Can I take expired medication?
Last updated September 3, 2026.
The FDA advises against taking expired medication: past the expiration date, potency and safety are no longer guaranteed, and for critical drugs that uncertainty is a real risk. The date marks the limit of the manufacturer's certification under proper storage; beyond it, drugs can lose potency and degrade unpredictably. Stakes scale with the drug: a faded painkiller is an annoyance, but weakened antibiotics can fail infections and drive resistance, and sub-potent heart, seizure, insulin, epinephrine, or nitroglycerin products can be dangerous precisely because the condition they treat is not forgiving. Storage is part of the story: heat and humidity speed breakdown, so bathroom cabinets are the wrong home for medication. The shelf-life extension data you may have heard about comes from controlled government stockpile testing, not a general pass for home cabinets. The working rules: replace critical items before they lapse (epinephrine auto-injectors, rescue inhalers), never self-treat a new infection with expired antibiotics, follow "discard after" pharmacy labels, and use take-back programs for disposal instead of the toilet.
What to do
- Default rule: expired means replace, per FDA guidance.
- Critical drugs, zero slack: epinephrine, insulin, nitroglycerin, seizure and heart meds.
- Never expired antibiotics: under-dosing fails the infection and breeds resistance.
- Store cool and dry: not the bathroom cabinet.
- Dispose via take-back: pharmacy programs, not flushing.
