What is Metronidazole?

It is an antibiotic used to treat bacterial infections of the vagina, stomach, liver, skin, joints, brain, and respiratory tract. It is important to note that Metronidazole will not treat a vaginal yeast infection. It will not treat a viral infection such as the common cold or flu.

How It's Used

Metronidazole, which is marketed under the brand name Flagyl, is an antibiotic and antiprotozoal medication. It is used either alone or with other antibiotics to treat pelvic inflammatory disease, endocarditis, and bacterial vaginosis. Metronidazole is used to treat infections caused by a wide variety of bacteria known collectively as anaerobic bacteria. These bacteria don't need oxygen to grow and multiply and can cause infections in areas of the body such as the bones, gut, pelvic cavity and gums.

Metronidazole is commonly prescribed to treat an infection called bacterial vaginosis. It is also prescribed before gynaecological surgery and surgery on the intestines to prevent infection from developing. It can safely be taken by people who are allergic to penicillin. Metronidazole is also used, alongside other medicines, to get rid of Helicobacter pylori, a bacterial infection often associated with stomach ulcers.


Metronidazole, also known as the branded version Flagyl, is an antibiotic used in the treatment of infections such as bacterial vaginosis (BV). The medication comes in the tablet form in either 200mg, 400mg or 500mg. You can find the 400mg tablets here at UK Meds.

What to do before taking Metronidazole

As with all medications, this medication is not suitable for everyone and it is important to consult your doctor before proceeding. Ensure your doctor is aware if any of the following applies to you:

  • If you have previously encountered an allergic reaction to a different medicine.
  • If you have any problems with your liver.
  • If you are taking any other medicine, including medicines you have obtained without a prescription, herbal and commentary medicines.
  • If you feel you will have an urge to drink alcohol during treatment.
  • If you have an inherited blood disorder named porphyria.

How To Take

  • Before starting any treatment, you should read the patient information leaflet included by the manufacturer of the medication from inside the packaging. The leaflet will provide you with all the information you need to know regarding taking the tablets and any side-effects you may experience taking this treatment.
  • Do not crush or chew the tablets, take your dose during or after a meal with a glass of water.
  • Always take exactly as your doctor has told you to.
  • The typical dosage for bacterial vaginosis is 400mg twice daily for 7 days.
  • If you forget to take your dose, you should take it as soon as you remember to. Do not double dose to make up for a forgotten dose.
  • If you have taken too many tablets, contact your nearest emergency department or doctor immediately.

Side effects and precautions

It is important that you do not drink alcohol for the duration of the treatment and for 48 hours after finishing your course of metronidazole. Drinking alcohol whilst taking this medication will most likely cause very unpleasant side effects including feeling sick and other effects such as a ‘thumping heart’, headache and hot flushes.

Do not take this medicine if you are allergic to it, nitroimdazoles, povidone, magnesium stearate, colloidal anhydrous silica or maize starch. If you experience a rash, difficulties breathing/swallowing, swelling of the face, lips, tongue or throat, stop taking immediately as these are signs of an allergic reaction.

Your urine may appear darker whilst you are taking Flagyl. This is expected and should not alarm you.

Always consult your doctor before taking this treatment with other medicines including cough and cold remedies, as these may contain alcohol.
