FDA Issues Consumer Advisory for Dietary Supplements Containing Kava

On March 25, 2002, the Food and Drug Administration (FDA) issued an advisory notifying consumers that kava-containing dietary supplements may be associated with severe liver injury. The FDA reported that kava-containing products have been associated with liver-related injuries, including hepatitis, cirrhosis, and liver failure, in over 25 reports of adverse events in other countries. In the U.S., FDA received a report of a previously healthy young female who required liver transplantation, as well as several reports of liver-related injuries.
