Pfizer Inc. must pay $1.5 million in damages to a pharmacist who developed breast cancer after taking one of the company’s menopause drugs, a jury in Puerto Rico ruled.

Jurors in federal court in San Juan deliberated about 7 hours over two days before finding yesterday that Pfizer’s Wyeth subsidiary failed to properly warn Helen Rivera-Adams and her doctors about the health risks of its Prempro menopause medicine, one of her lawyers said in an interview.
