On Wednesday, August 25, 2021, Epic's e-prescribing vendor, Surescripts will sunset a number of specific potency unit codes. For example, tube, pen, inhaler nor vial will no longer be available options for units when prescribing. 

The unit selection/search will give only the allowed units for the medication during order entry. If you are attempting to refill a medication with expired units, a new order validation hard stop will prevent any order or reorders with expiring units from being signed until an alternative dispense unit is selected. If the order validation appears, an equivalent supply quality should be chosen.
