PHILADELPHIA (AP) -- Drug maker Cephalon has completed a previously announced $425 million civil settlement with federal authorities over off-label drug marketing.

Federal authorities in Philadelphia say Cephalon Inc. marketed three drugs for uses other than what they were federally approved for. Cephalon disclosed the tentative settlement last November.

Authorities say Cephalon marketed one of the drugs, Actiq, for maladies including migraines and injuries. But authorities say the fentanyl lollipop is a highly addictive narcotic approved only for certain cancer patients.

The suburban Philadelphia company has signed an agreement to plead guilty to one count of distribution of misbranded drugs.
