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.

How to Use

Interceptor 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 572.
Rated 5 out of 5 by from Essential Med In south GA we have mosquitos with their heartworm larvae threat all 12 months. Since 1993 I have kenneled 11 labs in my outside kennel and Interceptor has provided complete protection for my dogs. I even ordered it from Australia while it temporarly stopped sales in the US. The best field trial judging gift I ever received was several packs of Interceptor ! Use as directed and you will not let your dogs down with a case of heartworms plus you get the added protection from whipworms.

Rated 5 out of 5 by from Love the Inteceptor! We live in the country and our dogs are all over the place! One is an Airedale Terrier and eats everything she kills. She constantly had worms so we switched to Interceptor and she has been worm free ever since!

Rated 1 out of 5 by from Bad Moved from the country, where my Lab was an outside dog to the city where he became an inside dog. Changed vets, took him in and he had round worms. The vet suggested Interceptor to prevent both heart and round worm. I changed him at age 6 to interceptor. He just turned 7 had his vet visit and now he tested positive for heart worm. Obviously Interceptor doesn't work!

Rated 5 out of 5 by from Great I have four fur babies and they all have been on Interceptor their whole lives, except for the short time it was not available. Two are 15 yo. So no problems. This is a great product.

Rated 5 out of 5 by from Other brands made my dog sick, but this is great! My vet recommended another heartworm medicine that made my dog very ill - vomitting and lethargy. I was very concerned to try another brand, but my dog has had no problems with this Interceptor at all and he will even eat the pill on his own - it is flavored - without me having to hide it in food, which is crazy, because he is very leary of pills. The most important part is, it doesn't make him sick.

Rated 5 out of 5 by from Very Pleased! I've used this product on all my dogs, since they were puppies. I've always been pleased with it, and would highly recommend it.

Rated 5 out of 5 by from So much better than Trifexis I was hesitant to change my Australian Shepherd's meds from Trifexis to anything else considering the possibility of issues with reactions to meds whether or not he has the gene mutation was unknown. When we got Pirate in 2013, interceptor was not available in the market whatsoever so we started off with Trifexis. We always struggled with vomiting after he took it and tried different times of the day (with a meal, hour after, etc) to no avail. I didn't want to make him sick anymore and to be honest, he didn't suffer from fleas anyway even though we are in Florida... We treat our lawns for that. I decided to look online for alternatives and noticed interceptor was available again and the name sounded familiar from his paperwork when we got him. I gave it to him without any issue, no vomiting, no lethargy. I couldn't be happier for us and him. Thanks for coming back on the market, I am never going back!

Rated 5 out of 5 by from Good little pill We have used this medication for as long as it has been available with great results. She passes her test every year so it must be working, with no side effects.

Q&A

Can I use interceptor with Bayer quad dewormer?

Asked by: Tina1969
Thank you for your question. It is not recommended to use two dewormers at the same time. Interceptor works to treat hookworm, roundworm, and whipworm. Bayer Quad works to prevent hookworm, roundworm, whipworm, and tapeworm. Your veterinarian should test your pet to determine which worms they are infected with and help you choose the best medication to treat your pet.

I can/t find expiration dates of Interceptor online. the phone contact says "usually in one year to 16 months". In the past, not necessarily with PetMeds, I've had some problems with 6 month expiration dates. Ideas on how to find out???

What is the difference between interceptor and interceptor plus? My vet was prescribing interceptor plus but I don't see this medication on here.

Asked by: Britt
Thank you for your question. We offer both the Interceptor and Interceptor Plus. Both products offer the same protection however Interceptor Plus also prevents Tapeworm while Interceptor does not. Also Interceptor is a beef flavored flavored chewable tablet. Interceptor Plus is a chicken flavored chewable tablet, , which is an added benefit for dogs suffering from beef allergies. Here is the link to the Interceptor Plus as you mentioned you could not find the product https://www.1800petmeds.com/Interceptor+Plus-prod11710.html.

My husband accidentally gave the second dose of Interceptor to our dog 2 days after I gave the first one. Would the dog have been overdosed already by just this one time incident? If so, what would be the symptoms of overdose?

Asked by: spicyfood
Thank you for your question. If you believe your pet has overdosed contact your veterinarian immediately. Side effects of Interceptor are rare although some animals may exhibit depression, drowsiness, vomiting, loss of appetite, diarrhea, hyper salivation, seizures and weakness. If these or other symptoms develop contact your veterinarian.

Does my dog really need heart worm pill 

Asked by: Queenb
It is important to protect your pet from heartworm disease which can be potentially life threatening. Fortunately, preventing heartworms is as easy as giving your pet a monthly preventative. Consult your veterinarian for the appropriate choice of preventative for your pet.

Does this medicine also help with fleas and or ticks?

Asked by: Momoney27
No. The Interceptor prevents heartworm disease, controls adult hookworms, and removes and controls adult roundworms and whipworm infections only. Interceptor is not effective against fleas and ticks. Please see the link below to view the Trifexis which kills fleas and prevents infestations, protects against heartworms, and treats and controls adult hookworm, roundworm, and whipworm infections.
