Several case-control studies suggest an association between analgesic use and increased risk of chronic renal disease, but few cohort studies have examined this association.


To determine whether analgesic use is associated with risk of renal dysfunction.


Cohort study of analgesic use data from the Physicians' Health Study, which lasted 14 years from September 1982 to December 1995 with annual follow-up.


A total of 11 032 initially healthy men who provided blood samples and self-report of analgesic use.


Elevated creatinine level defined as 1.5 mg/dL (133 micromol/L) or higher and a reduced creatinine clearance defined as 55 mL/min (0.9 mL/s) or less, and self-reported use of acetaminophen, aspirin, and other nonsteroidal anti-inflammatory drugs (never [<12 pills]; 12-1499 pills; 1500-2499 pills; and >/=2500 pills).


A total of 460 men had elevated creatinine levels (4.2%) and 1258 had reduced creatinine clearance (11.4%). Mean creatinine levels and creatinine clearances were similar among men who did not use analgesics and those who did, even at total intakes of 2500 or more pills. In multivariable analyses adjusted for age; body mass index; history of hypertension, elevated cholesterol, and diabetes; occurrence of cardiovascular disease; physical activity; and use of other analgesics, the relative risks of elevated creatinine level associated with intake of 2500 or more pills were 0.83 (95% confidence interval [CI], 0.50-1.39; P for trend =.05) for acetaminophen, 0.98 (95% CI, 0.53-1.81; P for trend =.96) for aspirin, and 1.07 (95% CI, 0.71-1.64; P for trend =.86) for other nonsteroidal anti-inflammatory drugs. No association was observed between analgesic use and reduced creatinine clearance.


Moderate analgesic use in this cohort study of initially healthy men was not associated with increased risk of renal dysfunction.
