What is Interceptor (milbemycin oxime)?
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.

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.
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.

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.

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 dogs at a normal dose level. Safety in breeding, pregnant and lactating queens and breeding toms hasn’t been established.
