Sentinel Flavor Tabs Basics

Sentinel Flavor Tabs are used to treat parasites in dogs. They are used to control fleas, heartworms, roundworms, hookworms, and whipworms. These tablets contain two chemicals: lufenuron and milbemycin oxime. Lufenuron inhibits flea development within the egg, which prevents fleas from ever maturing to adulthood. Milbemycin oxime acts by disrupting nerve transmission within the flea leading to death.

Sentinel Flavor Tabs require a prescription from your veterinarian. Tabs come in a palatable flavor that is administered once each month.

Sentinel Flavor Tabs Directions

Use as directed by your veterinarian, and always follow the instructions on the prescription label. Store at room temperature, protected from light and moisture. Administer once each month. Dosage is based on your dog’s weight.
