How long should it take for Metronidazole to start working?

Hi everyone, I was diagnosed recently with BV and I have been prescriped a 14 day dose of 400mg Metronidazole. It’s my 6th day taking the medicine and I still have symptoms. I read online it should take 3-4 days for the 7 day course of Metronidazole to relieve symptoms, is it any different from the 14 days course or am I just being impatient? I’ve never had BV before so I’m not sure what to expect.
Thank you!

The amount of time that it takes an antibiotic to work really depends on a number of factors (the bacteria, the dose, lifestyle, your body's metabolism, etc.). My advice would be to wait a couple more days to see if there is an effect and if not, to either call your dr or make another appointment.

You probably already know this but PLEASE take the full 14 day dose. If not, it could lead to the bacteria becoming resistant and will make the infection that much harder to treat.

tldr; take the full course of antibiotics and inform your dr if there's still no change in a couple of days.

Good luck
