What is Metronidazole?

Metronidazole is an antibiotic that is used to treat a number of bacterial infections, including bacterial vaginosis (also known as gardnerella vaginalis) and trichomonas vaginalis.

By combating the harmful bacteria that is causing the symptoms, Metronidazole is available in a course of tablets (that should be fully completed) and works quickly by reducing the uncomfortable symptoms allowing your body to combat the infection.

At HealthExpress, we supply Metronidazole 400mg tablets in 21 tablet pill packs.

How does Metronidazole work?

Metronidazole affects the bacteria's ability to spread, which will help reduce any discomfort the symptoms are causing within days of starting the treatment. By killing off bacteria by entering each individual protozoa cell and interfering with the cell DNA, this action prevents the bacteria from duplicating so that it can't spread and begins to die. This will help your body to cope better with the bacteria and complement the antibiotic actions to completely remove it from your system.

If taken exactly as prescribed, this treatment can completely cure the infection.

What are the benefits of Metronidazole?

One course of Metronidazole can completely cure bacterial vaginosis and trichomonas vaginalis. The sooner these conditions are treated, the less effect they will have on your overall health. The vast majority of people respond very well to Metronidazole and only a short course is needed to clear the infection.

How to use Metronidazole 400mg tablets

The dosage you take of this antibiotic will depend on the condition. Metronidazole is a versatile medicine that can be taken in a low dosage over a 7-day period (take 1x 400mg tablet 3 times a day). At the moment we do not provide the vaginal gel alternative. If you find that you do develop side effects easily when taking medications or antibiotics, taking lower dosages over a longer period might be more suitable.

You should preferably take Metronidazole after or during meals and it is not advised that you consume any alcohol for the entire duration of your course, and for at least 48 hours afterwards as drinking whilst using Metronidazole can induce unwanted side effects. To make sure that you are completely free of the infection, you are recommended to do another STI test 2 weeks after completing your treatment.

What if I miss a dose?

Just take your missed pill as soon as you remember and continue the treatment as normal.

If it is almost time to take your next tablet, miss it out completely and never take two tablets to make up for it. If you have, keep a watchful eye on your health and seek further medical attention if you are feeling unwell.

What dosages are available for Metronidazole?

At HealthExpress, we offer Metronidazole in a 400mg tablet dosage, there is also a vaginal gel (0.75%) but this is not available here. This is ideal dose that is recommended by doctors that has been proven to be well-tolerated. However it is available in 200mg if you happen to be prone to side effects, and an 800mg that is only suggested if the level of your condition is particularly severe.

What are the side effects of Metronidazole?

Whilst even the side effects classed as "common" still only affect 10% of users, it is still essential that you familiarise yourself and take precautions if you are particularly sensitive to any of the ingredients.

Some of the most common side effects are:

  • Diarrhoea and constipation
  • Nausea, vomiting or abdominal pain
  • Unpleasant taste in the mouth, loss of appetite, itchy rash
  • Drowsiness, dizziness or headache.

Fortunately, these are not common and if they do occur, should lessen as the body becomes used to the treatment. If you do find any symptoms becoming worse, please ensure you speak to your doctor as soon as possible.

Interactions/precautions when using Metronidazole

Women over the age of 18 can buy Metronidazole online to treat bacterial vaginosis and both men and women can order the treatment to treat trichomonas, however certain groups should exercise caution. You may not be suitable to use Metronidazole (Flagyl) if you have:

  • blood cell disorders such as anaemia or leucopoenia,
  • epilepsy or nerve disorders.
  • an allergic reaction to its active ingredients

Metronidazole can sometimes affect or be affected by other medications; however there have been no known interactions when it comes to taking paracetamol.
