    Thalidomide in Canada

    The drug thalidomide was developed in Germany in the 1950s and was first available in Canada in 1959. It was originally prescribed as a sedative but was also given to pregnant women for nausea relief. By the end of 1962, however, thalidomide had been withdrawn from markets worldwide, following reports of babies born with severe birth defects. The tragic consequences led to changes in drug licensing and regulation in Canada and other countries, including the US and UK. More than 10,000 children around the world were born with deformities caused by thalidomide; many died within months of birth. In Canada, more than 100 children were born with congenital malformations caused by thalidomide. In the 21st century, thalidomide was approved by Health Canada for the treatment of leprosy, multiple myeloma, and some autoimmune diseases.

    The Craft of Motion Picture Making
