Patient summary

This antibiotic is indicated to target urinary tract infections, developed to alleviate symptoms of cystitis and to support clearing bacterial bladder infections.

Mechanism of action

Nitrofurantoin is a bactericidal antibiotic that acts by damaging bacterial DNA. It is highly specific to the urinary tract due to its rapid excretion into urine upon oral administration.

Pregnancy and breastfeeding

Pregnancy: Use with caution, avoid at term. Breastfeeding: Confirm breastfeeding suitability with a qualified clinician or pharmacist before use.

Nitrofurantoin is an antibiotic that concentrates in the urine, so it is used for cystitis and other urinary tract infections and, at a low dose, to prevent infections that keep coming back. It comes in 50 mg and 100 mg strengths; the original brands are Macrodantin and Macrobid.

Tell your doctor first if you have ever had kidney disease, or jaundice or other liver problems while taking nitrofurantoin, and if you have anaemia, diabetes, lung problems, nerve damage or G6PD deficiency (MedlinePlus).
