CHICAGO (Reuters) - Walgreen Co said on Wednesday that it is marketing a combination of its clinics, pharmacies and other services to businesses looking to save on employee healthcare costs.

Walgreen, best known for the thousands of drugstores it has across the United States, also runs hundreds of health clinics in stores and at corporate offices.

The company, which is set to discuss the plan at its annual meeting on Wednesday, said its "Complete Care and Well-Being" program should cut employers' health care and prescription costs. The program also offers employees, dependents and retirees a 15 percent discount on Walgreens brand merchandise at its

stores.

The plan comes more than two years after Wal-Mart Stores Inc changed the retail pharmacy landscape by offering $4 monthly prescriptions on many generic drugs. Since then, Walgreen, CVS Caremark Corp, Rite Aid Corp, supermarkets and others have introduced their own low-cost generic drug plans. CVS also has its own line of clinics.

Employees can visit physicians, nurse practitioners, physician assistants, nurses, pharmacists and other health care workers at Walgreen's clinics at businesses, while the company's in-store Take Care clinics are staffed by nurse practitioners and physician assistants.
