Drugmaker Allergan has agreed to pay the federal government and several states $13 million to settle whistleblower claims that it provided business consulting and services to doctors as a way of encouraging them to prescribe the company's eye care products.

The settlement was announced June 29 in a joint statement by Pittsburgh firm Pietragallo Gordon Alfano Bosick & Raspanti and Chicago law firm Goldberg Kohn. U.S. District Judge Mark Kearney issued a subsequent order acknowledging the settlement and dismissing the case.

The case was filed in 2009 in the U.S. District Court for the Eastern District of Pennsylvania under the False Claims Act by two Philadelphia-area ophthalmologists, represented by the firms.
