25 OTC medications Tips for Health Savings Accounts (2026)

HSA eligible expense lists can change, especially with new legislation. Always check the current IRS Publication 502 for the most up-to-date list of qualified medical expenses.

For every OTC purchase made with HSA funds, retain an itemized receipt showing the product name, date, and cost. This is your primary defense in an IRS audit.

Using your HSA debit card for all eligible OTC purchases creates an automatic audit trail, simplifying expense tracking and reducing manual record-keeping errors.

While most OTCs no longer require a prescription, some specific items, particularly certain medical devices or supplements, might still need a Letter of Medical Necessity.

Only OTC products used for the diagnosis, cure, mitigation, treatment, or prevention of disease are eligible. Cosmetic items are not.

Many HSA providers offer their own searchable databases of eligible expenses, which can be a quick reference point, though the IRS Pub 502 is the definitive source.

If you pay for OTCs with personal funds, batch your reimbursement requests to your HSA to reduce transaction fees and administrative effort.

For frequently used OTCs like pain relievers or allergy medication, purchasing in larger quantities can be more cost-effective over time.

Generic OTC medications often contain the same active ingredients as brand-name versions but at a lower cost, stretching your HSA dollars further.

If family members use your HSA for their OTCs, ensure they understand what's eligible and the importance of keeping receipts.

Sunscreen with an SPF of 15 or higher is generally HSA-eligible because it prevents skin cancer and damage.

Certain OTC items for dental and vision care, such as eye drops, contact lens solution, and denture adhesives, are HSA-eligible.

Common first aid items like bandages, antiseptic wipes, and gauze are HSA-eligible as they treat or prevent injury.

Regularly reviewing your HSA spending on OTCs helps you budget effectively for future healthcare needs and identify spending patterns.

Many basic medical devices sold over-the-counter, like thermometers, blood pressure monitors, and glucose meters, are HSA-eligible.

Use year-end HSA checklists provided by financial advisors or benefits managers to ensure you've maximized your contributions and spent down any necessary funds (for FSAs, but good practice for HSAs too).

While not common, some countries may have different definitions of OTC or require prescriptions for items that are OTC in the US. Plan accordingly.

While rare for small OTC purchases, large or frequent unsubstantiated claims could flag an audit. Proper record-keeping mitigates this risk.

If you have unique medical needs or questions about specific, less common OTC items, a tax professional specializing in healthcare can provide clarity.

Before purchasing, use online tools or apps to compare prices of eligible OTC medications across different pharmacies to get the best value.

It's generally cleaner and easier for record-keeping to use one payment method per transaction. If an item is partially eligible, buy it separately.

Healthcare legislation, like the CARES Act, can significantly impact HSA eligibility for OTCs. Subscribe to updates from your HSA provider or financial news sources.

Periodically compare your personal OTC expense records with your HSA account statements to catch any discrepancies or missing reimbursements.

Anticipate common seasonal illnesses or chronic conditions and stock up on eligible OTCs strategically throughout the year, especially during sales.

For items that have both a medical and a general-use purpose (e.g., certain hand sanitizers or moisturizers), ensure the medical intent is clear. Many require an SPF rating or active medicinal ingredient to qualify.
