Patient summary

Nitrofurantoin 50mg and 100mg tablets, used for cystitis and urinary tract infection. Bacterial flavoproteins reduce it to reactive intermediates.

Mechanism of action

Nitrofurantoin is reduced by bacterial flavoproteins to reactive intermediates that inactivate or alter bacterial ribosomal proteins and other macromolecules. This action inhibits aerobic energy metabolism and protein synthesis, resulting in bactericidal activity specifically within the urinary tract.

Pregnancy and breastfeeding

Pregnancy: Can be used if benefits outweigh risks, but avoid at term due to risk of neonatal haemolytic anaemia. Breastfeeding: Can be used with caution during breastfeeding.
