Interceptor Intestinal Worm & Heartworm Tablets for Dogs

Interceptor is an oral treatment that prevents heartworm disease. The flavored tab controls adult hookworms and removes and controls adult roundworm and whipworm infections in dogs and puppies. It kills the immature heartworms the pet may be exposed to in the previous month. The monthly tablet treats and prevents hookworms and roundworms in dogs. The tasty beef-flavored tab is easy to administer and safe for dogs.

Suitable to use in pregnant and nursing dogs, Interceptor is safe for dogs and puppies over 4 weeks of age.

How Interceptor Works?

Interceptor contains milbemycin oxime, a highly anti-parasitic ingredient. It interferes with the parasite's nerve transmission, causing the death of immature heartworms and adult intestinal worms. It eliminates the adult stage of hookworm, roundworm, and whipworms in dogs. It prevents heartworm infection and treats and controls worm infection in puppies and dogs.

Ingredients: Milbemycin, Praziquantel

Get your pet tested by a veterinarian before starting the treatment. Weigh your dog before the treatment to choose the correct Interceptor tablet. Give the tablet periodically at every month, preferably on the same date. Maintain a treatment chart and keep the record of your pet’s heartworm treatment.

Very easy to administer, this palatable tablet can be given either by mouth or mixed with the dog’s food. Most of the dogs just find it a treat and enjoy chewing it. Make sure the dog consumes entire dosage by monitoring your pet. 

Puppies need to be treated with Interceptor Spectrum at 2, 4, 8, 12 weeks of age. Repeat every month after this.

Adult dogs need to be given a monthly dosage as per their weight. Maintaining the same date is always advisable and a sign of proper treatment.

Pregnant bitches need to be given the tablets at mating time, prior to whelping and then monthly.

Please get your animal tested for heartworm infection before starting the treatment. A transient shock like reaction occurs in dogs infected with adult heartworms. Thus, testing and treating the dog for such infection is a must before starting Interceptor spectrum treatment.

Though it is highly safe still contact a vet if you find any unusual signs after administering the tablet.
