The FDA has been maintaining its influence on the American consumer for a century. One of his most famous achievements was the rejection of thalidomide, a widely used drug that was later revealed to cause significant birth defects. Medicine; It was marketed in Europe in the late 1950s as a way to suppress morning sickness in pregnant women. Doctors at that time thought that the drugs given to the mother could not affect the fetuses. Thus, no attempt has been made to test its safety for developing babies. When thalidomide producers tried to get FDA approval to sell drugs in the US in 1960, FDA inspector Frances Kelsey slowed the process by demanding that the company do more safety work. The following year, reports of thousands of babies born with serious birth defects began to emerge. This incident increased confidence in the FDA and encouraged the transition of changes that strengthen the FDA's drug review process.
