Different pharmacists let you do different things. Some let me work on patient cases and call prescribers. Others just want me to do tech things. Others regularly quiz me and some straight up pimp me, which is fine really. I don't mind getting pimped. I wish they'd do it more often.
I can go on rounds if I want or go to codes with the pharmacist. But, if I do that, some of the other techs can get upset so I don't do it often. I went to a code a while back and got saline pushes ready, took out some drips and got them ready, had epi ready. It was kind of cool and then the physician did a sternal rub. Everything happened so fast. The sternal rub kind of freaked me out though. Especially since I'd gotten to know that patient and they'd been around awhile.
I say do as much as they'll let you. Learn IVs, become familiar with dosing and diluents, ask questions, offer to help, offer to pull literature for the pharmacists when they're busy, ask them to let you look over their shoulder when doing consults or dosing/kinetics.
Take it all in my friend. Learn everything the techs do and learn Pyxis. You'll have to know it as a pharmacist (like how to recover drawers- spatulas are your friends- , or load/unload, inventory, etc.) Because the nurses will call and say the med is grey in Pyxis but they looked under brand name or the drawer has failed.
Learn the workflow as much as possible. Every person is essential for making things run smoothly. I think it's great to know the positions.
Learn the meds on the formulary, the process for "patient's own med", what narcs you have, what's on backorder/mfg out, how to compound, etc. There is so much to learn.
Sometimes we'd get students who thought they were "above" doing tech work. But without techs, everything would come to a halt. So, be nice to them. They'll show you the ropes.
Also, remember that every place is different.
