The correct answer is option A, that is, only when authorized by a supervising pharmacist.
Pharmacy technicians function under the direct supervision of a licensed pharmacist and do various pharmacy-associated activities. They refer any queries considering drug information, reading prescriptions, or health issues to a pharmacist.
They work in a broad field of practice settings, like hospitals, community pharmacies, in home health care settings, in the military, educational programs, long-term care facilities, and managed health care organizations.
