Gave a little pink Benadryl tablet to my cat and now they're foaming at the mouth—did I do something wrong, should I be calling Dial A Vet?

Answer

It sounds like your cat may be having a reaction to the Benadryl. Foaming at the mouth can be alarming and might indicate a serious issue.

  • Foaming at the mouth can be a sign of a reaction to medication.
  • Noticing any unusual behavior is important after giving new medication.
  • Immediate care might be necessary if symptoms are concerning.

Benadryl (diphenhydramine) is sometimes used in cats for allergies, but it is crucial to ensure the dosage is correct as cats are small animals and can be sensitive to medications. Foaming at the mouth could mean your cat is having trouble with the medicine or possibly another substance that may have been ingested. This reaction is not typical and can be a sign of distress. Make sure to monitor your cat closely, and if these symptoms persist or worsen, it’s important to get him examined by a vet without delay.

If this is an emergency, please seek immediate veterinary care.

    If you notice signs such as foaming at the mouth, unusual lethargy, or any other concerning symptoms after administering a medication, contact a vet immediately for advice on the next steps.

    Before giving your cat Benadryl or any medication, consult with a veterinarian to determine the safe dosage or if there is an alternative treatment better suited for your cat's situation.
