It seems very clear that the only non-prescription med you can deduct is insulin.
A side note for further illustration. I have a med that is prescribed for me and I pick it up under my health insurance, with a small copay. Oddly, I can also walk into a certain big box store and just grab one and pay for it on my own. I'm not sure which way is cheaper, though I think my insurance is not actually paying anything when I get it under my prescription. So, when I pay for it in the store, not deductible. In the pharmacy, assuming I meet the floor, and I have enough in general to itemize, I can deduct it.
It's a royal PITA to have a medical condition that requires meds that may be expensive but not deductible. Makes little sense, IMHO. But I didn't write this insane tax code.
Oddly, one of my kids is T1D, and uses insulin. We can't get it without a prescription. But if we could, what we pay would be deductible.
