Product Info

What is Interceptor?

Interceptor Flavor Tabs are a palatable once-a-month tablet that prevents heartworm disease, controls adult hookworms, and removes and controls adult roundworms and whipworm infections in dogs. Interceptor for cats is the only oral monthly preventative that protects against heartworms and removes adult roundworms and adult hookworms. Interceptor requires a prescription from your veterinarian.

For:

Dogs (4 weeks of age and weighing over 2 lbs), Cats (6 weeks of age and weighing over 1.5 lbs)

Benefits:

  • Given once a month
  • Easy to administer
  • Broad spectrum activity

How does Interceptor work?

Interceptor Flavor Tabs eliminate the tissue stage of heartworm larvae and the adult stage of hookworm, roundworm, and in dogs, whipworm infestations. The anthelmintic activity (destroying parasitic worms) of the active ingredient milbemycin oxime is believed to be a result of interfering with the invertebrates' neurotransmission.

Cautions:

Side effects of Interceptor are rare, but some animals may show signs of depression, drowsiness, vomiting, loss of appetite, diarrhea, hypersalivation, seizures, and weakness. If these or other symptoms develop, contact your veterinarian. Since humans can contract hookworm and roundworm from animals, you should maintain good personal hygiene. To prevent reinfection, cleaning up stool daily is recommended. Don't give your pet Interceptor if you are already administering another heartworm preventative.

Brand Name:

Interceptor (Elanco Animal Health)

Generic Name:

Milbemycin Oxime (mil-beh-my-sin ox-eem)

What is the most important information I should know about Interceptor?

Interceptor is a prescription medication FDA approved for use in dogs and cats. Interceptor is available as artificial beef (derived from pork and soy protein) flavored chewable tablets. The usual dose of Interceptor for dogs 2 to 10 pounds is 2.3mg (brown box), 11 to 25 pounds is 5.75mg (green box), 26 to 50 pounds is 11.5mg (yellow box) and 51 to 100 pounds is 23mg (white box) given once a month year round. The usual dose of Interceptor for cats 1.5 to 6 pounds is 5.75mg (green box), 6.1 to 12 pounds is 11.5mg (yellow box) and 12.1 to 25 lbs is 23mg (white box) given once a month year round.

What should I discuss with my veterinarian before giving Interceptor to my pet?

Tell your veterinarian if your pet has ever had an allergic reaction to Interceptor or milbemycin.

How should Interceptor be given?

Give Interceptor exactly as directed by the veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Heartworm testing should be performed prior to the start of prevention therapy. If your pet is off Interceptor for 6 months or less, start the medication and test after 6 months since microfilaria, that take 6 months to mature, will result in a positive test result. Store Interceptor at room temperature. Do not remove the tablet from its wrapper until ready to give the medicine. Keep this medication away from children and pets. Interceptor is safe for pregnant or lactating pets at a normal dose level.

What are the possible side effects of Interceptor?

Side effects of Interceptor are rare although some animals may exhibit depression, drowsiness, vomiting, loss of appetite, diarrhea, hypersalivation, seizures and weakness. If these or other symptoms develop contact your veterinarian.

What happens if I miss giving a dose of Interceptor?

Give the missed dose as soon as you remember. Do not give a double dose of the medication.

What happens if I overdose my pet on Interceptor?

Contact your veterinarian immediately.

What should I avoid while giving Interceptor to my pet?

Because humans can contract hookworm and roundworm from animals, it is important to maintain good personal hygiene. It is also important to eliminate fleas on your pet and in the household. To prevent reinfection, daily cleanup of stools is recommended.

What other drugs will affect Interceptor?

While Interceptor is safe to use in dogs at risk for MDRI-allele mutation (Australian Shepherds, Collies, Shelties, etc.), unless tested normal, caution is advised if your pet is also being given amiodarone (Cordarone), azole antifungals such as ketoconazole, carvedilol (Coreg), cyclosporine (Atopica), diltiazem (Cardizem), erythromycin (Ery-Tabs) or clarithromycin (Biaxin), quinidine, spironolactone (Aldactone), tamoxifen, and verapamil (Calan). Do not give Interceptor to your pet if your pet is already taking an alternate heartworm medication.
