Indication

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.

Important Safety Information

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, redose 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.

So dissapointed

Had a coupon for 20% off heartworm and tick medication. Call it in gave them the code numbers for my auto shipment and was assured it would be taken off my order. Ask once again if it was in. Called when shipped without the discount and was told there was no record of it. They said nothing they could do. I thought so highly of Chewy before this. Will tell all my fellow pet friends how they did not live up to their word.

not the same as from the vet

We used to get this medication from or Vet before she retired..started to order it from here with our new vet and it's NOT the same as from our old Vet! These were non effective,meaning our dog got a terrible case of fleas..treat everything around us and gave it another try..nope,still nothing!Will not buy again nor recommend!

wouldn’t recommend

My dog has been on this prevention for a while and every month she would get runny stool a couple days after eating. Never thought to look at the side effects because this is what the vet gave us. Me not knowing just thought it could’ve been a treat but it in fact isn’t. Tried to get a refund from chewy and they won’t do it because her side effect was on the list. Very disappointing since I’ve been a customer since 2017. Word of advice check the side effects before giving it to your dog. My poor girl has been miserable with upset stomachs every month. It does work but the side effects are to long and if your dog encounters an effect it sucks to see them miserable..

Love ordering from Chewy!

Ordering from Chewy is so easy, I’ve been getting food for a couple of years. Then I tried dog treats and Major loves them. My vet no longer carries Trifexis, but Your prices were the same as the local pet store and it’s usually delivered next day.

Can't get my Labradors to tke this medication. Tried pulverized in food and with peanut butter. Even I can smell it. Dogs refused to swallow it. I am discounting and going Back to Hartz .

Effective, not tasty.

Effective product . Only problem is my German Shepherd will NOT eat the tablet. Now my Australian Shepherd will Not eat the tablets either . I have to split the pills and put down their throats , so four times a month.

Medication

Works well never see any fleas and they have always tested negative for heart worms. The one bad thing is I have to break them up and hide them in pill pockets, tuna, chicken, or whatever else I can think of. My golden and lab mix have no problem sniffing them out and eating around them. Chewy gets them to me timely.

Great for my Boy

Love Chewy! Been my go to for years and years. Sent me flowers when my last Boy passed. Buy all my Boys food from them. However the last Representative I spoke with was so rude and disrespectful think about changing where I buy his food and prescriptions.
