Trifexis® Chewable Tablets for Dogs

Trifexis is a monthly, chewable tablet for dogs that kills fleas, prevents heartworm disease, and treats and controls adult hookworm, roundworm, and whipworm infections. Trifexis combines two trusted active ingredients to provide protection for your dog against these dangerous parasites. Trifexis starts working within 30 minutes from administration of this medicine to kill fleas and has been proven to kill all biting fleas within four hours. Trifexis also kills flea eggs before they can mature, which puts an end to the flea life cycle. Trifexis prevents heartworm disease by killing microfilariae and larvae from maturing into adult heartworms. Trifexis comes in a tasty beef-flavored tablet (made from pork liver and hydrolyzed soy) for ease of administration to your dog.

Item Specifications:

Benefits:
Trifexis is used to prevent heartworm disease, and treat and control adult hookworm, roundworm and whipworm infections.

For Use:
Dogs (at least 8 weeks of age and weighing at least 5 lb.)

Strength/Size: X-small (Pink) for dogs 5-10 lb.
Small (Orange) for dogs 10.1-20 lb.

Xlarge (Brown) for dogs 60.1-120 lb.

Active Ingredient(s):
Spinosad, milbemycin oxime

Cautions:
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. Make sure to tell your veterinarian what other medication you are giving to your pet. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your veterinarian may vary the dose and/or monitor your pet more closely. This medication is generally well tolerated with other commonly prescribed medications. Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together. Allergic reactions to medications may occur. Be sure to inform your veterinarian if your pet has any known drug sensitivities or allergies. If your pet displays symptoms of an allergic reaction, call your veterinarian immediately or go to a veterinary emergency clinic. Symptoms may include but are not limited to: swollen lips, tongue, face, airways; difficulty breathing; agitation; profuse salivation; vomiting; widespread hives and itching.

Side Effects:
Side effects may include nausea, vomiting, diarrhea, loss of appetite, decreased activity, itching, redness and inflammation of the skin. If you notice anything unusual, contact your veterinarian.

Usage:
Trifexis should be given orally as directed veterinarian. Give Trifexis with food for maximum effectiveness.

Our dogs have used this combination Flea and Heartworm medication for several years and it really works! We have never seen a flea, even in the Summer and are grateful that our girls have the added protection against the worms. Happy that we discovered our "Go-To" product online at a more affordable cost.

For years, I never had a flea problem with any of my dogs, in fact I could get by with just bathing them. But over the years, the fleas moved into my yard and the dogs would get a few. I used all of the different messy topicals until each stopped working. Trifexis has been a miracle, especially for my Whippet-Australian Shepard mix. He looked like he had psoriasis and was just miserable, turns out it was a flea allergy! After a short time on Trifexis, his skin healed and his hair grew back!

NORMA C on Jun 20, 2018
I have three dogs, with one allergic to topical flea/tick applications. Even though Trifexis upsets their tummies the first day, it seems to be the best alternative to topical medications. The Trifexis really does keep the fleas and ticks at bay.
