fen-phen controversy

The fen-phen controversy involved a popular weight-loss drug combination—fenfluramine and phentermine—used in the 1990s. While these drugs helped many shed pounds, they were linked to serious health risks, especially heart valve damage and pulmonary hypertension. Reports of adverse effects led to widespread recall in 1997 and lawsuits against manufacturers. The controversy highlighted the importance of rigorous drug safety testing and post-marketing surveillance, increasing awareness about potential medication risks. Ultimately, it underscored the need for careful regulation and monitoring of pharmaceuticals after approval.
