Metronidazole is a widely used antibiotic and antiprotozoal medication that has been prescribed to millions of people around the world. It is effective against a variety of infections, including bacterial vaginosis, pelvic inflammatory disease, and infections caused by susceptible organisms such as Giardia and Trichomonas.
