Drug-induced blood disorders

Abstract
A case-history study of drug-induced blood disorders (pancytopenia, hemolytic anemia, thrombocytopenia and granulocytopenia) was carried out at the Group Health Cooperative of Puget Sound, a health maintenance organization with > 200,000 members, for the 10-yr period from 1972-1981. During this time, only 26 instances of hospitalization for such disorders were thought to be definitely, probably or possibly due to drugs other than antitumor agents. The rate was of the order of 1/100,000 person-years at risk. Only quinidine/quinine and sulfa-containing drugs were implicated in > 1 case.
