Answer

It's important to be aware of potential side effects when your dog is taking lomustine, a medication often used in cancer treatment. Knowing what to watch for can help ensure your pet remains comfortable and well-cared for.

  • Milld to moderate gastrointestinal upset may occur
  • Risk of decreased white blood cell count leading to increased infection risk
  • Long-term concerns include liver damage with extended use

Lomustine is a chemotherapy medication that can cause side effects in dogs, similar to those in humans. Common side effects include gastrointestinal upset, like vomiting and diarrhea, as well as decreased appetite. It's crucial to monitor your dog's white blood cell count, as lomustine can lead to bone marrow suppression and increase infection risks. Extended use may also cause liver damage, so regular liver function monitoring is advised. Always consult with your vet if you notice any unusual symptoms or believe your dog's condition is worsening.
