What is Metronidazole 400mg?

Metronidazole is an antibiotic used in the treatment of bacterial infections in the body. It can be used to treat a severe dental abscess.

It works very well to treat infections in the mouth, gums, abdomen and pelvic area which are caused by micro-organisms called protozoa and anaerobic bacteria. (Anaerobic means the bacteria don’t need oxygen to survive and multiply.)

How does Metronidazole work?

Metronidazole is part of a group of medicines called anti-infective agents which work to kill the bacteria that cause infections. It cannot kill a virus.

It’s important to only take antibiotics when they are prescribed to you as they may become ineffective in the future if you take them when you don’t need to.

How do you take Metronidazole?

Always take the antibiotic Metronidazole as directed by your dentist or pharmacist and read the patient information leaflet in full before taking it.  

The dosage for dental infections is one tablet three times a day for a total of 7 days. Swallow the tablet whole with water, during or just after a meal. Space the doses out evenly and be sure to complete the course of treatment.

It’s best not to drink alcohol whilst taking this medication or for 72 hours after finishing your treatment. This is because alcohol can interact with Metronidazole to cause side effects such as nausea and vomiting, stomach pain, hot flushes, palpitations and headaches.

How effective is Metronidazole?

Metronidazole tablets are clinically proven antibiotics for tooth infection or gum infection.

You should always make sure you see your dentist if you suspect you have a dental infection as it may get worse if not treated correctly.

You can help to prevent further dental infections by making sure you practice good oral hygiene. Brush your teeth twice a day and use dental floss and mouthwash as recommended.
