What is Flagyl used for?

Flagyl

Flagyl tablets contain 250 mg or 500 mg of metronidazole.
Metronidazole is an antibiotic effective against bacterial infections (vagina, stomatch, skin, joints, liver and respiratory tract) and certain parasites.

Giardia lamblia and ameba are intestinal parasites that cause diarrhea and abdominal pain.

Trichomonas is a vaginal parasite that causes vaginitis.
Metronidazole selectively blocks some functions within the bacterial cells and the parasites resulting in their death.

Do not break or chew Flagyl ER; Swallow it whole. Crushing the tablet may cause too much to be released at one time.
Skipping doses may increase your risk of further infection that is resistant to antibiotics. Metronidazole will not treat a viral infection such as the common cold or flu.
To be sure this medication is not causing you harmful effects; your blood may need to be tested often. Your liver function may also need to be tested. Visit your doctor regularly.
