Bacterial vaginosis
- Bacterial vaginosis (BV) may increase risk of late miscarriage, preterm birth, premature rupture of membranes and post partum endometritis.
- There is no evidence to support screening asymptomatic women, including asymptomatic pregnant women, for BV.
- Symptomatic pregnant women should be treated in the usual way apart from avoiding high doses regimens of metronidazole (metronidazole 400mg oral twice daily 5-7 days). No teratogenic or mutagenic effects in infants have been found with metronidazole.
- Women with asymptomatic BV in pregnancy should be discussed with the woman's obstetrician as the evidence regarding the treatment of BV to prevent adverse outcomes in pregnancy is conflicting.
