Pharmacy Technicians cannot write prescriptions. Only licensed providers such as physicians, nurse-practitioners, and physician assistants can write prescriptions. These medical professionals have what is called prescriptive authority, which is granted to them based on their years of training in treating patients and writing prescriptions.
While pharmacy technicians do not write prescriptions, they are involved in the steps of processing and dispensing them. This includes data input for new prescriptions, processing refill prescriptions, filling prescriptions, and selling prescriptions to patients after they have been checked by a pharmacist.
