If metronidazole 500 2x a day for BV doesn't work, would increasing the dose work?

If metronidazole 500 2x a day for BV doesn't work, would increasing the dose work?

Unlikely.: Metronidazole usually works well for routine bacterial vaginosis at that dose for 7 days. If you are not responding after a few days of treatment, you may need to be evaluated for another cause of your symptoms. If you initially get better and then your symptoms return, it could be due to reinfection from your partner. Condom use will help prevent this or consider having your partner treated. ...Read more

Would 2 single 2g doses of metronidazole 2days apart cure BV if the week long course didn't work?

Would 2 single 2g doses of metronidazole 2days apart cure BV if the week long course didn't work?

Possible: The usual treatment for BV is metronidazole 500 mg twice daily for seven days - but a single 2 gram dose can also be effective. The cure rate would be a bit better by repeating the 2 gram dose.

If the seven day treatment did not work at all - it may not be BV. ...Read more

If I take a single 2g dose of metronidazole for BV and it does not work will the bacteria become resistant? Should I try the week long course after?

If I take a single 2g dose of metronidazole for BV and it does not work will the bacteria become resistant? Should I try the week long course after?

Not likely: Gardnerella, the bacterium that causes BV shows very low levels of resistance to Flagyl. If the 2g dose was ineffective, the week long course could work better. Also, I don't know your situation, but being tested for STD's could also be appropriate, since many will cause the same symptoms. If your symptoms don't resolve, see your doctor. Hope this helps! ...Read more

Is it safe to take 2 2g doses of metronidazole for BV in a 2 day period?

Is it safe to take 2 2g doses of metronidazole for BV in a 2 day period?

Metronidazole dosing: Luckily metronidazole is a relatively safe antibiotic. It doesn't quite make sense to me why you would be taking the large dose consecutively? Usually the 2 gram dose is a 'one time' thing to get rid of BV -bacterial vaginosis. After 1 or 2 days, that dose will have cleared out of the system. Not sure 'why' your doc would give u another round? Maybe you went to a different clinic? It should be OK. ...Read more
