as far as i know, it depends if you itemize your deductions or not. (basically, they could be, but only if these expnses are bigger than the standard deductions (around $3,000 for a single person?)
Medical expenses must exceed 7.5% of your adjusted gross income to figure into your itemized deductions on Schedule A. For example, if you make $50K then your medical expenses would need to be in excess of $3,750, and only the excess would be deductible. Also, it is not a direct credit so the amount you deduct is taken from adjusted gross income, not your tax bill.
This is my personal understanding of the process.
