Phenacetin nephritis.

Prolonged ingestion of mixed analgesics containing phenacetin has been associated significantly with the development of a chronic interstitial nephritis frequently associated with papillary necrosis. This disease is frequently underdiagnosed. If an adequate history of headache and/or backache (of which most of these patients complain) is not taken, the central causative effect of phenacetin ingestion may never be appreciated.
