Is prescription medications FSA eligible?
Yes — prescription drug co-pays and out-of-pocket prescription costs are FSA and HSA eligible.
Prescriptions are the canonical qualified expense: co-pays, the full cash price when you skip insurance, and insulin (which qualifies even over the counter). If a December refill is coming anyway, filling it before the deadline is the easiest spend-down there is.
How to pay for it
- Tap your FSA/HSA debit card at checkout — most pharmacies, optical shops, and many online retailers take it directly.
- Buying online? FSA-only stores pre-filter their catalog to qualified items, so nothing in your cart bounces at checkout.
- No card on hand? Pay out of pocket and file a claim with your administrator — just keep the itemized receipt (a photo is fine).
Does the same answer apply to an HSA?
Yes. FSAs and HSAs share the same qualified-medical-expense rules (IRS Publication 502), so eligibility is identical. The difference is the deadline: FSA money is forfeited at the end of the plan year, while HSA money never expires.
