What is Metronidazole?

Metronidazole is a prescription medicine available to buy online, belonging to a class of antibiotics known as nitroimidazoles. As Metronidazole can be used to combat most bacteria, it has a wide range of uses including its primary use of treating bacterial infections, such as bacterial vaginosis and trichomonas vaginalis. Additionally, it can also be used to treat chronic skin conditions like acne rosacea. Metronidazole is a potent antibiotic and therefore is sometimes purchased as a single course of five 400mg tablets. If symptoms persist, however, a seven day course or longer of Metronidazole may be required.

Short facts about Metronidazole
How to take

1 tablet of Metronidazole is to be taken 3 times a day, either over the course of 2 days or 7 days.

How it works

Metronidazole is a powerful antibiotic that prevents bacterial cells from reproducing and spreading, leaving them vulnerable to your natural immune system.


Metronidazole is an extremely potent antibiotic, and usually just a single dose is required to kill bacterial infections.


Metronidazole is available to buy online as 400mg tablets, either as a single dose or as a 7 day treatment.

Side effects

The most commonly reported side effects of Metronidazole are dizziness, headache, nausea, stomach pain, changes in taste and dry mouth.

How does Metronidazole work?

Bacterial infections are caused when microscopic bacteria inhabit and reproduce inside a person's body. Metronidazole stops the bacteria from spreading by disrupting their cellular division, which prevents them reproducing and spreading. With the bacteria neutralised, your own natural immune system is able to destroy the infection completely.

How to take Metronidazole?

Metronidazole is to be taken in a 400mg dose, three times a day:

  • Take Metronidazole exactly as prescribed by one of our doctors.
  • Be sure to store Metronidazole at room temperature away from moisture and heat.
  • Metronidazole should never be taken more than three times in a 24 hour period.
  • This medication can be taken with or without food.


The dosage you need to take of Metronidazole will depend upon the extent of your infection. As Metronidazole is a very effective antibiotic, it is usually taken in a single treatment: five tablets of 400 mg, spread over the course of two days. However, if this proves inadequate, you can buy Metronidazole as a seven day course.

Side effects and precautions

Side effects are rarely reported when taking Metronidazole, however, there are some mild side effects associated with the drug. As the length of treatment is so brief, these are not usually found to be particularly troublesome. Common side effects can include dizziness, headache, diarrhoea, nausea, stomach pain, loss of appetite, constipation, changes in taste, and dry mouth.

Metronidazole is a safe drug with a low likelihood of side effects, although there are some precautions that you should consider before you buy this medication:

  • Metronidazole may be passed on through breast milk, so if you are currently nursing a baby, you should refrain from taking this medication.
  • You should not drink alcohol whilst on Metronidazole, and should continue to refrain from drinking for three days after finishing your course of treatment.
  • Talk to your doctor before taking Metronidazole, as it may interfere with your oestrogen contraceptive pill.

Furthermore, Metronidazole should not be taken if you are currently dealing with, or have a history of, any of these conditions:

  • Liver disease, or reduced liver function
  • Any stomach or intestinal disease, such as Crohn's disease
  • If you are allergic to Metronidazole
  • Epilepsy or nerve disorders
  • A bloodcell disorder, such as anemia

Note: Decisions about treatment are for both the prescriber and the person to jointly consider during the consultation. However, the final decision will always be the prescriber’s.
