We don't want to deny this drug to people. Thalidomide was never sold in the United States, although some Americans got it abroad or in research trials. An FDA scientist spotted early signs of toxicity that the original manufacturer denied, and blocked U.S. sales long enough for the danger to be proved overseas. But thalidomide is staging a comeback, though not as a morning sickness treatment. The FDA is considering whether to approve it to treat painful sores that afflict leprosy patients.
Scientists think thalidomide works by altering the immune system.
In addition to leprosy, the drug may work against symptoms of AIDS, cancer and tuberculosis. But critics say there is an inevitable and terrible downside. To counter that possibility, the manufacturer says women taking thalidomide would be required to use two forms of birth control. Inc. All Rights Reserved.
