Metronidazole Tablet is a widely used prescription medicine that belongs to the class of antibiotics and antiprotozoal agents.

What is a Metronidazole Tablet?

Metronidazole Tablet is an antimicrobial drug that works by disrupting the DNA of harmful bacteria and protozoa, preventing them from multiplying.

It is available in different strengths and can be taken orally or in other forms, depending on the infection type and severity.

Common Uses of Metronidazole Tablet
