What is Nitrofurantoin?

Nitrofurantoin is an antibiotic drug used to treat urinary tract infections (UTIs). It works by reducing the amount of bacteria in your body, thereby limiting the growth of a UTI. It is only available by prescription in the United States, but is available over-the-counter in some other countries.

Nitrofurantoin can be used to treat UTIs caused by Escherichia coli (E. coli), Klebsiella pneumoniae, and Proteus mirabilis. It is also commonly used for a type of infection called cystitis. Cystitis is often recurrent, meaning that it happens again and again.

Cystitis is inflammation of the bladder that can be caused by bacterial or non-bacterial infections. The most common cause of cystitis is E. coli. Nitrofurantoin is effective in treating cystitis caused by these bacteria, but not non-bacterial cystitis.

How Does it Work?

Nitrofurantoin works by killing the bacteria in your body that are causing your UTI. It is an antibiotic that stops bacterial growth in your bladder, urethra, and kidneys. This includes E. coli, which is the most common cause of UTIs. E. coli often lives in your digestive tract, but sometimes it can enter your urinary tract. When it does, it can cause a UTI.

Nitrofurantoin is not absorbed well into your bloodstream, so it stays in your urinary tract and bladder. That’s why it is good for UTIs in these areas of your body. It can help decrease symptoms of a UTI such as burning and urgency. It can also help prevent a UTI from getting worse and leading to kidney damage.
