I work in very busy pharmacy and let me say the pharmacist's as well as the techs catch many, many medication mistakes made by doctors. I would trust a pharmacists opinion about medications before most doctors. I think the doctors are so busy they just cant keep up with all the new drugs as well as the many interactions prescription and OTC drugs can cause.
I'm delighted that you have a high opinion of the people that you work with; that makes for a healthy working environment. I'm delighted also that the pharmacists are doing exactly what they are supposed to do, which is to verify and, if necessary, confirm a prescription as ordered by the MD. That's one of the many advantages of having specialists in medicine who are educated and trained on specific and sometimes comparatively narrow career tracks.
