Flagyl (metronidazole) is an antibiotic and antiprotozoal medication used to treat certain infections caused by anaerobic bacteria and parasites.
Common uses include:
- Bacterial vaginosis (BV)
- Trichomoniasis, a sexually transmitted infection
- C. difficile (C. diff) infections in some situations
- Dental and gum infections
- Abdominal or pelvic infections, including infections involving the intestines
- Amebiasis, caused by the parasite Entamoeba histolytica
- Giardiasis, caused by the parasite Giardia
- Certain skin, bone, joint, and surgical-site infections involving susceptible anaerobic bacteria
- As part of combination therapy for H. pylori, the bacteria associated with some stomach ulcers
Flagyl does not treat viral illnesses such as colds or influenza.
A common precaution is to avoid alcohol while taking metronidazole and for at least 3 days after the final dose, because the combination may cause nausea, vomiting, flushing, headache, or abdominal discomfort.
If you'd like, I can also explain Flagyl 500 mg uses, common side effects, and what to avoid while taking it.
