With flea medicine, heartworm preventive and intestinal parasite control in one, get the peace of mind that comes from protecting your canine companion.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.
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 gastrointestinal 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.
