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 it Works:

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 Interceptor:

Interceptor is given once a month for the prevention of heartworm disease in dogs and cats. Interceptor also protects against hookworm, roundworm and in dogs, whipworm. It is recommended by the American Heartworm Society that heartworm prevention be used year round. Interceptor is used "off label" in the treatment of sarcoptic mange in dogs.

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.

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.

How should this medication 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 happens if I miss giving a dose:

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

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 and to not feed your pet rodents or uncooked meat or fish. To prevent reinfection, daily cleanup of stools is recommended.

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 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.

How to Use
Directions:
  • Give Interceptor Flavor Tabs once a month on the same day of each month year round.
  • Interceptor Flavor Tabs can be given to dogs and cats.
  • Watch pet closely following dosing to be sure the entire dose has been swallowed. If it is not completely swallowed, give one more full recommended dose as soon as possible.
Tip:

Do not remove from its wrapper until ready to give to pet.

Rated 5 out of 5 by from Good results I like to keep Halo in as good a shape as I possibly can and Interceptor seems to be helping me to achieve that goal. I've been using it for almost a year now and have seen no adverse reactions to this med.

Rated 5 out of 5 by from Great for MDR1 Dogs! The brand that also contains a flea preventative made my MDR1 dog sick. Dogs with the MDR1 mutation do not tolerate multi-ingredient medicines as well. The basic Interceptor is great and does not cause any side effects for my collie. If your dogs get sick on other brands get your dogs tested for the MDR1 mutation and try this basic Interceptor.

Rated 5 out of 5 by from Effective and doesn't make my dogs sick like other I am very happy with Interceptor. My dogs were on Trifexis before which always gave them an upset stomach after taking it. I switched to Interceptor which is much more cost effective and no harsh side effects on my dogs.

Rated 5 out of 5 by from Super product! Rescued our dog who was full of parasites and very ill. Interceptor keeps her healthy and she's now like a 4 year old puppy!

Rated 5 out of 5 by from No Bad Side Effects! I have used many other Heart worm preventatives, and my dog had side effects for many days afterwards such as vomiting, malaise, and scratching. Not with Interceptor. No side effects were noted with my Jesse, and he takes it without me having to hide it in a treat. He thinks the pill IS a treat!

My dog weighs 115lbs. Interceptor and heart guard only goes to 100lbs. How should I purchase this?

Asked by: Lyndz
Buy the pill for 100 pound weight. Call the company for confirmation regarding a correct answer.

Dosage

Can a pill be split into more than one dose if it is meant for a larger dog. Dog weighs 6 lbs and pill is for 26 t 50 lbs. Use 1/5 of the pill???
Asked by: Mary
Pill splitting is not recommended because the pills have added ingredients to make the pill and the active ingredient in the pill may not distribute evenly. You need to use a pill that is recommended based on your dog's weight.

Cat vomited 1 roundworm

Is it possible for a cat to have 1 roundworm? He vomited up 1 worm, we took him to the vet and we were given Interceptor. I was expecting any existing worm to come out in his feces but we still haven't seen anything. Was interceptor the right thing to give him?
Asked by: Anonymous
yes (although unlikely), and yes.
