[Phenacetin and renal damage: a follow-up study (author's transl)].

Forty-five persons, known between 1962 and 1965 to have taken phenacetin-containing analgesics in large amounts but having normal renal function without urinary infection, were re-examined in 1973. Eleven had died in the meantime, two in renal failure. Of the remaining 34 all but three had normal renal function, although some of them had continued to take large amounts of phenacetin-containing drugs. The results confirm the view that morbidity and mortality of long-standing phenacetin abuse is probably very low.
