What Is Metronidazole?
Metronidazole is an antibiotic and antiprotozoal medication used to treat infections caused by anaerobic bacteria and certain parasites. It works by stopping the growth of microorganisms and helping the body eliminate infection.
How Does Metronidazole Work?
Metronidazole enters microbial cells and interferes with their DNA synthesis, which leads to the death of bacteria or parasites. This helps control and clear the infection.
Systemic infections may sometimes be associated with urinary symptoms. Learn more about hematuria (blood in urine) .
