Interceptor Flavor Tabs are indicated for use in the prevention of heartworm disease caused by Dirofilaria immitis, the control of adultAncylostoma caninum (hookworm), and the removal and control of adult Toxocara canis and Toxascaris leonina (roundworms) and Trichuris vulpis(whipworm) infections in dogs and in puppies four weeks of age or greater and two pounds body weight or greater.
Interceptor Flavor Tabs for Cats are indicated for use in the prevention of heartworm disease caused by Dirofilaria immitis, and the removal of adult Ancylostoma tubaeforme (hookworm) and Toxocara cati (roundworm) in cats and kittens six weeks of age or greater and 1.5 lb. body weight or greater.

Palatability trials conducted in 244 dogs from 10 different U.S. veterinary practices demonstrated that INTERCEPTOR Flavor Tabs were willingly accepted from the owner by over 95% of dogs. The trial was comprised of dogs representing 60 different breeds and both sexes, with weights ranging from 2.1 lb. to 143.3 lb., and ages ranging from 8 weeks to 15 years.

Interceptor Flavor Tabs eliminate the tissue stage of heartworm larvae and the adult stage of hookworm (Ancylostoma caninum),roundworms (Toxocara canis, Toxascaris leonina) and whipworm (Trichuris vulpis) infestations when administered orally according to the recommended dosage schedule. The anthelmintic activity of milbemycin oxime is believed to be a result of interference with invertebrate neurotransmission.

Potential Side Effects:
A mild, transient hypersensitivity reaction (labored breathing, vomiting, salivation and lethargy) has been noted in some dogs carrying a large number of circulating microfilariae (immature heartworm). These reactions are likely due to the parasites dying all at once.
May also cause itchiness, hives and red skin, lethargy, depression, staggering, convulsions, weakness.
More serious side effects could occur in a dog with preexisting heartworm infection.
If you notice anything unusual, contact your veterinarian.

Adverse Reactions:
The following adverse reactions have been reported following the use of INTERCEPTOR Flavor Tabs: pression/lethargy, vomiting, ataxia, anorexia, diarrhea, convulsions, weakness and hypersalivation.

Do not use in puppies less than four weeks of age or less than two pounds of body weight. Prior to initiation of the interceptor Flavor Tabs treatment program, dogs should be tested for existing heartworm infections. Infected dogs should be treated to remove adult heartworms and microfilariae prior to initiating treatment with interceptor Flavor Tabs. Mild, transient hypersensitivity reactions manifested as labored respiration, vomiting, salivation and lethargy, have been noted in some treated dogs carrying a high number of circulating microfilariae. These reactions are presumably caused by release of protein from dead or dying microfilariae.

Federal (USA) law restricts this drug to use by or on the order of a licensed veterinarian.
Keep this and all drugs out of the reach of children.

Interceptor flavor tabs should be stored at room temperature, between 59° and 77°F (15-25°C).
