A group of labor unions is launching a campaign that accuses CVS Caremark Corp. of violating patient privacy and improperly pushing doctors to prescribe a costly prescription drug.
Change to Win, a group of unions that represents about six million workers, said CVS’s pharmacy benefits management business has been urging doctors via a letter to add Merck & Co. diabetes drug Januvia to specific patients’ treatments. The letter, obtained by the union group, said CVS identified the diabetes patients through a review of prescription-drug claims processed by its Caremark unit.
A line at the bottom of the letter says Merck paid for the mailing. Neither Merck nor CVS would say how much Merck paid, and the drug maker also declined to say whether the mailing boosted Januvia sales.
