Simparica Trio flea, tick and worm protection for dogs
Simparica Trio is designed for pet parents who value simplicity without compromising on care. Simparica Trio offers a smarter way to protect your best friend with a single monthly chew.
By combining broad-spectrum parasite defence into one easy routine, it eliminates the need for separate treatments. Whether it’s deadly heartworm, paralysis ticks, or intestinal parasites, Simparica Trio covers the essentials so you can get back to what matters—spending time with your dog.
Why pet parents choose Simparica Trio
Simparica Trio is the go-to choice for households that want a "set and forget" approach to parasite prevention. One monthly liver-flavoured chew provides 6-in-1 protection by helping:
Prevent deadly heartworm disease.
Treat and controls fleas before they can lay eggs.
Defend against ticks, including the dangerous Australian paralysis tick.
Eliminate intestinal worms (roundworm and hookworm).
Clear mites and mange to keep skin healthy.

Safety Considerations
While Simparica Trio is a highly effective all-in-one solution, it is important to use the product responsibly to ensure the safety of both your pet and your household.
Animal Safety and Breeding
The safety of Simparica Trio has not been evaluated in breeding, pregnant, or lactating dogs. If your dog is intended for breeding or is currently nursing, consult your veterinarian before starting this treatment.
Additionally, use with caution in dogs with a history of seizures or neurological disorders, as the isoxazoline class of ingredients has been associated with adverse neurological reactions in some dogs.
Human Safety and Handling
Simparica Trio is designed for animal use only. To maintain a safe environment:
Keep out of reach of children: Store the product in its original packaging in a secure location to prevent accidental access.
Prevent accidental ingestion: In the event of human ingestion, seek medical advice immediately and show the product packaging or the Safety Data Sheet (SDS) to the healthcare professional.
Wash hands after use: Always wash your hands thoroughly with soap and water after handling the chew or administering it to your dog.
