Public Citizen has been assessing the quality and efficacy of drugs and devices since its founding in 1971. We use the law, petitions, and letters to monitor the FDA and coax the agency into action. Our actions have contributed to many drugs being pulled off the market. Public Citizen has also been instrumental in getting “black box” and other warnings on drugs. Our advocacy work on this drug is available below.
