35 FDA-Approved Prescription Drugs Later Pulled from the Market since the 1970s
According to the FDA, a "drug is removed from the market when its risks outweigh its benefits. A drug is usually taken off the market because of safety issues that cannot be corrected, such as when it is discovered that the drug can cause serious side effects that were not known at the time of approval." The FDA also takes into account the number of people taking a drug being considered for removal so as to not harm those patients.
