Nitrofurantoin is an antibiotic used specifically to treat urinary tract infections.
It is commonly used for:
• Acute urinary tract infections: Treats infections of the bladder caused by susceptible bacteria.
• Recurrent urinary tract infections: Sometimes used at a low dose over a longer period to help prevent repeated infections.
• Uncomplicated cystitis: Clears bladder infections in patients without complicating factors.
Nitrofurantoin works by damaging the DNA and proteins of bacteria once it becomes concentrated in the urine.
Inside susceptible bacterial cells, it is converted into reactive compounds that interfere with multiple bacterial processes, including DNA replication and protein production.
Because this multi-target action makes it difficult for bacteria to develop resistance, and because the medicine reaches high concentrations specifically in the urinary tract, nitrofurantoin is particularly effective for treating urinary tract infections.

Frequently asked questions
Nitrofurantoin usually starts working within a few hours, but symptoms of infection may take 2 to 3 days to improve. It is important to complete the full course of treatment as prescribed by the doctor.
Inform your doctor if you have kidney or liver disease, anemia, diabetes, lung disease, or a history of allergic reactions to antibiotics. Avoid alcohol, stay hydrated, and take medication with food to reduce stomach upset.
No, you should complete the full course of Nitrofurantoin even if you feel better. Stopping the medication too early may allow the infection to return or contribute to antibiotic resistance.
Nitrofurantoin should be used with caution in patients with kidney or liver disease, as it may worsen these conditions. A doctor should evaluate the risks before prescribing it.
