What are the side effects of ivermectin for dogs?

I recently gave my dog ivermectin as part of their regular heartworm prevention, but I noticed he's been acting a bit off afterwards. He seems a bit lethargic and isn't eating as much as usual. Are these normal side effects, or should I bring him to the vet to be checked out?

Answer

After giving your dog ivermectin for heartworm prevention, mild side effects like lethargy can occur, but it's crucial to monitor any changes closely.

  • Look for symptoms such as extreme lethargy, vomiting, diarrhea, or disorientation.
  • Consider how quickly symptoms appeared after administering the medication.
  • Contact a vet if symptoms persist or worsen over time.

Understanding these symptoms is important because some dogs are sensitive to ivermectin, especially certain breeds like Collies and Australian Shepherds. While mild side effects might not indicate a serious issue, sudden or severe reactions should be addressed promptly to ensure your pet's safety.
