Is Cold Medicine FSA Eligible? Yes. The Full Cold and Flu List

The CARES Act became law on March 27, 2020. Section 3702 dropped the prescription requirement for over-the-counter medicine in HSAs and FSAs. The cough syrup, decongestant, and fever reducer in your cart qualify without a doctor's note.

This is not a new rule. For HSAs, it covers amounts paid after December 31, 2019. For health FSAs, it covers expenses incurred after December 31, 2019.

Here is the seasonal list. What qualifies, what does not, and what the pharmacy receipt has to show.

The Short Answer

Why Publication 502 Seems to Say No

Search IRS Publication 502 and you will find this line in the 2025 edition.

"Except for insulin, you can't include in medical expenses amounts you pay for a drug that isn't prescribed."

That sentence is accurate for what Pub 502 covers. Pub 502 explains the itemized medical deduction on Schedule A. HSAs run on a different section of the tax code.

The IRS instructions for Form 8889 spell out the gap. Except for insulin, nonprescription medicines do not qualify for the Schedule A deduction. But the instructions say they "do qualify as expenses for HSA purposes."

The statute shows the change. Before 2020, the HSA code section allowed medicine only if it was "a prescribed drug" or insulin. The CARES Act removed that sentence. A June 17, 2020 IRS release said it plainly: "over-the-counter products and medications are now reimbursable without a prescription."

So OTC cold medicine cannot go on Schedule A. It can come out of your HSA tax-free.

The Label Test

One check sorts the cold aisle fast. Turn the box over.

The FDA requires a standard Drug Facts label on all over-the-counter drug products. Dietary supplements do not get that label. The FDA regulates them as food, with a Supplement Facts panel instead.

• ●Drug Facts label: an OTC medicine. Eligible without a prescription.
• ●Supplement Facts panel: a supplement. The Pub 502 supplement rule applies.

Products in the same aisle can carry different panels. Read the back of the box, not the shelf tag. The label is a shortcut, not an IRS rule. Your plan administrator has the final say on edge cases.

The Cold and Flu List

The rows above cover categories, not brands. A specific product can still fail the label test.

Thermometers

Pub 502 has no thermometer entry. It does have a Diagnostic Devices entry. "You can include in medical expenses the cost of devices used in diagnosing and treating illness and disease."

A thermometer is how a fever gets diagnosed at home. Lively, an HSA provider, lists thermometers as eligible for HSAs and FSAs. Details are on Are Thermometers HSA-Eligible?.

COVID-19 Tests and Masks

The 2025 Form 8889 instructions cover home tests directly. Home COVID-19 testing for you, your spouse, or your dependents qualifies. The instructions call the cost "an eligible medical expense for tax purposes." It "may be paid or reimbursed from an HSA."

Masks, hand sanitizer, and sanitizing wipes have a purpose test. They count when the primary purpose is preventing the spread of COVID-19. A bulk pack of hand sanitizer for the office supply closet is a different purchase.

Flu Shots

Pub 502 defines medical expenses as costs of "diagnosis, cure, mitigation, treatment, or prevention of disease." A flu shot is prevention. Lively lists flu shots as eligible for HSAs and FSAs.

One catch. HSA money only covers amounts "not compensated for by insurance or otherwise." A $0 shot leaves nothing to reimburse.

When you would actually pay is covered in Is a Flu Shot HSA Eligible? Yes. Here Is When You Would Actually Pay.

Vitamin C, Zinc, and Elderberry

This is where the cold aisle splits. Pub 502 excludes "nutritional supplements, vitamins, herbal supplements" as a group. Its reason: "These items are taken to maintain your ordinary good health and aren't for medical care."

The exception needs a medical practitioner's recommendation "as treatment for a specific medical condition diagnosed by a physician." A box of vitamin C bought because everyone at work is sick does not meet that bar.

Lively says vitamins may be eligible with a letter of medical necessity. Without one, they are not. The full breakdown is in Are Vitamins and Supplements HSA Eligible? What Actually Qualifies.

Humidifiers Need a Letter

Pub 502 has no humidifier entry. Lively says humidifiers "are eligible for reimbursement with a Letter of Medical Necessity (LMN)." Without the letter, treat a humidifier as not eligible.

How to get one is in Letter of Medical Necessity (LMN): What It Is and How to Get One. Keep the letter with the receipt.

One FSA Exception

A limited-purpose FSA is a different account. Lively lists cough drops, thermometers, and flu shots as not eligible under one. The yes answers above apply to HSAs and general-purpose health FSAs.

What the Receipt Needs to Show

Publication 969 says "You must keep records sufficient to show that" your HSA money paid qualified medical expenses. The record has to name the expense.

A credit card slip shows a store, a date, and a total. It does not show what was in the bag. Say a hypothetical pharmacy charge is $38. The slip cannot prove that was cough syrup and not a candy bar.

The itemized register receipt can. It lists each item and its price.

At Walgreens, the store says your basket gets "divided into two buckets: FSA/HSA and non-FSA/HSA." You pay the first bucket with the card and the rest separately. How a receipt marks eligible lines differs by chain. These two posts walk through each one line by line:

• ●CVS HSA & FSA: Card Use, Receipts, and Past Records
• ●Walgreens HSA & FSA Eligible Items: Read Your Receipt

Swiping the HSA card at the register does not replace the receipt. The card proves payment. The receipt proves what you bought.

Snap a photo of the receipt at the counter. Tripl reads the date, amount, category, and description from it. If you have a letter for a humidifier, attach it to the same expense.
