During pregnancy, women are usually prescribed oral medicine.
When considering treatment for bacterial vaginosis, ask your doctor whether you should:
Use oral medicine or medicine inserted into the vagina. Some women prefer to take pills rather than using a vaginal medicine.
Avoid having sex during the time that you are being treated.
Continue treatment during your menstrual period. Medicine placed in your vagina is harder to use during your period, but your doctor may recommend continuing treatment during this time.
Avoid drinking alcohol during treatment with metronidazole or tinidazole. These medicines can cause severe nausea and vomiting if you drink alcohol when you are taking one of them. Clindamycin does not.
The oil in clindamycin cream and ovules can weaken latex. This means condoms and diaphragms may break, and you may not be protected from STIs or pregnancy.
