Thalidomide never entirely disappeared from use, however, and it was later found to benefit some leprosy patients. In 1998, after a complex safety monitoring system had been established to prevent further birth defects, thalidomide was approved for use in the United States for a complication of leprosy. The drug is also used to treat multiple myeloma, a cancer that affects the bone marrow.
