Pharmacy Guide: A Prescription Drug Glossary

pharmacy_history

Pharmacists have a unique position. They need to work with doctors in filling the orders for drugs that are given. Pharmacists also need to communicate with the patients who receive prescription drugs. They need to be able to explain what the drugs do and any possible side affects. Finally, Pharmacists also work with insurance companies and help to determine what the insurance coverage is for the prescription.

Because of these various interactions, Pharmacists have a vocabulary that is unique to their profession. Here are a few of the commonly used terms and definitions that are used by Pharmacists when talking about prescription drugs:
