What is Metronidazole?
Metronidazole, sold under the brand name Flagyl, is an antibiotic effective against bacterial and parasitic infections (protozoal).
Since its approval in 1960 in France, Metronidazole has been used widely throughout Europe to effectively treat various infections.
euroClinix offers Metronidazole as 400 mg tablets specifically for bacterial vaginosis and trichomoniasis. Bacterial vaginosis is a common vaginal infection that can cause symptoms like a strong odour and a change in vaginal discharge. Trichomoniasis is an STI caused by the parasite trichomonas vaginalis, a protozoan infection.
How does Metronidazole work?
Containing the active ingredient of the same name, Metronidazole works by directly attacking the bacteria or virus you are infected with. Metronidazole is used primarily for some bacterial and parasitic infections.
When this medicine is taken, it disrupts the DNA of the harmful organisms, causing them to die. Because it kills these germs directly rather than just stopping their growth, this medicine is effective in treating anaerobic infections like bacterial vaginosis and trichomoniasis, which thrive in low-oxygen environments.
By removing the infection at the source, Metronidazole not only offers relief from symptoms, but effectively cures your condition.
What are the benefits of Metronidazole?
Metronidazole tablets have many uses and offer various health benefits. Here are some of the most notable:
- Targets infections directly - kills harmful bacteria and parasites directly, curing the infection at the source.
- Treats bacterial and parasitic infections - effective both for bacterial infections, such as bacterial vaginosis, and parasitic infections, such as trichomoniasis.
- Symptom relief - helps relieve symptoms like unusual discharge, itching and painful urination.
- Reduces the risk of complications - by treating your infection, you reduce the risk of complications such as pelvic inflammatory disease and infertility.
How effective is Metronidazole?

- Bacterial vaginosis - one clinical study found this treatment to be 88% effective in the treatment of bacterial vaginosis*.

Product works quite well, the only one downside - it is on the expensive side. If you end up using highest dosage, it’s £75 for a week of treatment...
AldisOne day in to course and huge improvement. Hope this is what I think at end of course.
