Bacterial vaginosis in pregnant women can be treated with suppositories such as clindamycin, nifurtimox, metronidazole and other suppositories given vaginally. Bacterial vaginosis during pregnancy is a relatively high incidence disease, which may cause the patient’s local flora imbalance, decreased resistance, and the growth of stray bacteria, leading to the patient’s vaginitis, followed by upward infection, premature rupture of membranes, intrauterine infections, fetal miscarriage, preterm labor, and so on. Bacterial vaginosis during pregnancy manifests itself in the form of foul-smelling secretions and increased secretions, and for such patients it is important to consult a doctor and do a secretion test in a timely manner. If the secretion test suggests bacterial vaginosis, give appropriate treatment. Pregnant women with bacterial vaginosis can use suppositories such as clindamycin, nifurtimox, metronidazole and other suppositories to be given vaginally under doctor’s supervision, but it is recommended that metronidazole be used for treatment after the third month of pregnancy. Vaginal medication is given for 7-10 days, and the medication is stopped for 3 days for review to determine whether the patient is cured.
