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.

Rated 5 out of 5 by from Interceptor is the only product I will use!~ The main reason why i love Interceptor is b/c it covers the Whip worm, which most products don't.. Since my babies have been on this stuff for over 9 years this is teh only product I will continue you to use.

Rated 5 out of 5 by from So glad it's back and for dog and cat! So happy to see Interceptor back and use for dog, as well as cat! I was concerned I wouldn't be successful getting our cat to take a pill, but, no problem, he gulped this one down in a flash! Both our dog (Golden Retriever) and our cat had gotten sick and lethargic from other brands. Also very pleased with the ease in purchasing our pet meds here with super fast service and shipping!

Rated 5 out of 5 by from It Really Works! I have a 6 month old black lab. She recently became infected with whipworms. The heart worm preventative that she was taking was not helping her at all, so the vet prescribed us Interceptor to help fight the whipworms. With in 2 weeks I noticed a difference in her fecal samples I brought to the vet. I recommend Interceptor to anyone who wants complete protection for the dogs from any kind of worms.

Rated 5 out of 5 by from Very happy I was paying a fortune for Trifexis when Penny did not need flea or parasite protection. As an Amish Aussie, she cannot take Heartgard due to the Ivermectin in it so I was thrilled when Interceptor was once again available. Penny is doing very well and takes her meds without any difficulty.

Rated 5 out of 5 by from So glad they went back to the original I was so happy to get notified last year that the flea protection was not in this anymore. My dog already had something for fleas and I didn't want to double dose her. She doesn't like pills so this small pill is easier to make her take.

Rated 5 out of 5 by from Great product First, the product apparently tastes great because my dog eats it's whole by itself! I don't have to hide it in cheese or anything!! Second, my dog has a super super sensitive stomach and this gave him no problems at all :) I've already reccomended it to some friends!

My dog has become extremely picky and will not eat this pill, no matter what food i put it with he spits it out. I know it is supposed to be chewed so is it okay to break it into a few pieces and place it in the back of his throat to make him swallow it?

Asked by: ljholc
Yes, you may break the tablet into pieces and do whatever is necessary to get your dog to swallow it.

My dogs get the sentinel tabs for heartworms and then getting the reg. meds for the other worms. Will this work for all 4 worms and do I still give them both meds?

Asked by: eliz
Sentinel not only prevents heartworms, but also deworms monthly for roundworms, hookworms and whipworms. Any additional dewormings are usually unnecessary unless the dog is reinfecting itself with a heavy load of parasites. The only parasite you may have an issue with is tapeworms, which are carried by fleas. Sentimel sterilizes fleas so they can't reproduce but if your dog swallows an adult flea it picked up anywhere, it may still get tapeworms. Sentinel Spectrum will do the same as Sentinel but also deworms for tapeworms every month.

Asked by: Jodi
Your Yorkie should be fine; however, make sure to monitor them for side effects or changes in behavior and contact your veterinarian right away if you notice anything different. 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.

Difference between Interceptor and Interceptor Plus? Does Interceptor/Interceptor Plus also prevent/treat flea/ticks? If I switch from Heartguard Plus & Nexgard, am I losing any protection?

Asked by: krystaldesigns
Interceptor Plus also protects against tapeworms, while Interceptor does not. You are not losing any protection if you switch from Heartgard to Interceptor Plus. In fact, Interceptor Plus gives you added protection against both whip worms and tapeworms, unlike Heartgard. However, you will still need to use NexGard or another flea and tick preventative since Interceptor Plus does not protect against fleas and ticks.
