Flagyl (Metronidazole)

Metronidazole General Information

Flagyl (Metronidazole) is used to kill any bacteria in the body that are causing infection. This medication is effective against anaerobic bacteria and certain parasites. Anaerobic bacteria are single-celled. They are living organisms that thrive in environments in which there is little oxygen. These bacteria may cause disease in the abdomen, pelvis, and liver. This medication selectively blocks some of the functions within the bacterial cells. It will also block the parasites that may result in their death.

How does Flagyl (Metronidazole) work?

Flagyl (Metronidazole) prevents nucleic acid synthesis. It is by disrupting the DNA of microbial cells. This function only happens when this drug is partly reduced. And with this decrease, it frequently occurs only in anaerobic bacteria and protozoans. It has relatively little effect on human cells or aerobic bacteria.

This drug only treats certain bacterial and parasitic infections. This will not work for a viral infection such as flu or a common cold.
