Johnson & Johnson agreed to resolve criminal and civil probes into the marketing of Risperdal, an antipsychotic drug, and other medicines by paying more than $2.2 billion, one of the largest U.S. health-fraud penalties. J&J's Janssen unit will plead guilty to a misdemeanor criminal charge over misbranding Risperdal for uses not approved by the Food and Drug Administration, including treating elderly patients with dementia. Under a plea agreement announced today, Janssen will pay a $334 million fine and forfeit $66 million.
