Medical Terms and
Definitions used in Pharmacy
Pharmacy technicians and other healthcare workers communicate with lots of medical terminology. So, part of your training should include learning the basics of medical terms and their definitions. Better yet, knowing pharmacy's most common terms and their definitions will supply an advantage when taking the pharmacy tech exam, during an interview or even an employer qualification test.
