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

In brief: 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.
