Frequently Asked Questions

  • How many Metronidazole tablets do I need to take to treat Bacterial Vaginosis?

    Take 1 tablet twice a day for 7 days and ensure you complete the course. You will need 14 Metronidazole 400mg tablets in total for a full course of treatment.

  • Do I take the Metroniadazole tablets with or after food?

    Metroniadazole tablets can be taken with or without food. Some people feel sick or may be sick (vomit) when they take Metronidazole. If this happens, you should try to take the tablets with or after food. A metallic taste is a common side-effect when taking Metronidazole.

  • Can I take Metroniadazole and drink alcohol?

    Do not drink any alcohol while taking Metronidazole.This is a well documented interaction that can cause vomiting, flushing or an increased heart rate. This advice also applies to items that contain alcohol, like mouthwash. Allow 2 days for any trace of the antibiotic to clear out of your system before consuming any alcohol or alcohol containing products.

  • My symptoms have got better but haven't cleared completely. What do I do now?

    Some women may require an additional course of Metronidazole should the initial course be unsuccessful. This is quite normal. If you need another course of treatment, it is importnat to check if the inital course was taken correctly as this will influence the choice of the second course of treatment.

  • Will BV antibiotics interfere with my contraceptive pill?

    It was previously recommended that if you were taking antibiotics, that you use another form of contraception whilst taking the course and for 7 days after finishing. This advice has now been changed. Metronidazole, used to treat Bacterial Vaginosis, does not affect the contraceptive pill and no additional or precautionary contraceptive methods are necessary whilst treating BV.

  • Can I have sex whilst I am receiving treatment for BV?

    It is best to avoid sex until you have finished your course of treatment and your infection has completely cleared up. This is to avoid upsetting the pH balance in the vagina and worsening symptoms during treatment.

  • What should I do if I forget to take a Metronidazole tablet?

    Take the missed dose as soon as you remember unless it is nearly time for your next tablet.  Do not take two tablets to make up the missed dose.
