Uses

Trifexis prevents heartworm disease. Trifexis kills fleas and prevents flea infestations, and treats and controls adult hookworm, roundworm and whipworm infections in dogs and puppies 8 weeks and older and 5 pounds or more.

Possible Side Effects

When used as prescribed, side effects while using Trifexis are rare. Symptoms of GI distress and skin irritation can occur. Vomiting, diarrhea, lethargy, lack of appetite, and itching and reddening of the skin have been reported. Vomiting may be more likely in puppies under 14 weeks of age. If your dog is truly allergic to Trifexis or to the dying of parasites, she may exhibit symptoms such as facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If your dog experiences any of these symptoms, call your veterinarian or a local emergency veterinarian immediately.

Drug & Food Interactions

Always communicate with your veterinarian about any medications, vitamins, or supplements your dog is already taking. Some serious adverse reactions have been documented when used with other spinosad and ivermectin medications simultaneously. No known food interactions have been reported.

Precautions

The use of ivermectin at higher than FDA approved doses at the same time as Trifexis can result in serious side effects. Treatment with fewer than three monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration of Trifexis, 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. The most common adverse reactions reported are vomiting, decreased activity, itching, decreased appetite, and diarrhea. To ensure heartworm prevention, observe your dog for one hour after administration. If vomiting occurs within an hour of administration, re-dose with another full dose. Puppies less than 14 weeks of age may experience a higher rate of vomiting. For complete safety information, please see Trifexis product label or ask your veterinarian.

FAQ

What Is Trifexis (Spinosad + Milbemycin Oxime), And What Does It Protect Against?

Trifexis is a monthly, chewable tablet for dogs. Trifexis kills fleas and prevents flea infestations on dogs, treats and controls adult hookworm*, whipworm and roundworm infections, and prevents heartworm disease. Trifexis is for use in dogs and puppies 8 weeks of age or older and 5 pounds of body weight or greater. If you do not administer Trifexis monthly throughout the year, continue administering the medication for at least three months following the last exposure to mosquitoes.

What Are Some Of The Benefits Of Trifexis?

  • Trifexis is an oral monthly product that rapidly kills fleas on dogs and is effective in preventing heartworm disease and treatment and control of adult hookworm (A. caninum), adult roundworm and adult whipworm infections in dogs and puppies 8 weeks of age or older and 5 pounds of body weight and greater.
  • Trifexis is approved by the FDA as safe and effective when used according to the label.
  • Spinosad, one of the active ingredients in Trifexis, began to kill fleas on dogs 30 minutes after administration with 100% effectiveness within 4 hours in a well-controlled laboratory study.
  • Trifexis continues to kill fleas for a full month after treatment.
  • Dogs with signs of flea allergy dermatitis showed improvement in erythema, papules, scaling, alopecia, dermatitis/pyodermatitis and pruritus (itching) as a direct result of eliminating the fleas.
  • Trifexis is available in five strengths. Each tablet is formulated to provide a minimum dosage of 13.5 mg/lb (30 mg/kg) spinosad and 0.2 mg/lb (0.5 mg/kg) milbemycin oxime according to body weight.

How Well Does Trifexis Work?

  • In a well-controlled laboratory study, Trifexis was 100% effective against induced heartworm infections in dogs when administered for three consecutive monthly doses.
  • In well-controlled laboratory studies, a single dose of Trifexis at labeled dose was effective in removing roundworms, whipworms and hookworms (A. caninum).
  • In a well-controlled laboratory study, spinosad alone began to kill fleas 30 minutes after administration and demonstrated 100% effectiveness within 4 hours.
  • Spinosad kills fleas on dogs before they can lay eggs. If a severe environmental infestation exists, fleas may persist for a period of time after dose administration due to the emergence of adult fleas from pupae already in the environment. In field studies conducted in households with existing flea infestations of varying severity, flea reductions of 98.0 to 99.8% were observed during the course of three monthly treatments with spinosad alone. Dogs with signs of flea allergy dermatitis showed improvement in erythema, papules, scaling, alopecia, dermatitis/pyodermatitis and pruritus (itching) as a direct result of eliminating the fleas.

    Fast shipping, good support

    By RocketDogIsBest on Nov 15, 2021

    I have never ordered from Chewy before. I did contact them regarding the order. I found their support services pleasant. They did exactly what they said they would do. Their follow through was excellent. The price of the product was better than most. That means a lot to me since I am on a fixed income. I'll stick with Chewy.

    Different Box

    By Sully on Sep 15, 2021

    I just received the Trifexis I ordered for my two little pooches. This is my first time ordering meds from Chewy. I'm a little leery because the boxes are totally different than I've ever had with Trifexis. I've been giving my dogs this for 10 years, and I've never had a box look like this. Wondering if they're counterfeit...... ? Don't know what to do.

    Trifexis for Tootie

    By Taco on Sep 7, 2021

    In the last year, Tootie was diagnosed with Cushings.....Had her Trifexis delivered and the next day at dr's appointment her new weight was less. She was in need of the orange box (not the green box) I was very impressed that chewy said they would swap the meds I just received and I could order the new size. GREAT CUSTOMER SERVICE THANKS

    Happy customer

    By sammy on Aug 20, 2021

    This is the first time I ordered from Chewy and I was pleased with the service. Only problem I experienced was not the fault of Chewy. This is a prescription item and delay was caused by my vet...not intentional. It is easy to reach customer service at Chewy and they are very easy to work with. I definitely will be ordering other items from Chewy as well as prescription items as needed.

    By katie on Sep 7, 2021

    I don't know if it's the dosage or the ingredients but this stuff does not seem to work. My dog has been on this for 3 months and it does not seem to work at all. He keeps getting fleas despite the treatment, baths, and constant brushing.
