The staff pharmacists at my hospital spend most of their time sitting to enter orders and answer the phone. They only get up to check Pyxis fills, cart fills, crash carts, anesthesia trays, and IVs, and to do stat orders and controlled substance fills. They also have to go up to the floors to respond to Code Blues or to do aminoglycoside dosing. They also get 45 minutes have an uninterrupted lunch break.
As for the clinical pharmacists, it depends on what their duty is (medication safety, transitional care, critical care, etc.).
