You should not use this medication if you are allergic to metronidazole, or if you are in the first trimester of pregnancy. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
Before taking metronidazole, tell your doctor if you are allergic to any drugs, or if you have:
- liver disease;
- a stomach or intestinal disease such as Crohn's disease;
- a blood cell disorder such as anemia (lack of red blood cells) or leukopenia (lack of white blood cells);
- epilepsy or other seizure disorder; or

If you have any of these conditions, you may need a dose adjustment or special tests to safely take this medication.
Metronidazole can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take metronidazole (Flagyl)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Take the extended-release metronidazole tablet (Flagyl ER) on an empty stomach, at least 1 hour before or 2 hours after eating a meal.
Do not crush, chew, or break an extended-release tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also 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 harmful effects, your blood may need to be tested often. Your liver function may also need to be tested. Visit your doctor regularly.
This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using metronidazole.
Store at room temperature away from moisture and heat.
