While taking

Nitrofurantoin, an antibiotic, eliminates bacteria that cause urinary tract infections. Antibiotics will not work for colds, flu, or other viral infections.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Nitrofurantoin comes as a capsule and a liquid to take by mouth. Nitrofurantoin usually is taken two or four times a day for at least 7 days. Shake the oral liquid well before each use to mix the medication evenly. Take it with a full glass of water and with meals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take nitrofurantoin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
