Do not rely on an expired inhaler: past expiry the dose per puff is unreliable, and even before expiry, sprays beyond the labeled dose count may deliver too little medicine.
In a true breathing emergency with nothing else in reach, use it while calling emergency help - some albuterol usually beats none - then replace it. Prevention: check the expiry date and dose counter monthly, carry an unexpired spare, and know the dry-powder clock: some expire 13 months after the foil wrapper opens, whatever the printed date says. An inhaler that keeps expiring unused means good control - but never carrying it is luck, not control. Pymander is a free AI doctor, 24/7 by text, and can help you set a replacement routine.
What to do
Common questions
Can you use an expired inhaler?
The FDA's general rule for expired medicines applies hard here: do not use them - not because albuterol turns poisonous, but because you cannot trust the dose. An inhaler's promise is a precise puff; past the expiration date the propellant and medication degrade, and MedlinePlus adds a related trap: even before expiry, sprays beyond the labeled dose count (60 or 200 puffs) may deliver too little medicine. For most expired medicines that means reduced effect - annoying. For a rescue inhaler during an asthma attack, an underpowered puff is a different class of problem. So the honest hierarchy: a true breathing emergency with only an expired inhaler in reach - use it while calling emergency help, because some albuterol usually beats none; then replace it. The maintenance that prevents the dilemma: check the expiry date and the dose counter monthly, carry an unexpired spare, and remember the powder-inhaler clock: some dry-powder versions expire 13 months after the foil wrapper is opened, whatever the printed date says. If your inhaler keeps reaching expiry unused, tell your doctor - needing it rarely is good control, but never carrying it is luck, not control.
