I just gave my dog Credelio for the first time and now he seems a bit more tired than usual. Should I be worried about any side effects, Dial A Vet?

I gave my dog Credelio for the first time yesterday evening to help with fleas, and today he seems more tired than usual. I'm not sure if this is just a coincidence or if it could be a side effect of the medication. Is this something I should be concerned about, or does this kind of reaction fade on its own?

Answer

It's common to be concerned when your dog exhibits unusual behavior after starting a new medication like Credelio. While fatigue can sometimes be a side effect, it is often temporary and mild.

  • Fatigue can be a mild and temporary side effect of Credelio.
  • Monitor for other symptoms like vomiting or weakness.
  • If symptoms persist, consult with a veterinarian.

Credelio is generally safe and effective for combating fleas, but like all medications, it can cause occasional side effects. Lethargy or fatigue may occur as your dog's body adjusts to the treatment. It's important to keep an eye on your pet for any additional symptoms such as vomiting or signs of distress. If he seems to be back to normal within a day or two, it might have been a mild reaction. However, if he continues to seem unusually tired or you notice other concerning symptoms, consulting a vet would be wise.
