Adverse hepatic reactions to nitrofurantoin therapy are well reported and range from acute cholestatic or hepatitic injury to chronic active hepatitis [R. G. Penn & J. P. Griffin (1982) Br. Med. J., 284, 1440-1442]. Neurological side-effects, predominantly sensorimotor peripheral poly-neuropathy, have also been documented [R. G. Penn & J. P. Griffin (1982)]. We report the first case of combined neurological and hepatic reaction to nitrofurantoin; this occurred during repeated treatment with the drug.
