Testing and Treatment

Can bacterial vaginosis be cured?

BV will sometimes go away without treatment. But if you have symptoms of BV, you should be checked and treated. You must take all of the medicine prescribed to you, even if your symptoms go away. A health care provider can treat BV with antibiotics, but BV may recur even after treatment. Treatment may also reduce the risk for some STDs.

Male sex partners of women diagnosed with BV generally do not need to be treated. BV may be transferred between female sex partners.
