What is Metronidazole?

Metronidazole is an antibiotic which is used to treat a number of bacterial infections including bacterial vaginosis. This treatment is available in the forms of oral tablets or a topical vaginal gel.

The antibiotic, Metronidazole, is also the active ingredient of some rosacea treatments such as Rozex and Metrogel.

When taking any course of antibiotics, it is important to complete the course of treatment completely, even if you feel better or the infection has cleared. Ceasing antibiotic treatments too early can cause your infection to return.

The amount of metronidazole you take and how long you take it for depend on the severity of your infection and the administrative route of the medicine. Always follow the doctors instructions when taking antibiotics.

What is Bacterial Vaginosis?

Bacterial Vaginosis (BV) is a vaginal infection which affects 1 in 3 women in the UK. While it is not classed as an STI, the infection can be triggered by sexual intercourse and even passed on from one woman to another during sex.

What causes bacterial vaginosis?

There are a number of potential causes of BV, including:

  • using perfumed products in and around the vagina
  • changing sexual partners
  • change in vaginal pH brought on by periods
  • using strong detergents when washing underwear
  • using a form of contraception known as a UID

Is bacterial vaginosis the same as thrush?

BV is often mistaken for thrush due to the similarities in the symptoms the two infections cause. The difference between the two conditions lies in the consistency and odour of vaginal discharge. While thrush often produce a thick, odourless discharge which looks similar to cottage cheese, the discharge associated with bacterial vaginosis is often thin, watery and foul or fishy smelling.

If you notice a change in your vaginal discharge, speak to your doctor or pharmacist for advice.

How does Metronidazole work?

Metronidazole is an antibiotic which kills bacteria by interfering and altering the DNA of the bacteria.

The change inhibits the cells' ability to reproduce, stopping the infection from spreading. This gives the immune system a better chance of fighting the infection.

Metronidazole is only effective against bacteria which do not require oxygen to survive, also referred to as anaerobic bacteria.

How do I take Metronidazole?

Metronidazole is available in three formulations: capsules, tablets and vaginal gel. The form of the treatment depends on the severity of the infection.

For the treatment of a bacterial infection, such as bacterial vaginosis, adults should start with an 800 mg dose. After 8 hours have elapsed, 400 mg should be taken every 8 hours.


Swallow each capsule whole with a glass of water. Metronidazole capsules can be taken with or without food.


Swallow each tablet whole with a glass of water. Take Metronidazole tablets without food.

Vaginal gel

Vaginal gel is applied internally into the vagina using the provided applicator.

Fill the applicator to the indicated line with the gel. Insert the applicator into the vagina While gently removing the applicator, dispense the Metronidazole gel into your vagina.

Depending on the severity of your condition, the doctor will determine the most appropriate course of treatment for you.

If you are not sure how to take the medicine prescribed to you, read the enclosed patient information leaflet or speak to your doctor or pharmacist.

It is vital to complete the course of antibiotics you have been prescribed to prevent the infection from coming back.
