An expired epinephrine auto-injector might not stop anaphylaxis. And a degraded insulin could send your blood sugar into dangerous territory. expired medication risks, the potential health consequences of using drugs past their effective date aren’t about toxicity—they’re about trust. You’re betting your health on chemistry that’s slowly breaking down.

If your medicine smells strange, looks discolored, or has changed texture, toss it.
