1 in 4 ‘Biological’ Drugs Get Safety Warnings

Safety warnings have been issued for 1 out of 4 newer “biological” drugs, a study has found. The warnings were in response to serious side effects. These drugs are made from living materials. They often aim to boost the immune system. The study looked at U.S. and European drug approvals from 1995 through 2007. Safety warnings were issued through June 2008 for nearly 24% of the drugs. They included arthritis, cancer and heart failure drugs. The Associated Press wrote about the report October 22. It was in the Journal of the American Medical Association.
