There are many scopes of the workplace for the Certified Pharmacy Technician. In a retail setting, a CPhT works under the direct supervision of a pharmacist who dispenses prescription medication (tablets, capsules, gels, ointment, creams, suspensions, injections, and inhalation medications), and must be familiar with over-the-counter areas as well as third party insurance billing processes. In an inpatient setting, the CPhT works throughout the hospital, packing and dispensing medications in satellite pharmacies and to the various nursing units; compounding intravenous medication while using aseptic technique; narcotic medication dispensing and inventorial procedures; as well as documenting patients' weight, height, drug allergies and other needed information in medication records.
