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.

How to Use
Directions:
  • Give Interceptor Flavor Tabs once a month on the same day of each month year round.

Customer Reviews
Interceptor is rated 4.7 out of 5 by 554.
Rated 5 out of 5 by from Great overall product We use this on our Labrador-mix and American Bulldog and have never had an issue with fleas or ticks on them or or us. We also have not had problems with mosquitos or biting flies bothering them.

Rated 5 out of 5 by from Life saver for my Greyhound! My vet recommended Interceptor as I was convinced my sweet Greyhound became ill every month when I gave her Heart Guard. She would have an upset stomach and diarrhea for days after receiving it. My vet explained I wasn't crazy, some dogs were indeed allergic to the main ingredient in Heart Guard but still need protected from heart worms so suggested Interceptor as it did not possess the ingredient making my dog ill. He was right! Six months now on Interceptor and she happily takes it burried in a piece of cheese (it is a hard chew instead of a soft chew like Heart Guard), and remains ill/symptom free. Wonderful product for a dog with allergies to Heart Guard!!

Rated 5 out of 5 by from Does so much good Our vet recommended this product to get rid of the worms our dog gets, and also to protect her from heart worms. We live in an area where the mosquitos are healthy and abundant. Protecting our littler girl from heart worms is very important to us.

Q&A

My dog hates taking any form of heartworm protection, I can only give them to her orally. How big are this pills? Will they be easy to swallow of will i have to cut them into pieces?

Asked by: kcalta
These pills are not very big. They are also flavored chewables to make it easier for pets to eat. They can be cut up/crushed and given with food if that will help. Just make sure the pet gets the full dose and swallows it, otherwise you will need to try again. Hope this helps.

We have a new puppy and she's 3 months old. Our vet gave us a sample of Interceptor Flavor Tabs for puppies (brown box/ for 2-10 lbs). I want to buy more for the coming months but I can't seem to find one for puppies. ??

Asked by: Rita
The puppy and adult Interceptor are the same medication and is dosed by weight. Since your puppy is still growing, purchasing a 6 month supply at her current weight might not be the most economical since she may outgrow a smaller size before the 6 months is finished. Our veterinarian recommends purchasing one month at a time based upon the weight until an adult weight is reached. Many veterinarians sell heartworm prevention in a single dose versus having to purchase 6 months on-line. Check with your veterinarian at your puppy's next visit, which should be a month after the last visit/last vaccination date (they need boosters every 3-4 weeks until they are 4 months old).

My dog is between 8 lbs and 8.5 lbs. Which product by weight is best.

Asked by: Jazzy
You should use the Interceptor for 2-10 pounds to prevent heartworms and deworm for hookworms, roundworms and tapeworms. If you want to add flea control, using Trifexis 5-10 pound would be your best product, IMO.

We are going from Ontario to Florida for 2 weeks. Our dog was on Interceptor over the summer but not since, our vet recommend one dose of Interceptor - when is the best time to give it? Her bloodiest is negative for heartworm. Thanks.

Asked by: Joanne
Since all heartworm preventatives kill the larval stages acquired during the past month, I recommend that you give your dog the Interceptor table during the first week after you get back home from your trip.

If a cat has heart worms can u use this product

Asked by: Cyndi
Interceptor is not approved for use on heartworm positive dogs and cats. However, you can use either Revolution or Advantage Multi as both of those products are approved and safe for use in pets with active heartworm disease.

I used interceptor for my yellow lab puppy when he was picked up for the breeder at 6 weeks old and again at 9 weeks as recommended by the vet. He has now had diarrhea for a full week, is there anything you can suggest?

Asked by: Samm
Interceptor is a very safe product but there is always a chance your puppy can not tolerate it well. To be certain something else isn't causing the diarrhea, such as a food intolerance, eating something from the garbage or picked up outside, or even certain diseases, a trip to your vet is definitely in order.
