What is Trifexis® (spinosad + milbemycin oxime)?

Trifexis (spinosad + milbemycin oxime) is the monthly, beef-flavored tablet prescribed to kill fleas and prevent flea infestations, prevent heartworm disease, and treat and control adult hookworm, roundworm and whipworm infection in dogs. Trifexis requires a prescription from your veterinarian.

For:

Dogs (8+ weeks of age, weighing 5+ lbs)

Benefits:

  • Choose the Trusted, Triple Parasite Protection of Trifexis (spinosad + milbemycin oxime)
  • Protect your patients from heartworm disease, fleas and intestinal parasites with Trifexis
  • Easy to administer, beef flavored tablet

How does Trifexis work?

Spinosad, an active ingredient in Trifexis, starts to work within 30 minutes to kill fleas and has been proven to kill 100% of all biting fleas within 4 hours. Trifexis prevents heartworm disease by killing microfilariae and larvae from maturing into adult heartworms.

Cautions:

Serious adverse reactions have been reported following concomitant extra-label use of ivermectin with spinosad alone, one of the components of Trifexis chewable tablets. Treatment with fewer than three monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration, dogs should be tested for existing heartworm infection. Use with caution in breeding females. The safe use of Trifexis in breeding males has not been evaluated. Use with caution in dogs with pre-existing epilepsy. Puppies less than 14 weeks of age may experience a higher rate of vomiting. Consult your veterinarian for pregnant or lactating dogs.
