Although BV will sometimes clear up without treatment, all women with symptoms of BV should be treated to avoid such complications as PID. Male partners generally do not need to be treated. However, BV may spread between female sex partners.

Treatment is especially important for pregnant women. All pregnant women who have ever had a premature delivery or low birth weight baby should be considered for a BV examination, regardless of symptoms, and should be treated if they have BV. All pregnant women who have symptoms of BV should be checked and treated.

Some physicians recommend that all women undergoing a hysterectomy or abortion be treated for BV prior to the procedure, regardless of symptoms, to reduce their risk of developing PID.

BV is treatable with antibiotics prescribed by a health care provider. Two different antibiotics are recommended as treatment for BV: metronidazole or clindamycin. Either can be used with non-pregnant or pregnant women, but the recommended dosages differ. Women with BV who are HIV-positive should receive the same treatment as those who are HIV-negative.

BV can recur after treatment.

BV is not completely understood by scientists, and the best ways to prevent it are unknown. However, it is known that BV is associated with having a new sex partner or having multiple sex partners. It is seldom found in women who have never had intercourse.

The following basic prevention steps can help reduce the risk of upsetting the natural balance of bacteria in the vagina and developing BV:

• Be abstinent.

• Limit the number of sex partners.

• Do not douche.

• Use all of the medicine prescribed for treatment of BV, even if the signs and symptoms go away.
