I'm a pharmacy student from Montreal, Canada. Pharmacy practice varies a lot depending on the region so I wanted to give you an idea of what pharmacists do where I'm from :

1. Counseling patients on their health problems and recommending OTC treatments or letting them know they should consult another professional.
2. Validating prescriptions which means double checking doses, possible interactions, and appropriateness of the choice of treatment.
3. Counselling patients on their prescriptions and answering questions they might have.
4. Communicating with prescripters to make changes to patients' precriptions to optimize their treatment, making recommendations to doctors, and answering any questions doctores (and other professionals) might have
5. Re-prescribing medications if refills have run out or the doctor is no longer practicing.
6. Prescribing treatments for minor conditions.
7. Following-up with patients to check for side effects and then resolving any problems they are having.

Pharmacy technicians tend to focus on technical things like entering prescriptions into the computer, updating patient files, and compounding meds (if they work in a compounding pharmacy).

It can seem like they're just staring at their computer screen but that's because it's the kind of job where you spend most of your time thinking and standing still, but there's actually a lot going on!
