How did the 1962 amendment to the Food, Drug, and Cosmetic Act change drug regulation?

The 1962 amendment to the Federal Food, Drug, and Cosmetic Act was a critical legislative response to the thalidomide tragedy, which caused severe birth defects in thousands of infants.12

This amendment significantly strengthened drug regulation by introducing two major requirements:

• Proof of Effectiveness: Manufacturers were required to provide scientific proof that all new drugs introduced for sale were effective for their intended use. This requirement was made retroactive to drugs introduced since 1938.3
• Advertising Oversight: The U.S. Food and Drug Administration (FDA) was granted authority to regulate the advertising of prescription drugs, helping to curb the quackery and misleading claims often associated with unproven medical products.3

By mandating evidence of efficacy and expanding regulatory control, the 1962 amendment provided essential protections against the marketing of ineffective or potentially harmful substances, reinforcing the ethical principle that public safety must take precedence over the commercial interests of drug manufacturers.32
