Just noticed I applied old Revolution on my cat without checking the expiration date—should I be worried or is it still effective?

This morning, I realized that I accidentally put an expired dose of Revolution on my cat without checking the date first. I’m worried about whether it still works like it’s supposed to, or if that could somehow harm her. Should I be concerned about this, or will it still protect her as it should?

Answer

It’s understandable to be concerned after using an expired product on your cat. While expired Revolution may not be as effective, it's unlikely to cause harm.

  • Check your cat for any unusual symptoms or reactions.
  • Expired medication may have reduced effectiveness.
  • Consult a vet if you notice any adverse effects or are worried about protection levels.

Applying expired Revolution to your cat is generally not dangerous, but it might not work as well as intended. Revolution is mainly a parasiticide, and while the expiration date can affect its efficacy, it is unlikely to be harmful. Monitor your cat for any unusual symptoms and consider getting a fresh dose to ensure protection against parasites.
