Publisher's Synopsis
Nitrofurantoin
When taken appropriately, nitrofurantoin may effectively treat bacterial infections of the urinary tract. Antibiotics, including nitrofurantoin, are a class of drugs. Successful treatment depends on the elimination of infection-causing microorganisms.
Nitrofurantoin, like other antibiotics, is useless against viruses like the common cold and the flu. Taking antibiotics when they aren't required raises the probability that you'll get an illness down the road that can't be cured with antibiotics.
