INTERCEPTOR PLUS is indicated for the prevention of heartworm disease caused by Dirofilaria immitis; and for the treatment and control of adult roundworm (Toxocara canis, Toxascaris leonina), adult hookworm (Ancylostoma caninum), adult whipworm (Trichuris vulpis), and adult tapeworm (Taenia pisiformis, Echinococcus multilocularis and Echinococcus granulosus) infections in dogs and puppies two pounds of body weight or greater and six weeks of age and older.

Prescription Required


Milbemycin Oxime


INTERCEPTOR PLUS should be administered orally, once every month, at the minimum dosage of 0.23 mg/lb (0.5 mg/kg) milbemycin oxime, and 2.28 mg/lb (5 mg/kg) praziquantel. For heartworm prevention, give once monthly for at least 6 months after exposure to mosquitoes

View Interceptor Plus Drug Facts Sheet.

Dosage Schedule
Body Weight Milbemycin Oxime per chewable Praziquantel per chewable Number of chewables
2 to 8 lbs 2.3 mg 22.8 mg 1
8.1 to 25 lbs 5.75 mg 57 mg 1
25.1 to 50 lbs 11.5 mg 114 mg 1
50.1 to 100 lbs 23 mg 228 mg 1
Over 100 lbs Administer the appropriate combination of chewables.

INTERCEPTOR PLUS may be offered to the dog by hand or added to a small amount of dog food. The chewable should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that no part of the dose is lost or rejected. If it is suspected that any of the doses have been lost, redosing is recommended.

Heartworm Prevention:

INTERCEPTOR PLUS should be administered at monthly intervals beginning within 1 month of the dog's first seasonal exposure to mosquitoes and continuing until at least 6 months after the dog's last seasonal exposure. INTERCEPTOR PLUS may be administered year-round without interruption. When switching from another heartworm preventative product to INTERCEPTOR PLUS, the first dose of INTERCEPTOR PLUS should be given within a month of the last dose of the former product.

Intestinal Nematode and Cestode Treatment and Control: Dogs may be exposed to and can become infected with roundworms, whipworms, hookworms, and tapeworms throughout the year, regardless of season or climate. Clients should be advised of appropriate measures to prevent reinfection of their dog with intestinal parasites. Because the prepatent period for E. multilocularis may be as short as 26 days, dogs treated at the labeled monthly intervals may become reinfected and shed eggs between treatments.

Although these chews, prescribed by our vet to guard against fleas and heartworm, are not her favorite thing to eat, Missy does eat them.
Merchant Response:Suzie, They say an ounce of prevention is worth a pound of cure. Glad to hear Missy takes her Interceptor Plus medicine. You both take care!

I have 2 small dogs and they both take this. We have no issues and both dogs chew it up and swallow it quickly. Never had any trouble with it bit staying down or the dogs acting like they don't feel well with this.
Merchant Response:Hi Chris, Great to hear that Interceptor Plus Green is working well for both your dogs. Hope all is well!

Buying heart worm meds online was easy, cheaper than buying them from a veterinary practice, and quick. Communication from Entirely Pets Pharmacy was terrific.
ConsThank you for the great feedback Lee! Glad to hear the Interceptor works well for your dog and we were able to save you some money and the hassel at the same time!
