Overview

View our How to manage Heartworms video.

What is Sentinel?
Sentinel Flavor Tabs kill the immature form of the heartworm (Dirofilaria immitis). They also control adult hookworms (Ancylostoma caninum), and remove and control roundworms (ascarids - Toxocara canis and Toxascaris leonina) and whipworms (Trichuris vulpis). In addition, Sentinel Flavor Tabs break the flea life cycle.

Who is it for?
For dogs and puppies over 4 weeks of age weighing more than 2 pounds. Safe to use in pregnant and nursing dogs.

What are the benefits?

*
Protects your dog against heartworm disease and intestinal worms
*
Easy to administer tablet also helps control fleas
*
Palatable beef-flavored tablets taste like treats

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?
No.

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.

What form(s) does it come in?
Tablets

What should I discuss with my veterinarian while considering Sentinel?
Talk to your veterinarian about the heartworm testing that is recommended before starting your dog on a heartworm prevention program.

Some intestinal parasites, such as hookworms and roundworms can be spread to people. Talk to your veterinarian about other measures you can take to prevent your pet from being infected with intestinal worms, and protecting yourself.

Notify your veterinarian of any other medications or supplements your dog is taking, and also if your dog has had any reactions to previous medications.

What should I do if I miss a dose?
If a dose is missed and over 30 days have gone by since the last dose, give Sentinel immediately and resume the monthly dosing schedule. Tell your veterinarian that a dose was missed.

What is the most important information I should know?
If the interval between doses is longer than one month, the efficacy of the drug is reduced.

Q. 
Q. 
Q. 
 What is Sentinel?
A. 
Sentinel is a tablet containing a mixture of lutenuron and milbemycin oxime that protects your dog from heartworm, hookworm, whipworm, and roundworm and helps control fleas. Sentinel is the only product that controls five different kinds of parasites and leaves no pesticide residue.


Are there side effects from Sentinel?
A. 
Sentinel is safe for your pet when used correctly. Do not use on dogs with pre-existing heartworm infestations and high numbers of circulating microfilariae (juvenile stage), because they may experience shock-like reactions.  


 If my pet is on a different heartworm preventative, how do I change to Sentinel?
A. 
If Sentinel replaces daily dosing heartworm tablets containing DEC (Diethyl-Carbamazine Citrate), like Filaribits, the first dose must be given within 30 days of the changeover. If Sentinel replaces other monthly heartworm treatment, like Heartguard, simply continue your monthly dosing regime.


How do I give Sentinel to my Pet?
A. 
The Sentinel tablets should be given to your pet once a month, preferably on the same day of each month. Sentinel can be given directly or hidden in your pet's food, since the tablets should be given with a full meal or immediately afterwards.


 What happens if I miss a tablet?
A. 
If you miss the 30-day interval by less than seven days, administer Sentinel immediately and resume your monthly dosing schedule. If the interval is longer than seven days consult your veterinarian.


 Can I use Sentinel year round?
A. 
Yes. Sentinel is safe to use year round for protection from heartworm, roundworm, whipworms, hookworms, and for flea control.


 Can I use Sentinel on puppies?
A. 
Yes. Sentinel is safe for use in puppies over 4 weeks of age. Sentinel has been approved by the FDA and has been tested for safety on over 40 breeds of dogs.


Does Sentinel kill fleas?
A. 
Sentinel does not kill adult fleas; Sentinel contains lufenuron, which inhibits flea egg development. For best results treat your pet with a product designed to kill adult fleas before Sentinel is administered. This will help reduce the flea population.  


 Does Sentinel kill ticks?
A. 
Although Sentinel stops development of flea eggs, it is not labeled to prevent your pet from getting ticks. It is important to use a tick preventative while your pet is on Sentinel.
