GlaxoSmithKline and Sanofi are being sued alongside Grünenthal by Americans born half a century ago with birth defects they allege were caused by the drug thalidomide, in a fresh twist that draws new pharmaceutical groups to the long search for responsibility...The legal action claims the drug was more widely used in the US than previously thought and may have caused thousands of birth defects in children, despite the long-standing belief that the Food and Drug Administration’s refusal to authorise thalidomide limited side-effects to a few cases. [also refers to Grünenthal]
