When you reach for your expired inhaler, a handheld device that delivers medication directly to the lungs for asthma or COPD. Also known as a puffer, it’s meant to be your quick fix during a breathing emergency. But if it’s been sitting in a drawer for two years, does it still work? The answer isn’t simple. Most manufacturers list an expiration date for legal reasons, but studies show many inhalers retain most of their potency for at least a year past that date—if stored properly. Still, that doesn’t mean you should rely on it.
What changes over time? The propellant can weaken, the valve can clog, and the medication may settle or break down. A 2018 study from the Journal of Allergy and Clinical Immunology tested albuterol inhalers up to 12 months past expiration and found 85% still delivered at least 90% of the labeled dose. But that’s under ideal conditions: cool, dry, away from sunlight. If your inhaler was left in a hot car, in a bathroom with steam, or dropped on the floor, it’s not just old—it’s unreliable. And when you’re gasping for air, you don’t want to guess.
That’s why asthma medication, drugs like albuterol or salmeterol that open airways during flare-ups and COPD inhalers, long-term controllers like fluticasone or tiotropium that reduce inflammation and mucus need to be treated like life-saving tools, not spare parts. If your inhaler is expired, and you’re out of refills, don’t risk it. Call your doctor. Ask if you can get a sample. Check local clinics or pharmacies that offer low-cost programs. Some insurance plans let you get early refills if you’re running low. And if you’re using a spacer, make sure it’s clean—grime can block what little dose is left.
There’s a reason your pharmacist asks if you’re still using that old inhaler. It’s not just about rules—it’s about safety. A failed rescue inhaler during an attack can mean a trip to the ER, or worse. You wouldn’t drive with bald tires or a dead battery. Don’t treat your lungs any differently.
