To the editor: We report severe renal failure and nephrotic syndrome in three patients taking zomepirac sodium, a nonsteroidal anti-inflammatory drug.
A 46-year-old woman who had been taking zomepirac sodium for 2 months for headache developed renal failure and nephrotic syndrome. Laboratory studies showed creatinine, 3.9 mg/dL; blood urea nitrogen, 90 mg/dL; albumin, 1.4 mg/dL; and 24-hour urine protein, 14.5 g. Renal biopsy showed tubular cell vacuolization with sloughing of tubular cells and interstitial edema with a pleomorphic infiltrate. Results of immunofluorescent studies were normal. Zomepirac was withdrawn and prednisone, 60 mg/d, was instituted. Renal failure and nephrotic syndrome resolved
