What is Interceptor for Dogs?

Understanding the Basics

Firstly, as a caregiver, you need to know what you’re dealing with when it comes to Interceptor for dogs. Interceptor is a medication primarily used to prevent heartworm disease in dogs. It’s an oral medication, so you’ll be able to administer it easily, without any hassle.

The Active Ingredients

Interceptor treatment comprises two main active ingredients:

  1. Milbemycin Oxime
  2. Praziquantel

Milbemycin Oxime is responsible for preventing heartworm disease, while Praziquantel is effective against tapeworms. Together, they provide a comprehensive protection against these parasites.

The Importance of Prevention

Interceptor is not just a treatment, but it’s also a form of prevention. A heartworm infestation can be fatal for your dog. It’s far better to prevent the disease than to treat it.


  • Prevention is better than cure
  • Regular use of Interceptor can ensure your dog stays healthy

Administering Interceptor

Interceptor is easy to administer. It’s a tasty, chewable tablet that most dogs will happily take. If your dog is less eager, try hiding the tablet in their favorite treat. You should give your dog Interceptor once a month, ideally on the same day each month.

Potential Side Effects

Interceptor is generally safe, but like all medications, it has potential side effects. These can include:

  • Vomiting
  • Diarrhea
  • Depression
  • Loss of appetite

If you notice any of these symptoms, consult your vet immediately.
