How to take metronidazole

To treat trichomoniasis, you should take 1 metronidazole twice a day for 7 days. Every time you need to take metronidazole you should:

  1. have some food before you take your metronidazole tablet.
  2. swallow your metronidazole tablet whole with a glass of water.
  3. avoid drinking any alcohol before, during or after you take your metronidazole tablet.

You should complete your 7 day metronidazole treatment course, even if you feel better after a few days. If you do not complete your course, the trichomoniasis infection can come back and you may become unwell.

After you complete your 7 day metronidazole treatment course, you have to wait 2 more days before you can start to drink alcohol again.

If you forget to take your metronidazole tablet:

  • take your metronidazole tablet as soon as you remember
  • do not take 2 tablets of metronidazole to make up for a tablet you forgot

You can find more details about how to take metronidazole in the patient information leaflet.
