The alternating dosing option is not accepted in Pharmacy and cannot be written for inpatients. To order different dosing on alternating days, write two (2) orders with QOD frequencies, one for each dose, and set the start dates and times as appropriate. See Defining Custom Times For Orders.
For outpatients and discharge, variable dosing can only be written on free text medications—that is, when you choose “none of the above” from the medication search results.
