Just started my dog on 20mg of fluoxetine for aggression, and he seems more hyper? Is this normal?

I recently started my dog on 20mg of fluoxetine to help manage his aggressive behavior, but since then, he seems to have become more hyper than usual. He's been more energetic and restless, which is quite different from what I expected. Is this a common reaction when beginning this medication, or should I be concerned about his sudden change in energy levels?

Answer

It's understandable to be concerned about your dog's unexpected increase in energy after starting fluoxetine, a medication commonly used to manage aggressive behavior. While some dogs may exhibit heightened energy or restlessness initially, these effects usually diminish over time.

  • Increased energy can be a temporary side effect.
  • Monitor your dog for other unusual behaviors.
  • Consult a vet to evaluate the medication's appropriateness.

Fluoxetine, similar to other medications affecting neurotransmitters, may initially cause changes in your dog's behavior, such as hyperactivity or restlessness. These changes are sometimes part of the adjustment process, but if they persist or worsen, it's essential to consult with your veterinarian to ensure the dosage and medication are still suitable for your dog's needs. Always monitor your pet closely during the initial phase of any new medication.
