DRUG SAFETY: FDA Has Begun Efforts to Enhance Postmarket Safety, but Additional Actions Are Needed

There have been long-standing concerns regarding the Food and Drug Administration's (FDA) oversight of postmarket drug safety. In 2006, GAO reported that FDA had not clearly defined the roles of two offices involved in making decisions about postmarket safety--the Office of New Drugs (OND) and the Office of Surveillance and Epidemiology (OSE). GAO and others reported additional concerns such as limitations in the data FDA relies on to identify postmarket drug safety issues and the systems it uses to track such issues. This report examines the steps that FDA is taking to (1) enhance its processes for making decisions about the safety of marketed drugs, (2) improve access to data that help the agency identify drug safety issues, and (3) build its capacity to fulfill its postmarket drug safety workload.
