Nitrofurantoin neuropathy: a forgotten adverse effect.

Abstract

Nitrofurantoin is a widely prescribed antibiotic used to treat uncomplicated lower urinary tract infections. Unknown in the obstetric and gynecologic literature is the complication of peripheral neuropathy as an adverse effect. We describe a patient who developed a severe sensory neuropathy after taking nitrofurantoin intermittently and then continuously over a 7-year period. She recovered almost completely after its discontinuation. Peripheral neuropathy is a rare and potentially reversible adverse effect, unreported in the obstetric and gynecologic literature, and commonly unrecognized by physicians who prescribe it.
