vaginal swab test. You can also contact local lady doctor to confirm the diagnosis. If bacterial vaginosis will be confirmed then take following advice and drugs: Tablet metronidazole for 7 days. Lactobacillus vaginally or orally, avoid excessive sweets. Use V-Vaginal plus wash to maintain pelvic hygiene. Take war water shower frequently. Wipe pelvic area before and after sex and urination. Wear pure cotton loose inner wear. Avoid sex till you get better. So you can contact local doctor for prescription and it have very minor cost. Hope this may help you Best regards Dr. Sagar
