Black box warnings are assigned to prescription drugs by the U.S. Food and Drug Administration (FDA) to alert of serious sides effects, such as injury or death. The smoking cessation drug, Chantix, previously had one of these black box warnings attached to it, but that warning has since been removed. This transition from a “dangerous drug” to a non-dangerous drug raises various important regulatory concerns regarding the marketing of this drug and other popular prescription drugs as well as the role of the FDA in regulating “dangerous” drugs.
