Get fast-acting parasite protection for your dog in just one tablet every month. Trifexis not only prevents heartworm disease in dogs, but also treats and controls intestinal worms including roundworms, whipworms and hookworms. Trifexis also delivers fast-acting flea treatment and flea infestation prevention, starting to kill fleas within 30 minutes of application and killing 100% of fleas on your dog within just 4 hours. It’s no surprise why Trifexis has been protecting dogs from parasites for nearly 10 years with more than 272 million doses distributed.* When untreated, intestinal worms and fleas can cause serious symptoms and major discomfort for your dog. Intestinal worms are common parasites – even for indoor dogs – and can cause vomiting, weight loss and diarrhea. And flea bites aren’t just painful, they can cause serious skin issues and spread disease. That’s why Trifexis makes protecting your dog easy. Packing triple parasite protection into a single, once-a-month, beef-flavored tablet delivers the ultimate convenience in care. No need for greasy topical applications or flea collars. Check the product label for information on application and potential side effects. Dogs must be at least eight weeks old and weigh between 10.1 and 20 lbs. to use this Trifexis formula. You can also find Trifexis available for dogs that weigh as few as 5 lbs. or for dogs weighing up to 120 lbs. Trifexis is only available by prescription. Subscribe to regular doorstep deliveries of Trifexis 6-dose packs so you never miss a monthly treatment. Before starting any heartworm prevention program, it’s important for your veterinarian to test your dog for an existing heartworm infection. At your next visit, tell your veterinarian you want the convenience of triple parasite protection for your dog so you can enjoy peace of mind from the backyard to the dog park.
