Abstract
A 68-year-old woman had reversible nonoliguric acute renal failure and yellow pigmentation of her skin and sclerae after ingesting phenazopyridine hydrochloride, 200 mg four times a day for six weeks. Although she began to recover renal function promptly after the drug therapy was discontinued, there was a further decline in her glomerular filtration rate after an oral cholecystogram and intravenous pyelogram. Phenazopyridineinduced acute renal failure is rare, but its early recognition is important so that additional nephrotoxicity from studies using roentgenographic contrast material may be avoided in patients with this problem.
