How long do side effects from Simparica Trio typically last for dogs?

We gave our dog Simparica Trio yesterday, and today he seems a bit off — he's been acting more lethargic than usual and didn't seem interested in his dinner. I'm worried about any side effects he might be experiencing. How long do these typically last, and should I consider taking him to the vet if these symptoms persist?

Answer

It's not uncommon for dogs to experience mild side effects after taking Simparica Trio, a comprehensive parasitic treatment. If your dog seems lethargic and has a reduced appetite, these symptoms usually resolve within 24 to 48 hours.

  • Mild lethargy
  • Decreased appetite
  • Nausea or digestive upset

These side effects are typically temporary and should gradually improve as your dog's system adjusts to the medication. However, it's important to monitor your pet closely. If the symptoms persist beyond two days, significantly worsen, or if new symptoms arise, it's a good idea to consult with a veterinarian.

For ongoing concerns or if your dog's condition appears to deteriorate, please book a consultation with a vet at Dial A Vet.
