In the United States, a black box warning (also sometimes called a black label warning) is a type of warning that appears on prescription drugs that may cause serious adverse effects. It is so named for the black border that usually surrounds the text of the warning.
A black box warning means that medical studies indicate that the drug carries a significant risk of serious or even life-threatening adverse effects. The U.S. Food and Drug Administration (FDA) can require a pharmaceutical company to place a black box warning on the labeling of a prescription drug, or in literature describing it. It is the strongest warning that the FDA requires.
