Caremark Rx is launching a credit card program that offers users incentives for managing prescription drug costs. The credit card will be available to all individuals covered by a Caremark-administered prescription drug plan or enrolled in one of Caremark's discount card programs. Cardholders will receive reward points each time they purchase a generic drug or a preferred brand prescribed drug, as determined by the cardholder's pharmacy plan formulary. Points also will be awarded to cardholders who refill existing prescription orders using Caremark's Web site or automated phone system. The points can be redeemed through Bank of America's WorldPoints program for merchandise, travel, or cash back.
