What are the side effects of cephalexin for dogs, and should I be concerned if my dog shows any symptoms?

I recently started giving my dog cephalexin as prescribed by our vet, but I've noticed she's been acting a bit differently since beginning the medication. She seems to be a little less energetic and has had some stomach upset. I'm concerned about whether these might be side effects of the cephalexin. Are these normal reactions to the medication, or should I be worried and contact the vet?

Answer

It's possible for cephalexin, an antibiotic prescribed for infections, to cause some side effects in dogs, including decreased energy and upset stomach. Monitoring these reactions is important to ensure your pet's well-being.

  • Decreased energy levels and lethargy
  • Stomach upset, such as nausea or vomiting
  • Diarrhea or loose stools
  • Rare but serious allergic reactions

These symptoms are known side effects of cephalexin, but they are usually mild and temporary. It matters because if symptoms persist or worsen, it may be necessary to adjust the medication or explore alternatives with your vet.

If you are concerned or notice any severe reactions, it's best to contact your veterinarian for advice. For online support, visit Dial A Vet to book a consultation with a professional.
