title: Cefoxitin-associated renal failure.
abstract: Two elderly women suffered an acute deterioration of renal function after treatment with cefoxitin sodium. One with stable chronic renal failure due to reflux nephropathy underwent a rapid deterioration of renal function which proved fatal. The other woman had rheumatoid arthritis and developed acute tubular necrosis after treatment with gentamicin and cefoxitin. All the data suggested that the antibiotic was responsible for the deterioration in renal function. The dose of cefoxitin should be reduced in patients with renal functional impairment. Cefoxitin should either be used with great caution or not prescribed in combination with aminoglycoside antibiotics.
