CARDINAL HEALTH BRINGS RESOLUTION TO LITIGATION WITH DEA SETTLEMENT

DUBLIN, Ohio, May 15, 2012 – Cardinal Health today said it had agreed to a settlement with the Drug Enforcement Agency (DEA) that allows the company to bring resolution to ongoing litigation. Cardinal Health agreed to a two-year suspension of its Lakeland, Fla., distribution center’s DEA registration to ship controlled medicines from this facility and to improve certain anti-diversion procedures. The Lakeland distribution center will remain open, and all other operations at the facility will continue. The DEA also confirmed it is planning no further administrative actions at other Cardinal Health facilities.

“This agreement allows us to put this matter behind us, and just as important, will clear the way for a more productive dialogue about how we and others in the health care and regulatory community can work together to prevent the abuse and misuse of prescription drugs,” said George Barrett, chairman and CEO of Cardinal Health.

Cardinal Health will continue its efforts to help stop prescription drug abuse.
