Study: Side effects emerge after approval for many US drugs

Associated Press ------- Almost one-third of new drugs approved by U.S. regulators over a decade ended up years later with warnings about unexpected, sometimes life-threatening side effects or complications, a new analysis found. The results covered all 222 prescription drugs approved by the U.S. Food and Drug Administration from 2001 through 2010. The researchers looked at potential problems that cropped up during routine monitoring that’s done once a medicine is on the market. The 71 flagged drugs included top-sellers for treating depression, arthritis, infections and blood clots. Safety issues included risks for serious skin reactions, liver damage, cancer and even death. “The large percentage of problems was a surprise,” and they included side effects not seen during the review process, said Dr. Joseph Ross, the study’s lead author and an associate professor of medicine and public health at Yale University. While most safety concerns were not serious enough to prompt recalls, the findings raise questions about how thoroughly drugs are tested before approval, said drug safety expert Thomas Moore. But Ross said the results suggest that the FDA “is kind of doing a great job” at scrutinizing drugs after approval. To get more in depth information click on the picture below to read the article.
