Why this is used

Nitrofurantoinis used to treat urinary tract infections. Nitrofurantoin is in a class of medications called antibiotics. It works by killing bacteria that cause infection. Antibiotics will not work for colds, flu, or other viral infections.

How to take it

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. . Take it with a full glass of water and with meals. Try to take nitrofurantoin at the same times every day. 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. Shake the liquid well before each use to mix the medication evenly. Use a dose-measuring spoon or cup to measure the correct amount of liquid for each dose; not a household spoon. You should begin to feel better during your first few days of treatment with nitrofurantoin. If your symptoms do not improve or if they get worse, call your doctor. Take nitrofurantoin until you finish the prescription, even if you feel better.
