What is Nitrofurantoin?

We are often asked “What is Nitrofurantoin?”

Nitrofurantoin or Macrobid is a prescription medicine which is used to treat and prevent infections of the bladder (cystitis), kidney and other parts of the urinary tract (UTIs).

When Nitrofurantoin is taken, the body filters it out of your blood and into your urine. This is especially helpful if you have a urinary tract infection because it centralizes around the site of infection. However, this means that Nitrofurantoin won’t do anything for other types of infection.

Nitrofurantoin or Macrobid is available on prescription and either comes as capsules, tablets or a liquid that is consumed.

There are three types of Nitrofurantoin available –

Furadantin, microcrystalline form

Macrodantin, macrocrystalline

Macrobid, a continued release of macrocrystalline that is taken twice a day
