Patient Reviews: How Metronidazole Has Made a Difference

What is Metronidazole?

Metronidazole is an antibiotic used to treat certain bacterial infections. It is also used to treat certain protozoal infections, including some types of amebiasis and trichomoniasis.

Metronidazole belongs to a group of drugs called antiprotozoal agents, which kills certain types of bacteria and parasites. It comes in the form of oral tablets or a topical vaginal gel called Zidoval.

It works by stopping the growth of organisms in the body and by reducing the production of molecules called free radicals, which can damage cells. This can help to reduce the symptoms of bacterial and parasitic infections.

The tablets stop the growth of the bacteria (or parasite) that is initiating the infection. This prevents the cells' ability to reproduce, stopping the infection from spreading and giving the immune system a better chance of fighting the infection.

When taking any course of antibiotics, it is important to complete the course of treatment, even if you feel better or the infection has cleared. Stopping Metronidazole  too early can cause your infection to return.

Understanding Bacterial Vaginosis:

Metronidazole is a medication often prescribed to treat bacterial infections of the vagina, stomach, skin, joints, and respiratory tract.

Vaginal Bacterial Vaginosis (BV) is a common vaginal infection, affecting 1 in 3 women in the UK.

Though not considered an STI, BV can be initiated through sexual intercourse and may even be transmitted from one woman to another.

What Triggers Bacterial Vaginosis?

The potential causes of BV encompass:

  • Using scented products in or around the vagina
  • Changing sexual partners
  • Vaginal pH changes during menstrual cycles
  • Washing underwear with potent detergents
  • Using an IUD for contraception

Is Bacterial Vaginosis Comparable to Thrush?

BV is often confused with thrush due to the similar symptoms.

The distinction lies in the vaginal discharge's consistency and odor.

Unlike thrush’s thick, odorless discharge, BV's discharge is often thin, watery, and foul or fishy-smelling.

If you detect a change in vaginal discharge, consult an online prescriber or a pharmacist.

Treating Bacterial Vaginosis Online Using Metronidazole

Metronidazole may be requested online if you have been diagnosed with bacterial vaginosis and successfully treated by your GP. You might be eligible for online BV treatment if you:

  • Received a diagnosis or had a positive home test for bacterial vaginosis
  • Were prescribed Metronidazole and successfully treated the infection
  • Have symptoms such as fishy odor and possibly thin discharge

Metronidazole Dosing Regimen

The typical dosing regimen for metronidazole used to treat bacterial vaginosis (BV) is 500 mg twice daily (morning and evening) for seven days.

Depending on the individual patient, doses may range from 250 mg to 1000 mg. 

It is important to always take metronidazole exactly as prescribed by your healthcare provider. Do not take a double dose if you miss a dose. If you have any questions about dosing or any other aspects of treatment, contact your healthcare provider.

What Should I Do If I Forget to Take Metronidazole?

If you forget to take Metronidazole 400mg, take it as soon as you remember.

If it is near the time of your next dose, skip the missed dose and continue taking Metronidazole as you normally would.

To help you remember when to take your next dose of Metronidazole, put your medicine in a place where you are most likely to remember it, or a place where you will see it to prompt you to take it.

Alternatively, you could set a reminder on your phone or smart device which will prompt you near the time of your next dose of Metronidazole.

To learn more on how to take Metronidazole visit the NHS website.

How Will I Know If Metronidazole 400mg Is Safe for Me?

By filling out our confidential medical questionnaire, our prescribers will be able to determine whether Metronidazole is safe for you.
