OK, first I will say that I am not 100% sure on this topic, so probably shouldn't be posting. That said, I can tell you what I know. I searched this topic quite a bit before filing, and I found it difficult to find the appropriate information. Because I'm doing my own taxes, I don't have the "professional opinion" but I can read IRS forms like anyone else.
So, there are two areas of interest that are somewhat related. First, the Education credits (Hope credit and a Lifelong Learning credit). These are for the most part only relevant to actual education expenses paid to qualifying universities/colleges. So, I don't think you could deduct on this basis. However, another issue relates to expenses incurred when searching for jobs...
If you are actively seeking a job WITHIN YOUR PROFESSION then you can deduct a significant portion of these expenses, such as INTERVIEW EXPENSES (this includes the cost to travel to the interview, including hotel rooms, rental cars, taxis, etc). You may also deduct expenses such as that of preparing information for your job search, such as expenses relating to the preparation of resumes (in this case, I assume an equivalent to the AMCAS application, secondary apps, etc.) and other correspondence. If you are feeling really liberal (or lucky), then you could claim that the fees spent on your MCAT, and the review course, were also dedicated toward your pursuit of this job.
OK, so the question remains...is this within our "profession"??? I would feel somewhat confident in saying that non-traditional applicants coming from a completely unrelated industry/occupation would not be eligible. However, many of us are students, both graduate and undergraduate, so we are not really changing professions are we? but then again, last time i checked, students weren't professionals, but the IRS is not attempting to distinguish between professions, occupations, etc.
So, if you ask me, BASED ON THE INFORMATION I HAVE FOUND, I believe these expenses are tax deductible. What I do not know, is to what extent they are deductible. This is often more important than the question of whether or not they are deductible, so this is the first question you should consider. The original poster said s/he was itemizing deductions, so the only other thing to consider is whether or not there is a deduction limit that says it must be above a certain percentage of your AGI (adjusted gross income), often 2%.
So, my answer is that I don't know, but I am leaning toward it being deductible. If I did not learn any more on the subject, I would take the risk (and I have spent more than the standard deduction on application and interview expenses!) Sorry so long, but at least anyone who reads this may know more than they did when they started.
Be careful not to take someone's advice on tax issues just because they are a CPA. Hopefully, someone could ask their tax accountant buddies.
