What is Sentinel?

Sentinel is the only monthly oral preventive that guards against heartworms, adult roundworms, adult hookworms, whipworms, and prevents the development of flea eggs. Sentinel requires a prescription from your veterinarian.

NOTE: Sentinel does not kill adult fleas. If you see fleas on your pet, use Capstar Flea Treatment Tablets to quickly kill adult fleas within 30 minutes of administration.

For:

Dogs and Puppies (4+ weeks of age, weighing 2+ lbs)

Benefits:

  • Comes in palatable flavored tabs
  • Easy to administer just once a month

How does Sentinel work?

Milbemycin oxime eliminates the tissue stage of heartworm larvae and the adult stage of hookworm, roundworm, and whipworm infestations. Lufenuron, the other active ingredient, is an insect development inhibitor that breaks the flea life cycle by inhibiting egg development. Lufenuron prevents most flea eggs from hatching or maturing into adults and thus prevents and controls flea populations by breaking the life cycle. Sentinel may be given along with Capstar Flea Treatment Tablets, which treats flea infestation and kills adult fleas.

Cautions:

Side effects are rare, though some pets may exhibit vomiting, depression, drowsiness, itching, hives, loss of appetite, diarrhea, or seizures, hypersalivation, and weakness. If these or other symptoms develop contact your veterinarian. It's important to maintain good personal hygiene, since humans can contract hookworms and roundworms. It's also important to eliminate fleas and to not feed your pet rodents or uncooked meat or fish. To prevent re-infection, clean up stools on a daily basis. Consult your veterinarian for pregnant or lactating dogs.

Brand Name:

Sentinel (Virbac)

Generic Name:

Milbemycin Oxime (mil-beh-my-sin ox-eem) and Lufenuron (lew-fen-your-on)

What is the most important information I should know about Sentinel?

Sentinel is a prescription medication FDA-approved for use in dogs. Sentinel is available as artificial beef flavored (derived from pork and soy protein) chewable tablets. This medication should be given once a month year-round.

What should I discuss with my veterinarian before giving Sentinel to my pet?

Tell your veterinarian if your pet has ever had an allergic reaction to the medication.

How should Sentinel be given?

Give Sentinel exactly as directed by your veterinarian. If you do not understand the directions ask your pharmacist or veterinarian to explain them to you. The usual dose of Sentinel for dogs 2 to 10 pounds is 1 Flavor Tab every month (Brown Box), 11 to 25 pounds is 1 Flavor Tab every month (Green Box), 26 to 50 pounds is 1 Flavor Tab every month (Yellow Box) and 51 to 100 pounds is 1 Flavor Tab every month (White Box). For dogs over 100 pounds give the appropriate combination of tablets. To ensure adequate absorption, always administer Sentinel to dogs immediately after or in conjunction with a normal meal. Heartworm testing should be performed prior to the start of prevention therapy. If your pet is off Sentinel for 6 months or less, re-start the medication and test after 6 months since microfilaria, that take 6 months to mature, will result in a positive test result. Store Sentinel in a dry place at controlled room temperature, between 59-77F (15-25 C). Do not remove the tablet from its wrapper until ready to give the medicine. Keep this medication away from children and pets. Consult your veterinarian for pregnant or lactating dogs.

What are the possible side effects of Sentinel?

Side effects of Sentinel are rare although some pets may exhibit vomiting, depression, drowsiness, itching, hives, loss of appetite, diarrhea, or seizures, hypersalivation, and weakness. If these or other symptoms develop contact your veterinarian.

What happens if I miss giving a dose of Sentinel?

If a dose is missed and a 30-day interval between dosing is exceeded, administer Sentinel immediately and resume the monthly dosing schedule. If Sentinel replaces daily diethylcarbamazine (DEC) for heartworm prevention, the first dose must be given within 30 days after the last dose of DEC.

What happens if I overdose my pet on Sentinel?

Contact your veterinarian immediately.

What should I avoid while giving Sentinel to my pet?

Because humans can contract hookworms and roundworms from pets, it is important to maintain good personal hygiene. It is also important to eliminate fleas on your pet and in the household.

What other drugs will affect Sentinel?

While Sentinel is safe to use in dogs at risk for MDRI-allele mutation (Australian Shepherds, Collies, Shelties, etc.), unless tested normal, caution is advised if your pet is also being given amiodarone (Cordarone), azole antifungals such as ketoconazole, carvedilol (Coreg), cyclosporine (Atopica), diltiazem (Cardizem), erythromycin (Ery-Tabs) or clarithromycin (Biaxin), quinidine, spironolactone (Aldactone), tamoxifen, and verapamil (Calan). Do not give Sentinel to your pet if already giving an alternate heartworm medication.

How to Use
Directions:
  • Give Sentinel Flavor Tabs once a month on the same day of each month year-round.
  • Sentinel Flavor Tabs is for use in dogs only. Do not give to cats.
  • Watch your dog closely following dosing to be sure the entire dose has been swallowed. If it is not completely swallowed, give one more full recommended dose as soon as possible.
  • To ensure adequate absorption, always administer Sentinel to dogs immediately after or in conjunction with a normal meal.
  • Sentinel has no effect on adult fleas, but controls flea populations by breaking the flea life cycle at the egg stage.
  • To speed control of flea infestation, products that kill adult fleas like Capstar Flea Treatment Tablets may be used temporarily with Sentinel depending on the severity of the infestation.
  • Treatment may begin at any time of the year.
  • It is important to treat all dogs in the household for fleas. Cats in the same household should be treated with approved products for heartworm prevention for cats.
Tip:

Do not remove Sentinel from its wrapper until ready to give to your pet.

Our dog took her Sentinel, then her sister's dose too. Is this double dose something to worry about? 

Asked by: Divinationjones
No. Sentinel as been tested at much higher doses give daily with no ill effects. You dog may be a little nauseous but that should pass.

I've always given my dog Comfortis for fleas and Heartgard for worms will switching to this product be okay for my dog?

Asked by: Md93
Yes, but the flea control will be different. Instead of killing fleas with the Comfortis, you will instead be sterilizing any fleas so they can not reproduce. The fleas will still live their 2 week life cycle and bite your dog during those 2 weeks.

If given monthly should I still continue to worm my dogs on top of it or will this take care of it?

Asked by: Aimee1
Your dog will be dewormed every month and in most cases, that should be okay. However, if you have a problem with some intestinal parasites, most often hookworms, treating at week 2 with another dewormer may be necessary.

Since my maltese is so picky and I never know what she will eat can I crush and bake in a cookie? 

Asked by: Lydia
I do not recommend that you bake the tablet as the heat may affect the medication. You can still crush the tablet and mix it in something yummy. I recommend liverwurst as it has a strong flavor and odor to cover the medication and most dogs love it. Making several little balls to give, with just one that has the medication in it, works well. You give 1-2 without the medication to get your dog excited about eating them, then the one with it, and finishing with one without so that is how the dog will remember the special treats.

Asked by: EAD21
Sentinel does not protect your pet against ticks. If you are looking for something that protects against fleas, ticks, and heartworm, you may want to look into Revolution. If you are going to use Sentinel, you should not use any other heartworm preventative with it. However, your pet will not be protected from ticks.

Can you cut a tablet for a hundred pound dog in half and give it to a 50 pound dog

Asked by: Grace
It is not recommend to cut a tablet in half for your smaller dog. It is difficult to ensure you are giving exactly half of the tablet, and may end up giving more or less of the dose and over- or under-medicating you dog. This can lead to added side effects and toxicities, or decreased effectiveness of the medication in the event of under-dosing.
