How do Iverhart Plus and Trifexis differ?

These two medications have many features in common. Perhaps the most notable similarity is that both of these prescription products protect dogs against heartworms, roundworms, and hookworms. Both formulas are made to be administered monthly, and they both come in the form of a tasty, chewable tablet. Iverhart Plus offers a pork flavor, and Trifexis is beef-flavored. Finally, both products are safe for use in puppies. Iverhart Plus can be used in puppies as young as 6 weeks of age, while Trifexis can be given to puppies over 8 weeks old weighing a minimum of 5 pounds.

These formulas are also unique from one another in many ways. Iverhart Plus contains Ivermectin and Pyrantel Pamoate, and it is safe for use in pregnant or breeding dogs.

Trifexis offers an entirely different duo of active ingredients - Milbemycin Oxime and Spinosad. In addition to the parasites listed above, Trifexis offers added protection against whipworms. It also works to kill fleas, going to work to eliminate all biting fleas within just 4 hours. This formula has not been proven safe for use in pregnant, breeding, or lactating dogs.

How can I make the choice between Iverhart Plus and Trifexis?

Choosing between these two products can be challenging. After all, you truly can’t go wrong when you elect to keep your dog healthy with either of these incredible medications. However, there are a couple of ways to make this important decision.

Firstly, will you be treating a pregnant or breeding dog? If so, Iverhart Plus is the safest choice. Secondly, are you concerned with protecting your dog against fleas and whipworms? If your dog is already taking a flea and tick preventative, he or she may not need the broad-spectrum protection provided by Trifexis. If your pup isn’t on any such medication, Trifexis could be the best choice for your beloved canine companion.
