CVS Caremark Corp., the largest U.S. provider of prescription drugs, was sued over claims it used confidential prescription information to push products on behalf of pharmaceutical makers.
CVS violated the privacy and rights of consumers by sending letters to customers’ physicians that promoted specific medications, according to a complaint filed March 7 in state court in Philadelphia. CVS allegedly identified consumers by name, date of birth and medications taken, drawing on information obtained through CVS pharmacy services.
