Although the CDC does not take a definitive stance on treating trichomoniasis during pregnancy, it recommends a single 2-g dose of metronidazole if treatment is deemed necessary. One study has found an association between the use of metronidazole during pregnancy and premature delivery, but this result has not been reproduced by other studies. [112] Treatment of trichomoniasis during pregnancy may relieve symptoms of vaginal discharge or prevent the rare complication of neonatal respiratory infection with trichomoniasis. [11] Vertical transmission of trichomoniasis during delivery is relatively rare, but respiratory or genital infection of the newborn during delivery has been reported. [48]

Infected asymptomatic pregnant women may wish to defer treatment to after 37 weeks’ gestation. [48, 11]
