NAME - thanks for your message. From a strictly speaking mileage standpoint, the closest pharmacy off campus is probably CVS Coliseum Drive:

CVS, 606 Coliseum Dr. Winston Salem, NC 27106 

If your Deac doesn't have a car and would need to take the campus shuttle, the CVS Robinhood Road is accessible via the Hanes Mall River Birch shuttle (they would get off at River Birch and cross the street to the CVS).

CVS, 3325 Robinhood Rd., Located In Mount Tabor Place Winston Salem, NC 27106

Hope that helps,
Betsy
