Call a vet now

Call your vet or the nearest emergency vet right now. Asthma inhalers can be toxic to cats, and collapse and death are listed signs.

What to do right now

  1. Call your vet or the nearest emergency vet.
  2. Note what was eaten, how much and when.
  3. Bring the inhaler packaging.
  4. Keep your cat calm.
  5. Remove what is left.

Don't

  • Do not make your cat vomit unless a vet tells you to.
  • Do not give any human medicine.

Why it can be dangerous

Asthma inhalers often contain beta-agonist drugs that expand the lungs.[1] Asthma inhalers may also contain steroids that decrease inflammation in the lungs.[1]

Signs to watch for

  • Collapse
  • Death

Where it is found

  • Human medicine
  • Veterinary medicine
If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
