Interceptor Flavor Tabs Basics
Interceptor Flavor Tabs are available by prescription only. Interceptor Flavor Tabs are used to control parasite infections in dogs and cats. Interceptor contains milbemycin oxide, a medication used to control some of the most common intestinal parasites and heartworms. Milbemycin oxime works by disrupting nerve transmission within the parasite. Interceptor Flavor Tabs is used to treat heartworms, hookworms, roundworms, certain whipworms and demodectic mange. Interceptor Flavor Tabs are given monthly.

Interceptor Flavor Tabs Warnings

Animals should be tested for heartworm infections before beginning Interceptor treatment. Interceptor should not be used in cats less than 6 weeks of age or those weighing less than 1.5 pounds.
