Hey everyone,
I am also a PharmD studying for the MCAT currently and planning on returning to medical school. I cannot speak for others, but my major reason for going back is "lack of fulfillment" with pharmacy. I am actually in the middle of a pharmacy residency right now in a hospital doing lots of "clinical pharmacy" things, however, it is not enough for me. My guess is that most pharmacists who are returning to medical school have similar feelings as I do.
There is a degree of disillusionment that goes on in pharmacy school. I heard many stories in my pharmacy classes about clincal pharmacists being the "leaders" on the medical team and physicians being clueless about drug therapy. What I have found is that in practice that is very much not the case. Medical interns and residents and to some degree hospitalists or internal medicine physicians often are clueless about a lot of drug therapies, however, specialists are not. Cardiologists are far more knowledgeable about cardiovascular drugs than I am, eventhough I am the "drug expert" because that is their job. The fact of the matter is that despite what you are told in pharmacy school..the role of the clinical pharmacist is still fairly limited, and that may be okay for many.
For me, I have found myself wanting to do more than just manage a patient's medications or make a couple interventions or recommendations on drug therapy here or there. Throughout the course of this year I have become extremely interested in the diagnosis and inital patient work-up and care plan, things that pharmacy cannot and will not ever offer me.
The key is to understand that the role of the pharmacist is to only manage drug therapy (and sometimes it is a limited role at that). If that is what interests you most then pharmacy is an awesome career with a great salary and flexible hours and I say go for it. I think that pharmacy professors and pharmacy school that try to sell clinical pharmacy as the leader of a medical team or as a profession that is making loads of medication interventions daily are doing a disservice to the profession and to the students.
I wish all the pharmacists who are deciding to go back, like myself, good luck in their quest. Don't let people try to tell you are foolish for going further in debt and giving up 100K+ jobs. The important thing is that you end up with a career that is meaningful and fulfilling to you.
