What are the side effects of zonisamide in dogs?

Yesterday evening, I started my dog on zonisamide as prescribed. I'm trying to keep an eye on him for any unusual changes, but I'm not sure what side effects to expect. Can you let me know what signs to watch out for and if there are any I should be particularly concerned about?

Answer

Zonisamide is a medication commonly prescribed for dogs with seizures, and while it is generally well-tolerated, it’s important to monitor your dog for potential side effects.

  • Sleepiness or lethargy
  • Ataxia (unsteadiness or difficulty walking)
  • Decreased appetite
  • Vomiting or diarrhea
  • Panting or increased thirst

These side effects are typically mild, but it's important to note any significant changes in behavior or health. If your dog experiences severe symptoms, such as persistent vomiting, difficulty walking, or severe lethargy, consult your veterinarian as these could indicate a more serious reaction.

If you notice anything concerning or have more questions about your dog's health on zonisamide, it's always best to consult with a veterinarian. You can book a consultation with Dial A Vet for personalized advice.
