Drug-induced lupus erythematosus

Medical condition

Drug-induced lupus erythematosus is an autoimmune disorder caused by chronic use of certain drugs. These drugs cause an autoimmune response producing symptoms similar to those of systemic lupus erythematosus (SLE). There are 38 known medications to cause DIL but there are three that report the highest number of cases: hydralazine, procainamide, and quinidine. While the criteria for diagnosing DIL has not been thoroughly established, symptoms of DIL typically present as muscle pain and joint pain. Generally, the symptoms recede after discontinuing use of the drugs.
