Lufenuron and Milbemycin (Sentinel Flavor Tabs®)
By: Dr. Dawn Ruben

Overview

Parasitic infections are common in dogs and include both external parasites (fleas, ticks, mites), and internal parasites (intestinal worms, lungworms and heartworms).

Control of insect parasites, such as fleas, can be achieved by a number of approaches. One of the most novel methods is the use of insect growth regulators. These drugs arrest the development of insect parasites yet demonstrate great safety when administered to animals.

Lufenuron belongs to a class of drugs known as insect development inhibitors/insect growth regulators.

Lufenuron inhibits insect development within the insect egg. This prevents the egg from maturing to an adult insect.

Lufenuron is most commonly administered for flea control in dogs and in cats. It does not control ticks.

Dogs and cats already affected with fleas, or those with flea-allergy dermatitis, first should be treated with an insecticide approved for that species.

Lufenuron is available by veterinary prescription as a single drug (Program®) for dogs and for cats. It has also been combined with the drug milbemycin oxime into a single pill (Sentinel Flavor Tabs®) to provide broad spectrum control of parasites.

Milbemycin oxime is a parasite control drug effective in controlling or preventing several of the most common parasitic diseases of dogs.

Milbemycin oxime is approved by the Food and Drug Administration to control hookworm, roundworm and certain whipworm infections and to prevent heartworm infection in dogs.

The combination of lufenuron and milbemycin oxime (Sentinel Flavor Tabs®) is only approved for use in dogs.

Additional information about the individual drugs is available under lufenuron or milbemycin oxime.

Lufenuron and milbemycin oxime is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
