Using FSA & HSA for prescription medications

FSAs and HSAs can pay for prescription drugs with pre-tax dollars, including GLP-1s like Wegovy, Zepbound, and Ozempic. This page covers eligibility rules, documentation requirements, and how to submit claims.

What's eligible

  • Prescription medications — GLP-1s, ED drugs, hair-loss medications, prescription skincare — are eligible if your physician issued a valid US prescription.
  • Telehealth consultations — the consult fee from Ro, Hims, Henry Meds, and similar providers is generally eligible when the consultation results in or relates to a prescription.
  • Lab work required before or during a prescription cycle (e.g., A1C testing for GLP-1 monitoring) is eligible.
  • Sharps containers for injectable disposal are eligible.

What's NOT eligible

  • Compounded medications without a valid prescription — even if dispensed through a telehealth program. Some FSA/HSA administrators are stricter than the IRS minimum; ask your administrator before paying.
  • Subscription / membership fees not tied to a specific Rx (general telehealth memberships often fall here). Pricing structures matter — bundle pricing may be partially eligible.
  • Cosmetic-only Rx (e.g., tretinoin prescribed solely for cosmetic concerns) — generally not eligible. Acne or photoaging treatment is.
  • Over-the-counter vitamins, supplements, or general wellness products.

How to pay & document

  1. Pay with your FSA/HSA debit card at the pharmacy or telehealth checkout. Keep the receipt + the pharmacy label showing the Rx number.
  2. If paying out-of-pocket and reimbursing later, save the pharmacy receipt + the prescription info. Most administrators accept the standard pharmacy receipt; some require an itemized claim form.
  3. For telehealth consult fees, save the provider's invoice showing the visit was for a specific medical evaluation. A generic "subscription" line-item is harder to justify.
  4. If your administrator denies a claim, you can usually appeal with a letter of medical necessity from your prescriber.

Tax savings on a $1,350/month GLP-1

If you pay $1,350/month for a GLP-1 and use FSA/HSA dollars taxed at a 30% marginal rate, you save roughly $405/month or $4,860/year in taxes. The medication still costs the same, but you pay with pre-tax money.

Illustrative only. Actual tax savings depend on your marginal rate and your FSA/HSA balance.
