To treat bacterial vaginosis, your doctor may prescribe one of the following medications:
- Metronidazole (Flagyl, Metrogel-Vaginal, others). This medicine may be taken orally — as a pill that you swallow. Metronidazole is also available for use topically, as a gel that you insert into your vagina. To avoid the potential for stomach upset, abdominal pain or nausea while using this medication, avoid alcohol during treatment and for at least one day after completing treatment — check the instructions on the product.
- Clindamycin (Cleocin, Clindesse, others). This medicine is available as a cream that you insert into your vagina. One effect of using clindamycin cream is that it may weaken latex condoms during treatment and for at least three days after you stop using the cream.
- Tinidazole (Tindamax). This medication is taken orally. Tinidazole has the same potential for stomach upset and nausea as oral metronidazole does, so avoid alcohol during treatment and for at least one day after completing treatment.
Generally, it's not necessary to treat a woman's male sexual partner, but bacterial vaginosis can spread between female sexual partners. Female partners should seek testing and, if indicated, treatment of bacterial vaginosis. It's especially important for pregnant women with symptoms to be treated, as this may decrease the risk of premature delivery or low birth weight.
Take your medicine or use the cream or gel for as long as your doctor prescribes it — even if your symptoms go away. Stopping treatment early may increase the likelihood of recurrence.
Despite effective treatments for bacterial vaginosis, recurrence of symptoms within three to 12 months is common. Researchers are exploring treatment regimens for recurrent bacterial vaginosis. If your symptoms recur soon after treatment, talk with your doctor about treatment options, one of which is extended-use metronidazole therapy.
A self-help approach is lactobacillus colonization therapy — which attempts to boost the number of good bacteria in your vagina and re-establish a balanced vaginal environment — possibly accomplished by eating certain types of yogurt or other foods containing lactobacilli. However, research to determine the benefits and risks of probiotic therapy is lacking.
