Thank you so much for your question. I am so sorry that you have dealt with bacterial vaginosis for so long. As I am sure you know, it can be quite unpleasant!
Bacterial Vaginosis (BV) is the name of a condition in women where the normal balance of bacteria in the vagina is disrupted and replaced by an overgrowth of certain bacteria. It is sometimes accompanied by discharge, odor, pain, itching, or burning. It affects more than 1 million pregnant women in the US. Your doctor is right. The metronidazole cream is really a first try and, in my experience is often not effective enough. Metronidazole, also known as Flagyl, is a Category B medication (Category C medications should not be taken during pregnancy). As with most medications, it does cross the placental barrier and enter the fetal circulation. Reproduction studies have been performed in pregnant rats at doses up to five times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to metronidazole. There are, however, no adequate and well-controlled studies in pregnant women. Again, as with all medications, metronidazole should be used during pregnancy only if clearly needed.
Your situation is clearly an indication to switch from the vaginal cream to the oral pill. It is not good for either you or the baby to have untreated bacterial vaginosis. Please follow your doctor’s recommendation and take the medication exactly as prescribed. If you were to stop it too early your vaginosis may not fully clear up. I hope this helps and please let me know when you feel better!
