What is nitrofurantoin used to treat?

Nitrofurantoin is used to treat uncomplicated urinary tract infections. Nitrofurantoin should treat the symptoms associated with an uncomplicated UTI and cure the infection.

How does nitrofurantoin work?

Nitrofurantoin is an antibiotic. Nitrofurantoin works by interfering with the vital processes (formation of cell walls, DNA and RNA synthesis) in bacteria that keep them alive. Without these vital processes, the bacteria die. Nitrofurantoin is also bactericidal in urine, meaning it kills infection-causing bacteria that can be present in urine. Nitrofurantoin is specific to the bacteria that cause UTIs and therefore should only be taken for those infections.

What are common side effects of nitrofurantoin?

How long does it take for nitrofurantoin to work?

Most people will begin to feel better after the first 1-2 days of taking nitrofurantoin. Because nitrofurantoin is an antibiotic, it is important to finish the prescription given to you, even if you feel better. If you stop taking nitrofurantoin too soon, your infection may become more difficult to treat and could even become resistant to antibiotics.
