Your best bet is to apply those out of pocket expenses in one of two ways.
Open up a Flexable Spending Account. This is beneficial because whatever amount you open it for brings your taxable income level down (if you make 20,000 a year & open an account for 5,000 then your taxable income is already reduced to 15,000). The $$ is already there to be spent for co pays, over the counter meds, xrays etc. The bad thing about this (especially when starting out) is if you dont use the total amount you opened with then you lose it. IF you go over that amount I am not sure what happens.....
You could use the medical as a deduction, but you can only deduct what is OVER 7.5% of your income so if you dish out costs that arent over that then you are just paying it out & havent met the requirements to get a break on the income tax return.
Here is a link regarding all this that might help a bit more. I think many americans are falling into this gray area. Make too much for assistant, but not enough to really handle it on their own.
