How does Sentinel work?
Sentinel is used in the prevention, control, and treatment of various worm infections. Sentinel Flavor Tabs contain milbemycin oxime, which interferes with the worms nervous system, eliminating the immature stage of the heartworm larvae and the adult stage of hookworms, roundworms and whipworms. Sentinel also contains lufenuron, an insect development inhibitor, which breaks the flea life cycle by inhibiting flea egg development.
Is there a generic equivalent available?
How is it given?
Sentinel must be administered monthly, preferably on the same date each month. Drs. Foster and Smith recommends (and our guarantee requires) that Sentinal be given year round, although some veterinarians may recommend giving it only during the mosquito season. If given seasonally, the first dose must be given within 30 days of the dog's first exposure to mosquitoes. The last dose must be given within 30 days after the dog's last exposure to mosquitoes.
To ensure complete absorption, always give Sentinel Flavor Tabs to dogs either with or immediately after a normal meal. Food is essential for proper absorption of lufenuron into the bloodstream.
Most dogs like the taste of Sentinel Flavor Tabs and will accept the tablet as a treat. As an alternative to a treat, they may be offered in food or given to your dog as you would other tablet medications. With either method of administration, the dog should also eat a whole meal. Watch the dog closely to be sure the entire dose has been consumed. If not entirely consumed, give another full recommended dose as soon as possible.
What results can I expect?
Sentinel will kill the immature heartworms the dog was exposed to in the preceding month. It will treat an intestinal infection with adult hookworms and roundworms. It will not kill adult fleas, but will prevent flea eggs from maturing.
