What are the differences between Interceptor and Iverhart Plus?

Your first impression might be that these products are a lot alike. There are, in fact, many similarities. Both of these monthly treatments are chewable and easy to administer. They are both safe for pregnant or breeding female dogs, and they both require a prescription from a veterinarian.

These products are also both safe for puppies. Iverhart Plus can be given to puppies over 6 weeks old, while Interceptor is safe for puppies 4 weeks and up weighing at least 2 pounds. These formulas both work to prevent heartworms, and they both protect your pet against hookworms and roundworms.

Although these two products have many similarities, they are also different in many ways. Firstly, they both offer a different flavor. Interceptor features a tasty beef flavor, and Iverhart Plus is deliciously pork-flavored. Tri-Heart Plus is only safe for use in dogs, while Interceptor can be used in cats or dogs.

These products also have different active ingredients. Iverhart Plus contains Pyrantel Pamoate and Ivermectin, and Interceptor contains Milbemycin Oxime. Unlike Iverhart Plus, Interceptor is proven safe for use in lactating dogs. Interceptor also protects against whipworms, while Iverhart Plus does not.

Choosing between Interceptor and Iverhart Plus

As you can see, these two products are both incredible options for protecting your pet against parasites. However, the differences between these medications can help you decide which formula is best for your pet. If you have a cat, a lactating dog, or a puppy between 4 and 6 weeks old, you’ll want to choose Interceptor. If none of these categories describe your pet, you may choose either of these effective options. If you’re searching for a product that protects against whipworms, Interceptor might be best.

The next step in protecting your pet is to speak to your vet. Your veterinarian will be able to walk you through your decision and answer all of your remaining questions before prescribing a medication for your pet. If you’ve already spoken to your vet and you think of another concern or question, feel free to contact the Allivet pharmacists for a convenient, over-the-phone pet parent consultation!
