What is Trifexis?

Trifexis is a chewable tablet that kills fleas and prevents infestations, protects against heartworms, and treats and controls adult hookworm, roundworm, and whipworm infections. Trifexis requires a prescription from your veterinarian.

For:

Dogs (8 weeks of age and older and weighing at least 5 lbs)

Benefits:
  • Begins killing biting fleas within 30 minutes
  • Kills fleas before they can lay eggs
  • Prevents heartworm disease
  • Treats and controls roundworms, hookworms, and whipworms
  • Artificial beef flavor made from pork liver and hydrolyzed soy
  • Easy-to-administer chewable tablet
How it Works:

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 also kills flea eggs before they can mature, which helps to end the flea life cycle. 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. 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.

Rated 2 out of 5 by from Stopped working I have five dogs and five cats. I've been using Trifexis for years with no flea problem. All of a sudden the last two months it works for two weeks and then is completely useless for the next two weeks. The flea problem is so bad in my house right now after only three and a half weeks past the last dose that I'm embarrassed to have people over, and I've had to hire someone to come spray my house for them. I've ordered a different topical product that will be here next week but until then my poor animals, and kids as well have to suffer from fleas. I pulled 35 fleas off two of my youngest fur babies just tonight. I've been getting roughly 30-40 a day off of them, for a week that's with the medication in their system. I pray they don't die of exsanguination before the new meds get here.

Rated 5 out of 5 by from My eight yr old Shih-Tzu named Harley.... She's been using this product and nothing else (I thought that her shot for heartworm covered the three preventatives) for as long as I can remember. Her sister takes a different form from the vet for fleas/ticks/heartworm in a single shot that feels nicer on me anyway. My poor baby Harley is allergic or just cannot physically take pills. This product does even more than stated. My pup loves it like a treat, she's never had any issues with it and unlike drops, it does not give my pup a bad hair week. :) I cannot recommend this product enough except it would be nice if it came in a six month shot. You won't be dissatisfied purchasing it.

Rated 5 out of 5 by from PET FRIENDLY AND EFFECTIVE I'm extremely pleased with this Trifexis. I have a miniature poodle who weighs about 18-20lbs. He hasn't had any side affects, and he thinks it's a treat, so he willingly takes it with no problem!!

Rated 3 out of 5 by from DOES NOT LAST A FULL 30 DAYS My vet originally had my 5lb Yorkie on Comfortis and I loved it. Comfortis would last a full 30 days plus easily. I notice with using Trifexis it last a good 3 weeks so frustrating! I have a little dog and it just does not last long at all. I live in a neighborhood that is very active with pets (dogs and cats). I need something that is strong and will last 30 days.

Rated 5 out of 5 by from Trifexis 10.1 - 20 lbs The vet gave us a 1 months worth for my two babies. It has worked beautifully. They were chewing themselves up but we couldn't find any fleas, the vetonly found one. She said they were chewing cause they have an allergy to the fleas. There is no infestation of them just a single bite became torture for them. I opened the pill package and it smelled like bleach, it was bad. My dogs wouldn't touch the pill. I crushed it up and mixed it in peanut butter, they knew something was odd about it but heck it was in peanut butter, they wanted that peanut butter so they slowly ate it. They didn't get sick but my smaller baby became just a little lethargic but by the next day he was ok. I will be giving this to them again. Not eagerly because I prefer natural methods but I have tried all the natural methods and they were not working. I can't stand watching them be tortured over flea bites. They were covered in scabs from chewing on themselves in the same spot. I will use it again and again until there is something natural and just as affective, but I don't see that happening.

My 8 month old morkie is 9 pounds and may still grow a pound should he take 10-20 dosage

Asked by: Laners
The 5-10 pound dose of Trifexis is recommended for dogs up to 10 pounds. Therefore, this is the dose you should be giving. If your dog does gain weight and is 10.1 pounds or greater, you would increase his monthly dosage to the 10-20 pound dose.

I'm confused about dosage. My mastiff is currently 35 lbs but someday will be around 100 lbs, so what dosage is right for her for this month? and next, etc?

Asked by: lizzysmith
Your dog would need the 20-40 pound dose monthly until its >40 pounds. When your dog is 40.1 pounds or greater it would use the 40-60 pound dose monthly until it is >60 pounds. At this point, your dog would use the 60-100 pound dose monthly. If your dog becomes greater than 100 lbs you wil need to give multiple tablets to account for its weight. Your vet can order only one month at a time if they believe your dog will be in the next weight category next month.

Does Trifexis prevent Mosquito's from biting? It's my understanding that mosquito bites are the leading cause of heart-worms.... But the product packaging and info makes no reference to preventing them.

Asked by: Vicky
Trifexis does not prevent mosquitos from biting, it works by killing microfilariae and larvae from maturing into adult heartworms.

My dog weighs around 135 lb. Will the highest dose (60-120 lb) be satisfactory for him?

Asked by: Timsmom
Talk to your veterinarian. He may start your dog on that dose or they may want to give him a combo of the tablets.
