Overview of Flagyl:

Flagyl (metronidazole) is a common antibiotic medication that is used to treat a variety of infections caused by certain types of bacteria and parasites. It is commonly prescribed by healthcare providers due to its effectiveness in combating these infections.

Flagyl works by entering the cells of bacteria and parasites, where it interrupts their DNA synthesis, leading to their eventual death. This mechanism of action makes Flagyl effective in treating infections such as:

  • Bacterial vaginosis
  • Trichomoniasis
  • Amebiasis
  • Giardiasis
  • H. pylori infections

Flagyl is available in various forms, including tablets, capsules, and intravenous solutions, to cater to different patient needs. Your healthcare provider will determine the appropriate dosage and duration of treatment based on your specific condition and medical history.
