Metronidazole 400mg tablets are a type of antibiotic. Metronidazole (also spelled Metronidazol) can be used to treat a number of different infections however, they can be supplied online by The Independent Pharmacy to treat Bacterial Vaginosis (BV) in women. They are an effective treatment, taken for one week, that normally helps to clear symptoms in two to three days.

Metronidazole is suitable to buy online if you have previously suffered from Bacterial Vaginosis before that has been diagnosed and successfully treated by your GP.

If you have had it
Diagnosed by your doctor before
Been prescribed metronidazole and it has treated the infection successfully
You symptoms include fishy odour and but not always a thin discharge

You would qualify for treatment online. You are also suitable for treatment if you have had a positive test for Bacterial Vaginosis and now require treatment. If you have not suffered from BV before, your symptoms are different or you have had a negative test result, you should see your GP for further investigation.

Bacterial Vaginosis is not a sexually-transmitted disease and normally presents as white, grey or yellow vaginal discharge that is thin and watery – not to be confused with Thrush. It may have a 'fishy' smell that is particularly strong after sex. To find out more about Bacterial Vaginosis, see our Bacterial Vaginosis page. It does not usually cause a rash or lesions – if you experience these symptoms, this could be a sign of genital herpes, while small bumps are more likely to be genital warts. To be sure, you should consult a doctor or you can contact us for free impartial advice.

Metronidazole may alter the effectiveness of your contraceptive pill. Additional precautionary measures may be necessary whilst you are taking Metronidazole.

*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

Take ONE tablet TWICE daily for SEVEN days. Metronidazole should be taken with or after food.

Always ensure that you complete the course, even if you think your symptoms have improved. This will help to prevent the infection coming back.

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 Metronidazole tablets with or after food?

    Metronidazole 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 Metronidazole 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 important to check if the initial 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.

  • Will Metronidazole affect my period?

    Since Metronidazole is only taken for a short amount of time, it should not have lasting or ongoing effects on your period.

    Antibiotics can affect a woman’s period, as one of the effects can be a reduced amount of oestrogen – the hormone responsible for your menstrual cycle. This is because antibiotics are metabolized by the liver, which is also responsible for metabolizing oestrogen and progesterone. Some women may experience a period delay, or your ovulation may occur later than normal.

  • What happens if Bacterial Vaginosis goes untreated?

    While unpleasant, BV does not usually cause other health problems to occur. But if it is left untreated, you may be vulnerable to an increased risk of STIs, such as herpes, chlamydia and gonorrhea. Untreated BV can also lead to pelvic inflammatory disease, where the uterus or fallopian tubes become infected. For this reason, it’s best to treat the symptoms as soon as they’re diagnosed.
