Everyday OTC
Is anti-diarrheal, laxatives & gas relief FSA eligible?
FSA & HSA eligible
Yes — OTC digestive remedies like Imodium, Miralax, and Gas-X are FSA and HSA eligible.
Anti-diarrheals, laxatives, stool softeners, gas relief, and upset-stomach standbys like bismuth (Pepto-Bismol) all qualify as OTC drugs. A travel-season restock is a painless way to absorb a small remaining balance.
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.
