Metronidazole FAQs

What is Metronidazole?

Metronidazole is an antibiotic used to treat a number of bacterial infections, namely bacterial vaginosis (BV). When taken twice daily for 7 days, it kills bacteria cells and negates symptoms of the common bacterial infection.

How does Metronidazole work?

Metronidazole works to treat BV by damaging the DNA of the bacteria that causes bacterial vaginosis. This stops the growth of bacteria in the vagina, easing symptoms and treating your infection at the source.

Metronidazole mainly targets harmful bacteria, but it can affect levels of good bacteria too. However, once you stop taking Metronidazole tablets, your body will quickly restore the balance of healthy bacteria, leaving you feeling good and free of infection.

What are the benefits of Metronidazole?

There are many benefits of using Metronidazole gel to treat BV:

Treats infections at the source

Metronidazole targets bacteria DNA directly, meaning it doesn't just reduce symptoms, it treats the root cause of your infection.

Convenient

Metronidazole tablets are taken twice daily in the morning and evening, making it easy to fit into your schedule.

Short treatment course

Metronidazole tablets are usually only prescribed for a 7-day course, helping you get better as fast as possible.

How effective is Metronidazole?

Metronidazole is a highly effective treatment for bacterial vaginosis, completely clearing the infection within 7 days.

One clinical study found that 76% of women taking Metronidazole 500 mg tablets were completely cured, compared to just 5% of women taking a placebo.

How long does Metronidazole take to work?

You should notice the effects of Metronidazole within a few days of taking your first tablet. During this time, symptoms should reduce and you should start feeling better. Complete resolution of symptoms is usually felt after 7 days of consistent use. If your infection worsens or symptoms don't resolve, seek medical attention.

How to use

How and when should I take Metronidazole?

Take one 500 mg tablet twice per day for 7 days. Leave at least 12 hours inbetween doses to ensure a steady supply of medicine. You can take your tablets with or without food, but taking them with meals can prevent an upset stomach.

Swallow each tablet whole with a glass of water. Do not cut, crush, or chew your tablets.

What if I miss a dose?

If you forget to take a tablet, take it as soon as you remember, and take your next one at the usual time. If it is almost time for your next dose, skip the missed tablet and take your next one at the usual time. Do not take a double dose to make up for a missed one.

How long should I use it for?

Metronidazole tablets should be taken for a course of 7 days to completely clear your infection.

It is important to complete the entire course prescribed, even if your symptoms resolve before you finish. If you do not complete the full course, you risk your infection returning even stronger than before.
