Commonly, it is prescribed for bacterial vaginosis, pelvic inflammatory disease, and infections of the stomach, skin, joints, and respiratory tract. Additionally, it is used to manage amoebic dysentery and liver abscesses caused by Entamoeba histolytica. In dental care, metronidazole helps treat gum infections and dental abscesses. It is also employed in combination with other medications to eradicate Helicobacter pylori, a bacterium associated with stomach ulcers. Its ability to penetrate tissues makes it valuable in treating brain abscesses and other deep-seated infections.
