What is Metronidazole?

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

By combating the production of the harmful bacteria that is causing the symptoms, Metronidazole works quickly helping to remove the infection with 2 to 3 days of use.

How does Metronidazole work?

Metronidazole affects the bacteria's ability to spread, which firstly helps to reduce any discomfort the symptoms may be causing within a few days. The treatment permeates individual protozoa cells interfering with the cell DNA, this action prevents the bacteria from duplicating so that it cannot spread and begins to die. This will help your body's defences to cope better with the bacteria and complement the antibiotic actions to completely remove it from your system.

What are the benefits of Metronidazole?

One course of Metronidazole 400mg can completely cure vaginal infections such as bacterial vaginosis (BV) and trichomonas vaginalis. The sooner these conditions are treated, the less effect they will have on your overall health. The vast majority of women respond very well to Metronidazole and only a short course is needed to clear the infection. It can also provide secondary benefits such as being an effective secondary treatment for:

  • helicobacter pylori infection (also known as H. pylori) which causes stomach ulcers
  • gum infections
  • parasitic diseases such as amoebiasis

How to use Metronidazole 400mg tablets

The dose and how often you take Metronidazole will depend on severity of the infection and what caused it. It is always important that you finish a course of antibiotics even if the infection appears to have cleared or you start to feel better. When taking this medication to treat bacterial vaginosis (BV):

  • Take one 400mg tablet should be taken twice a day over a 7 day period
  • You should preferably take the tablet during or after a meal
  • It should be swallowed whole with water, not chewed or broken

It is also not advised to 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 rid of the infection, you are recommended to have a health check-up or take a test 2 weeks after completing your treatment.

At HealthExpress, we offer Metronidazole in a 400mg tablet dosage which is ideal dose that is recommended by doctors that has been proven to be well-tolerated.

What if I miss a dose?

Just take your missed tablet 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 are the side effects of Metronidazole?

Although side effects are not too common, they can occur when taking prescription medicine such as Metronidazole. 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
  • Constipation
  • Nausea
  • Vomiting or abdominal pain
  • Unpleasant taste in the mouth
  • Loss of appetite

Rare side effects include:

  • Drowsiness
  • Headache.
  • Double vision
  • Joint pain
  • Jaundice
  • Skin rash or skin problems

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 severe or worsen, please ensure you speak to your doctor as soon as possible. You can also read the attached patient information leaflet for a full list of associate side effects.

Interactions/precautions when using Metronidazole

Women over the age of 18 can buy Metronidazole 400mg tablets 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 this if you:

  • have liver disease
  • have a stomach or intestinal disease
  • have blood cell disorders such as anaemia or leucopoenia,
  • have epilepsy or nerve disorders.
  • have an allergic reaction to Metronidazole tablets or its active ingredients

Although there have been no conclusive studies to show that Metronidazole is not suitable for use during pregnancy, it is also not possible to say what effects it may have on the unborn foetus. It is essential to consider the benefits and risks before deciding to use this treatment whilst pregnant or when breastfeeding.

It is recommended that those with Crohn's disease should avoid the use of Metronidazole as certain studies have shown a possible increase in the likelihood of colon of breast cancer. However, the likelihood of gastrointestinal cancers is only increased in the long term use of Metronidazole.

Metronidazole tablets can sometimes affect or be affected by other medications; however there have been no known interactions when it comes to taking paracetamol. Make sure that you mention in your consultation if you are taking lithium, medicines for the treatment of epilepsy, medicines to stop blood clotting (anti-coagulants), disulfiram, ciclosporin, oral contraceptives, cimetidine or fluorouracil.
