St. Louis-based pharmacy benefits manager Express Scripts Inc. said Wednesday that it is suing Walgreen Co., arguing the drugstore chain is trying to lure away its customers.
The lawsuit alleges that Walgreen is telling Express Scripts plan members, and especially Medicare Part D beneficiaries, that they will not be able to fill their prescriptions at Walgreen pharmacies unless they leave Express Scripts and switch to a new pharmacy benefits management plan. Express Scripts said this violates the contract between the two companies.
Express Scripts and Medco Health Services say their merger will help control prescription drug costs. But many prescriptions may only be available by mail, which may not sit well with some consumers.
You probably haven't heard of either Express Scripts or Medco Health Services, but their plans to merge in a $29 billion deal, announced last month, may have an impact on your pocketbook.
