Medications
Antibiotics are the standard treatment for
bacterial vaginosis. Metronidazole (Flagyl) and
clindamycin (Dalacin) are the first-choice medications for treating bacterial
vaginosis. For women who cannot tolerate metronidazole, the broad-spectrum
antibiotic clindamycin is a good option.
These antibiotics can be given by mouth (orally) or inserted into
the vagina. During pregnancy, women who are high-risk for preterm labour are
advised to avoid vaginal application of any treatment. Some doctors recommend
that all pregnant women avoid vaginal treatments.
Studies generally indicate that vaginal antibiotics are as
effective as oral antibiotics for treating bacterial vaginosis.10 Medications inserted into the vagina cause fewer side effects
than oral medications, although they can make you vulnerable to
vaginal yeast infection.
When considering treatment for bacterial vaginosis, ask your health
professional whether you should:
- Use oral medication or medication inserted into
the vagina. Some women prefer taking pills to using a vaginal medication.
- Avoid having sex during treatment.
- Continue treatment
during your menstrual period. Medication placed in your vagina is more
difficult to use during your period, but your health professional may recommend
continuing treatment during this time.
- Avoid drinking alcohol
during treatment with metronidazole. This medicine can cause severe nausea and
vomiting if you drink alcohol when taking it. Clindamycin does not.
The mineral oil in clindamycin cream or ovules can cause latex
condoms or diaphragms to fail. This is also true for metronidazole cream and
tablets (the gel is fine for use with condoms and diaphragms). Don't trust barrier methods of birth control when using this type of
vaginal medication.
