Definition
Thalidomide is a medication that has a complex history. It was originally used in the late 1950s and early 1960s as a sedative and to treat morning sickness in pregnant women. Tragically, it was found to cause severe birth defects. Today, thalidomide is used to treat certain cancers, such as multiple myeloma, and some skin conditions. Its use is strictly regulated, and it is never prescribed to pregnant women.
