What is Flagyl?

Flagyl is a treatment for bacterial vaginosis with the active ingredient metronidazole. It’s an antibiotic, so it’s also an effective treatment against many different bacterial infections that target other areas of your body.

Flagyl destroys the ‘bad’ bacteria causing the infection so allows your own immune system to fight back. For bacterial vaginosis, you’ll usually take it as a tablet.

How does Flagyl work?

The metronidazole in Flagyl works by killing off the cells causing the infection. When you have bacterial vaginosis, there’s an overgrowth of ‘bad’ organisms that change the pH of your vagina and cause the strange smells and discharge.

Flagyl enters these bad organisms and breaks down their DNA, destroying them. This limits the bacterial infection and stops it from spreading. Your immune system can then kill off any remaining infection.

What doses of Flagyl are there?

For bacterial vaginosis, Flagyl comes as 400mg tablets. The dose you take will depend on the stage of your infection and your own needs. But often the first dose is two tablets, so 800mg. After that, you’ll take one 400mg dose every eight hours.

Only take the amount you’re advised to. If you’re using our service, our clinicians will advise you on your dose. You can always send us a message if you have any questions.

How to take Flagyl

You should always take Flagyl as our clinician tells you.

  • Swallow the tablets whole, don’t crush or chew.
  • Take them with water, so they’re easier to swallow.
  • Take the tablets with food, or just afterwards. Flagyl will still work if you take it with food, but it will be more likely to upset your stomach.
  • Like every antibiotic, it’s important to finish the whole course of Flagyl. You should do this even if you’re feeling better.

How long does it take Flagyl to work?

Flagyl starts working almost immediately, reaching peak concentration in your blood between 20 minutes and three hours. But it will take time to completely get rid of your bacterial vaginosis. Our clinician will tell you exactly how long you need to take Flagyl for.

Usually, treatment of bacterial vaginosis with Flagyl takes five to seven days. Remember that you need to finish the course even if your symptoms seem to have cleared up. You shouldn’t stop taking Flagyl early, even if you think you’re fine.

What should I do if I make a mistake when taking Flagyl?

If you forget to take Flagyl, take your dose as soon as you remember. If it’s almost time for your next dose, just skip it instead. Don’t take a double dose to make up for missing a dose. You can always set an alarm to remember when you need to eat and take your Flagyl.

If you take too much Flagyl, seek medical attention right away. It helps if you can bring the packaging with you so you can show the clinicians what you’ve taken. If you have any questions about taking Flagyl, you can log into your account and send us a message. Our clinicians will get right back to you.

How we source info.

When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.

FAQ: Flagyl

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How is Flagyl different from other treatments for bacterial vaginosis?

Answer:
Unlike some treatments for bacterial vaginosis, Flagyl comes as tablets. Dalacin is a cream you apply to your vagina. Zidoval contains the same active ingredient as Flagyl, metronidazole, but it comes as a gel you put on topically. If you find it easier to take tablets than apply the treatment to your vagina, Flagyl could be the right choice for you.

Is Flagyl similar to any other treatments?

Answer:
Flagyl is a brand name, so you can buy similar tablets containing the same active ingredient, metronidazole. You can also buy a generic version, just called Metronidazole. They’ll all work in a similar way, but they might come in different dosages, look different or be called something else.

Flagyl also comes as a suppository. This kind of treatment isn’t usually used for bacterial vaginosis. It might be the right choice for you if you have a different kind of infection, or you’re unable to take tablets.

Can I have sex on Flagyl?

Answer:
You shouldn’t have sex while you’re taking Flagyl. This is true even if you’re using a barrier method of contraception like a condom. Sex will introduce new bacteria into your vagina and make your bacterial vaginosis harder to treat.

Even oral and anal sex can reduce the effectiveness of Flagyl. If you have a same sex partner, you might also spread bacterial vaginosis to them if you have sex before your treatment is finished. You can have sex safely seven days after your treatment is finished.

Can I take Flagyl if I’m pregnant?

Answer:
It’s usually not advised to take Flagyl during pregnancy. If you’re breastfeeding, small amounts of the drug may also pass to your baby from your system.

Always tell your clinician if you’re pregnant, might become pregnant or you’re breastfeeding before you take Flagyl. They can let you know the best treatment for you. If you’re using our service and you need advice, our clinicians can help you.

Can I drink alcohol on Flagyl?

Answer:
It’s not safe to drink alcohol and take Flagyl at the same time. This is because Flagyl interacts with alcohol and causes side effects. You might become very dizzy and nauseous when drinking on Flagyl. And if you’re sick, the medication might not be as effective.

Even once you’ve finished your course of Flagyl, you should wait for 48 hours before drinking alcohol. This allows all the medication to leave your system, so it won’t cause any problems if you drink.

Which foods should I avoid on Flagyl?

Answer:
There are no foods you have to avoid while taking Flagyl. A few people taking the medication may experience nausea. You can help with this by eating smaller meals of bland foods. You might want to avoid spicy or heavy foods if you’re feeling sick.

How effective is Flagyl?

Answer:
Flagyl is very effective for treating bacterial vaginosis. When taken as tablets, it has been shown to work 87–92% of the time. There are other self-care methods that can help you treat bacterial vaginosis, or stop it from coming back. You should avoid using scented soaps near your vagina. If you smoke, quitting smoking puts you at a lower risk of bacterial vaginosis.

Do I need a prescription for Flagyl?

Answer:
Flagyl is only available on prescription. Your clinician will need to make sure it’s suitable for you before they can prescribe it. If you have bacterial vaginosis, you just need to talk to our clinicians about your health. We’ll talk you through your options.

Why should I buy Flagyl online with Treated?

Answer:
Treated makes tackling bacterial vaginosis simple. You can do it all from home. Just talk to us about your health, and we’ll suggest suitable and safe treatments for you to pick from. Once you order, you’ll receive fast delivery right to you.
