pharmacy dispensers at work
My cousin is a qualified dispenser at the local pharmacy who knows how to handle patients with false prescriptions.
There are different types of dispensers: pharmacy dispensers, qualified and trained medical persons who know how to give on-the-counter medicine and prescription medication; optical dispensers, also sometimes called ‘opticians’, qualified and trained medical persons who know how to understand the opticians prescription and make eye-glasses for patients; hearing aid dispensers, qualified and trained medical persons who help patients with hearing problems in choosing the best suitable hearing aid depending on the ENT specialist’s prescription.
Drug dispensers are those people who have license to give harmful drugs, such as marijuana, cannabis, and some sleep causing drugs, for those people who need them only for medicinal purpose.
