Fourteen patients of approximately 5,000 taking PAS imi this institution acquired a severe hypersensitivity to the drug. The reaction began 15 to 43 days after the beginning of therapy and all cases developed fever (100.2 to 105#{176} F.), rash and pruritus (table 1). The rash involved the face, neck, and extremities in the milder cases and was generalized in the severer ones. Usually it was er...
