Frequently Asked Questions
What is Simparica TRIO and what does it protect against?
Simparica TRIO is a monthly tablet that protects your dog against fleas, ticks, heartworm, roundworms, hookworms, mites, mange and even mosquitoes in one single dose.
How do dogs get heartworm, and can Simparica TRIO prevent it?
Heartworm is transmitted through mosquito bites and presents risk year-round for dogs across Australia. TRIO’s triple attack on heartworm is 100% effective in preventing deadly heartworm disease and works by protecting against new heartworm infections, killing juveniles already in the bloodstream and killing the mosquitoes that spread it.
Can Simparica TRIO be given to heartworm-positive dogs?
Yes, Simparica TRIO is safe for use in heartworm-positive dogs. For dogs switching from another heartworm prevention product, it can be started within one month of the last dose. If you know or suspect your dog has an existing heartworm infection, always check with your vet.
How do dogs get fleas and ticks in Australia, and how do I treat them?
Fleas spread easily. It could be from other animals, shared environments, and even your own backyard. Ticks (including paralysis ticks) are commonly found in bushland, long grass, and coastal areas from Queensland down to Victoria. Simparica TRIO is a fast-acting flea and tick treatment for dogs that starts killing fleas within 4 hours and ticks within 8 hours, with protection lasting up to 35 days.
Is Simparica TRIO safe for all dog breeds, including Collies?
Yes. Simparica TRIO has a well-established safety profile and is well tolerated in avermectin-sensitive breeds, including Collies. However, like all medications, if your dog has known sensitivities or underlying health conditions, it’s always best to check with your vet.
Can Simparica TRIO be given alongside other medications?
Simparica is generally well tolerated alongside other medications. That said, it’s best to consult your vet first if your dog on any other treatments, supplements, or medications before starting.
