If your rescue inhaler suddenly stopped working, you may be dealing with one of several issues ranging from a major product recall to a mechanical failure in the canister itself. In May 2025, AstraZeneca voluntarily recalled over one million Airsupra inhalers due to a defective delivery system that could cause the device to fail mid-use. Separately, GlaxoSmithKline recalled batches of Ventolin HFA inhalers because some canisters lacked sufficient propellant to deliver their full labeled doses. If you rely on either of these products, the problem may not be your lungs or your technique — it may be the inhaler itself.
Beyond recalls, there are medical and practical reasons a rescue inhaler can lose its effectiveness over time. Frequent use of albuterol can lead to a tolerance effect where the body becomes less responsive to the medication. Improper inhaler technique, which is far more common than most people realize, can mean the drug never reaches the airways properly. For older adults and those living with cognitive decline, these factors compound quickly — forgetting whether a dose was taken, struggling with the coordination required to actuate and inhale simultaneously, or failing to notice that a canister has expired. This article covers the recent recalls in detail, the medical reasons your inhaler may have stopped helping, and practical steps to take right now.

Why Did My Rescue Inhaler Suddenly Stop Working?
The most immediate answer for many patients in 2025 is a product defect. AstraZeneca’s recall of 1,043,535 Airsupra canisters — a combination inhaler containing albuterol and budesonide — was triggered by a defective delivery system that could cause the inhaler to fail during use. The FDA classified this as a Class II recall, meaning use of the affected product could cause temporary or medically reversible adverse health effects. The affected lots have expiration dates ranging from July 31, 2025 through September 30, 2027, so even recently purchased inhalers could be compromised. If you have Airsupra at home, check the lot number on the canister and contact your pharmacy immediately if it falls within the recall window. The Ventolin HFA recall tells a slightly different story.
GlaxoSmithKline found that certain canisters may not contain enough propellant to deliver the full 200 actuations through the end of their shelf life. In practical terms, this means an inhaler might work fine for the first hundred puffs and then gradually deliver less and less medication — a particularly dangerous scenario because the decline is subtle. One telltale sign is bulging of the outer wrapper, which indicates propellant leakage. If your Ventolin canister looks swollen or distorted compared to when you bought it, do not use it. There is also the matter of Teva’s Digihaler products, which were withdrawn from the market entirely in 2024-2025. The withdrawal happened because the companion Digihaler App and Dashboard were discontinued, rendering the smart inhaler features nonfunctional. If you were prescribed a Digihaler product and have not yet switched to an alternative, you may be using a device that is no longer supported or available for refills.
Medical Reasons Your Inhaler Is No Longer Effective
Not every inhaler failure is a hardware problem. One of the most common reasons a rescue inhaler stops providing relief is improper technique, and this is especially relevant for older adults and people with cognitive impairment. The coordination required — exhaling fully, pressing the canister, inhaling slowly and deeply, then holding your breath — is a multi-step motor sequence that deteriorates with conditions like dementia, Parkinson’s disease, or even arthritis in the hands. Jefferson Health recommends bringing your inhaler to every medical appointment so your doctor or respiratory therapist can watch you use it and correct any issues. Many patients who think their medication has stopped working discover that a simple adjustment in timing or posture restores its effectiveness. However, if your technique is fine and you have been using albuterol multiple times a day for weeks or months, beta-agonist tolerance may be the culprit.
The beta-2 receptors in your airways can become desensitized with frequent stimulation, meaning the same dose of albuterol produces a weaker bronchodilating effect over time. This is not the same as the drug “wearing off” — it is a physiological adaptation. Your doctor may need to adjust your controller medication, add a long-acting bronchodilator, or explore whether your underlying condition has worsened and requires a different treatment strategy altogether. There is one scenario that catches many patients off guard: misdiagnosis. Conditions like vocal cord dysfunction can closely mimic asthma symptoms — wheezing, shortness of breath, chest tightness — but they do not respond to albuterol at all. If you have been treated for asthma and your rescue inhaler has never worked particularly well, it is worth asking your physician about alternative diagnoses. This is especially important for patients who were diagnosed years ago without spirometry or other confirmatory testing.
The Albuterol Shortage and What It Means for Your Prescription
Liquid albuterol used in nebulizers has been on the FDA’s medication shortage list since October 2022, and the situation worsened significantly in February 2023 when Akorn Pharmaceuticals shut down three manufacturing plants and ceased all U.S. operations. Akorn had been a major supplier of generic nebulizer solutions, and its exit from the market left a gap that other manufacturers have been slow to fill. As of mid-2025, the shortage is improving but not fully resolved. Here is the critical distinction that many news reports gloss over: the shortage primarily affects liquid albuterol for nebulizers, not the metered-dose rescue inhalers that most people carry in a pocket or purse.
If your pharmacy has told you they cannot fill your albuterol prescription, ask specifically whether they mean the nebulizer solution or the MDI. For patients who use a nebulizer at home — which includes many older adults with COPD or severe asthma who lack the hand strength or coordination for an MDI — the shortage has been a genuine crisis. Some have had to switch pharmacies, try mail-order options, or transition to an inhaler with a spacer device. If you or a family member with dementia relies on nebulizer treatments, the shortage adds another layer of complexity to an already challenging medication routine. Talk with your prescriber about whether an MDI with a valved holding chamber (spacer) could serve as a bridge. Spacers reduce the coordination demands significantly and can make an MDI viable for patients who otherwise cannot use one effectively.
What to Do Right Now If Your Inhaler Fails
Start by checking the physical canister. Look at the expiration date printed on the device or its packaging. Examine the outer wrapper for any bulging or distortion, which could indicate propellant leakage. Shake the canister — if it feels unusually light or you hear no liquid moving inside, it may be empty or compromised. Then check the lot number against the current recall lists for both Airsupra and Ventolin HFA. The Asthma and Allergy Foundation of America maintains updated recall alerts on its community blog, and your pharmacist can verify whether your specific lot is affected. If the canister checks out physically, the next step is an honest assessment of your technique. Spray the inhaler into open air and watch the mist — it should produce a fine, even spray.
If the output looks weak or uneven, the actuator may be clogged. Most inhalers can be cleaned by removing the canister, running warm water through the plastic housing, and allowing it to air dry completely before reassembling. This is a simple fix that resolves a surprising number of “my inhaler stopped working” complaints. However, if cleaning does not help and the canister is not expired or recalled, do not simply increase your dose. Contact your prescriber. Needing your rescue inhaler more than twice a week is itself a signal that your asthma is not well controlled and your treatment plan may need to change. For caregivers of someone with dementia, consider keeping a written log — posted near the inhaler — of the date each new canister is started, the expiration date, and a running count of puffs used. Most rescue inhalers contain 200 doses. Without tracking, it is easy to keep using an empty canister for days or weeks without realizing it, especially if the person using it cannot reliably report whether they feel relief.
Expired Inhalers and the Risks of Keeping Old Canisters Around
An expired inhaler is not necessarily dangerous, but it may be ineffective, and that is its own kind of danger during an asthma attack. The active medication degrades over time, and the propellant that drives the drug into your lungs can leak slowly through the canister seal. The result is an inhaler that seems to fire but delivers a fraction of the intended dose — or none at all. This is particularly insidious because the actuator still clicks, you still taste something, and you assume the medication is working when it is not. The risk multiplies in households where medication management is inconsistent.
It is not uncommon for caregivers to find three or four half-used inhalers scattered around a home, none of them current. For someone with dementia, the instinct to reach for the nearest inhaler during a breathing crisis can mean grabbing a canister that expired two years ago. A practical safeguard is to dispose of expired inhalers immediately — do not leave them “just in case.” Replace them with a current prescription and store the active inhaler in one consistent, visible location. Some caregivers attach the inhaler to a lanyard or keep it in a clearly labeled pouch alongside other daily medications. One additional warning: do not stockpile inhalers in anticipation of shortages or price increases. Albuterol MDIs have a finite shelf life, and hoarding creates the very scenario described above — a collection of aging canisters with uncertain potency.
Inhaler Costs Are Changing — What You Should Know
Affordability has long been a barrier to consistent inhaler use, and that landscape is shifting. GSK capped the monthly out-of-pocket cost for Ventolin HFA at $35 starting in January 2025, a meaningful reduction for patients who previously faced retail prices averaging around $98, with some uninsured patients paying $200 to $600 per month. However, this cap does not apply to Medicare or Medicaid patients due to federal pricing rules, which means many older adults on fixed incomes are excluded from the savings.
Illinois has gone further, passing legislation that caps inhaler costs at $25 per month effective January 2026. If similar bills advance in other states, the financial pressure that leads some patients to ration puffs or skip refills may ease. Rationing rescue medication is one of the most common and most dangerous cost-driven behaviors — and for patients with cognitive impairment who cannot articulate that they are short of breath, a caregiver’s assumption that “we still have an inhaler somewhere” is not a substitute for a current, filled prescription.
Looking Ahead — Better Monitoring and Safer Options
The withdrawal of Teva’s Digihaler line — a product designed to track inhaler usage digitally — is a setback for remote monitoring, but the underlying concept remains sound. For dementia caregivers, any tool that confirms whether a dose was actually taken and properly delivered would be invaluable. Several companies are developing smart inhaler attachments that log actuations and send alerts to a caregiver’s phone.
These are not yet standard, but they represent a promising direction for a population that cannot always self-report symptoms or medication use. In the meantime, the most reliable safeguard is a structured routine: one current, non-recalled inhaler stored in a consistent place, a spacer device to reduce technique errors, a caregiver who periodically observes the patient using the device, and a prescriber who reviews the asthma or COPD action plan at least annually. Rescue inhalers are designed to be reliable in a crisis. When they are not, the fix is almost always identifiable — and usually straightforward.
Conclusion
A rescue inhaler that suddenly stops working is not something to shrug off or troubleshoot alone. The 2025 recalls of Airsupra and Ventolin HFA affected well over a million canisters, and the ongoing liquid albuterol shortage has left some nebulizer-dependent patients scrambling for alternatives. At the same time, medical factors like beta-agonist tolerance, worsening disease, technique problems, and even misdiagnosis can all mimic a device failure. Identifying the actual cause matters because the response is different in each case. If you are a caregiver for someone with dementia or another cognitive condition, take an active role in inhaler management.
Check the lot numbers against current recalls. Verify expiration dates. Watch the person use the device and note whether the technique looks effective. Replace old canisters promptly and do not assume that a half-used inhaler from last year is still viable. Talk to the prescribing physician if rescue inhaler use has increased — that pattern itself is a clinical signal that the treatment plan needs adjustment.
Frequently Asked Questions
How do I check if my inhaler is part of the 2025 Airsupra recall?
Look at the lot number and expiration date printed on the canister. The recall covers lots with expiration dates from July 31, 2025 through September 30, 2027. You can verify through your pharmacist or the Asthma and Allergy Foundation of America’s recall alert page. Do not use an affected inhaler — contact your pharmacy for a replacement.
Does the albuterol shortage affect my rescue inhaler?
Probably not. The shortage that has persisted since October 2022 primarily affects liquid albuterol used in nebulizers, not metered-dose inhalers. MDI rescue inhalers remain generally available, though specific brands or generics may occasionally be out of stock at individual pharmacies.
Can using my rescue inhaler too often make it stop working?
Yes. Frequent use of albuterol can cause beta-agonist tolerance, where the beta-2 receptors in your airways become less responsive to the medication over time. If you are using your rescue inhaler more than twice a week, your underlying condition may not be well controlled and you should discuss your treatment plan with your doctor.
What should I do if my inhaler seems to fire but I do not feel relief?
First, check the expiration date and look for signs of propellant leakage such as bulging packaging. Try cleaning the actuator by removing the canister and rinsing the plastic housing with warm water. If the device still seems ineffective, bring it to your next medical appointment so your provider can evaluate both the device and your technique.
Is there a way to make inhalers easier for someone with dementia to use?
A valved holding chamber, commonly called a spacer, significantly reduces the coordination required. The patient does not need to time their inhalation precisely with the actuation. Some caregivers also find it helpful to store the inhaler in a single visible location with a written reminder card and to track doses in a simple log.
Will the $35 cap on Ventolin HFA help Medicare patients?
Unfortunately, no. GSK’s $35 monthly cap, which took effect in January 2025, does not apply to Medicare or Medicaid patients due to federal pricing regulations. Illinois has passed a $25 per month cap effective January 2026, but state-level caps vary and may also have eligibility limitations.
