What is Metronidazole?
Metronidazole 400mg tablets (also referred in this information as Metronidazole) is an effective clinical antibiotic that belongs to a group of medications called anti-infective agents.
Metronidazole may be used to treat mouth and dental infections caused by bacteria such as ulcerative gingivitis, wisdom tooth infection or dental abscesses. Metronidazole can also be used in the treatment of bacterial infections occurring after surgery alongside a multitude of conditions. These include infections in the stomach, blood, brain and pelvic area.
For further information on Metronidazole, please see the Patient Information Leaflet here.
How it works
Metronidazole, like all anti-infective agents, works by stopping the growth and spread of the bacteria causing oral infections. While taking antibiotics, it is important to always finish the entire course of Metronidazole for as long as your doctor has prescribed. Even if you feel better, you will be at an increased risk of re-occurring infection if treatment is finished prematurely.
With serious swelling of dental infections, the medicine should be working within a few days; It may take longer, up to a week, before the symptoms significantly improve.
It is recommended to take another test around 3 months after treatment is completed and to abstain from sex until completing the course of treatment. This is because young adults who were tested positive for chlamydia had an increased risk of catching it again.

Most healthy adults and adolescents can take Metronidazole. However, there are some circumstances where Metronidazole is unsuitable to treat an infected dental abscess.
