What makes Interceptor and Sentinel different from one another?
These two top-of-the-line products are similar in a broad range of ways. They are both chewable, once-monthly, prescription-only medications with a tasty beef flavor. Both formulas contain Milbemycin Oxime as an active ingredient. Both products are safe for use in lactating, breeding, or pregnant dogs, and they can both be administered to puppies ages 4 weeks and up (Interceptor should only be given to puppies weighing at least 2 pounds). Finally, both of these products are heartworm preventatives, and they both protect against whipworms, roundworms, and hookworms.
The key advantage of Interceptor is that it is safe for use in cats. Sentinel differs from Interceptor in that it contains a second active ingredient - Lufenuron. This ingredient works to break the life cycle of fleas. It stops developing flea larvae and eggs, but it does not eliminate existing flea infestations.
Key takeaways on Interceptor vs. Sentinel
As you can see, there are a number of similarities that make these products equally effective in a variety of ways. However, there are a couple of factors that might help you choose between the two. If you have a cat, the safe option for your feline family member is Interceptor. If you’re searching for a broad-spectrum product that protects your dog against developing fleas, Sentinel is a great choice.
Your next step is to make an appointment with your veterinarian. Your vet can weigh in on your decision and help you make the best choice for your individual pet based on his or her health history. He or she can also address any concerns and answer any questions you may have.
