What is Simparica Trio?

Simparica Trio is a chewable tablet administered monthly to dogs for protection against heartworm disease, ticks and fleas, roundworms, and hookworms. It combines three active ingredients—sarolaner, moxidectin, and pyrantel—each playing a crucial role in preventing and treating these conditions.

Why Weight Matters

The dosage of Simparica Trio is dependent on the dog’s weight. This ensures that each dog gets the right amount of medication necessary for effective prevention and treatment, minimizing the risk of underdosing or overdosing.

Simparica Trio Weight Ranges

Simparica Trio comes in five different weight ranges:

  1. 2.8-5.5 lbs (1.3-2.5 kg)
  2. 5.6-11 lbs (2.6-5 kg)
  3. 11.1-22 lbs (5.1-10 kg)
  4. 22.1-44 lbs (10.1-20 kg)
  5. 44.1-88 lbs (20.1-40 kg)
  6. 88.1-132 lbs (40.1-60 kg)

If your dog’s weight is on the border of two weight ranges, it is generally recommended to use the higher dose to ensure full protection.

Administering the Right Dosage

Each weight range has a specific amount of active ingredients, tailored to provide the correct dosage for that weight. Here’s a breakdown of the dosage per weight category:

  • 2.8-5.5 lbs: Sarolaner 3 mg, Moxidectin 0.06 mg, Pyrantel 12 mg
  • 5.6-11 lbs: Sarolaner 6 mg, Moxidectin 0.12 mg, Pyrantel 25 mg
  • 11.1-22 lbs: Sarolaner 12 mg, Moxidectin 0.24 mg, Pyrantel 50 mg
  • 22.1-44 lbs: Sarolaner 24 mg, Moxidectin 0.48 mg, Pyrantel 100 mg
  • 44.1-88 lbs: Sarolaner 48 mg, Moxidectin 0.96 mg, Pyrantel 200 mg
  • 88.1-132 lbs: Sarolaner 96 mg, Moxidectin 1.92 mg, Pyrantel 400 mg

When the Dog Outgrows the Weight Range

As your pet grows or gains weight, you’ll need to adjust the dosage accordingly. For instance, if your dog weighed 40 lbs and was using the 22.1-44 lbs dosage but has since grown to 50 lbs, they should be moved to the 44.1-88 lbs dosage.

Safety Precautions

While Simparica Trio has a high safety margin, meaning an accidental overdose is typically not dangerous, it’s crucial to administer the right dose to avoid any potential side effects. In cases of uncertainty, always consult your vet for the appropriate dosage.

Frequently Asked Questions

1. Can I administer Simparica Trio to a dog smaller or larger than the indicated weight ranges?

Simparica Trio is specifically formulated for different weight ranges to ensure maximum efficacy and safety. Therefore, giving your dog a dosage meant for a different weight range is not recommended. In the case of dogs exceeding the maximum weight range of 132 lbs, you should consult with your vet for the best way to administer the appropriate dosage.
