What is Sentinel Spectrum?

Simplify your dog's heartworm and flea protection with Sentinel Spectrum, the only beef-flavored chewable to protect against 6 parasites. Given monthly, Sentinel Spectrum prevents heartworms and prevents and controls fleas. Each chew also treats and controls whipworms, hookworms, roundworms and tapeworms. Sentinel Spectrum requires a prescription from your veterinarian.

For:

Dogs & Puppies (6+ weeks of age, weighing 2+ lbs)

Benefits:

  • Dogs love the delicious beef-flavored chewable
  • Prevents heartworms
  • Prevents and controls fleas
  • Treats and controls common intestinal parasites (whipworms, hookworms, roundworms and tapeworms)
  • Simple once-a-month administration
  • No messy residue to worry about, unlike spot-on treatments

How does Sentinel Spectrum work?

Milbemycin oxime, lufenuron, and praziquantel are the active ingredients in Sentinel Spectrum, which work to control fleas, major intestinal worms, and heartworms. Sentinel Spectrum contains an insect growth regulator (IGR), which kills flea eggs thus preventing them from hatching into adult fleas. Sentinel may be given along with Capstar, which treats flea infestation.

Cautions:

Mild, transient hypersensitivity reactions, such as labored breathing, vomiting, hypersalivation, and lethargy, have been noted in some dogs treated with milbemycin oxime carrying a high number of circulating offspring (microfilariae). These reactions are presumably caused by the release of protein from dead or dying offspring. Do not use in puppies less than six weeks of age. Do not use in dogs or puppies weighing under two pounds. The safety of Sentinel Spectrum has not been evaluated in dogs used for breeding or in lactating females.

Brand Name:

Sentinel Spectrum

What is the most important thing I should know about Sentinel Spectrum?

Sentinel Spectrum is indicated for the prevention of heartworm disease caused by Dirofilaria immitis, for the prevention and control of flea populations, and for the treatment and control of adult roundworm, adult hookworm, adult whipworm, and adult tapeworm infections in dogs and puppies two pounds of body weight or greater and six weeks of age and older. The active ingredients are Milbemycin oxime, lufenuron, and praziquantel.

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

Sentinel Spectrum requires a prescription from your veterinarian. Ask your veterinarian if Sentinel Spectrum is right for your pet. Treatment with fewer than 6 monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration of Sentinel Spectrum, dogs should be tested for existing heartworm infections. At the discretion of the veterinarian, infected dogs should be treated to remove adult heartworms. Sentinel Spectrum is not effective against adult D. immitis.

How should Sentinel Spectrum be given?

Sentinel Spectrum should be administered orally, once every month with dosing based on your dog's weight. For heartworm prevention, give once monthly for at least 6 months after exposure to mosquitoes. Sentinel Spectrum should be given once a month, every month of the year. Preferably, Sentinel Spectrum should be given on the same date each month. For dogs and puppies 2-8 lbs, give 1 chewable every month (Orange box). For dogs 8.1-25 lbs, give 1 chewable every month (Green box). For dogs 25.1-50 lbs, give 1 chewable every month (Yellow box). For dogs 50.1-100 lbs lbs, give 1 chewable every month (Blue box). For dogs over 100 lbs, give the appropriate combination of chewables.

To ensure complete absorption, always give Sentinel Spectrum chewables to dogs either with or immediately after a normal meal. Food is essential for proper absorption of the product into the bloodstream. Most dogs like the taste of the Sentinel Spectrum chewable and will accept the chewable readily as a treat. The chewables should be administered in a manner that encourages the dog to chew, rather than to swallow the medication without chewing. The chewables may be broken into pieces and fed to dogs that normally swallow treats whole.

Sentinel Spectrum should be administered at monthly intervals beginning within 1 month of the dogs first seasonal exposure to mosquitoes and continuing until at least 6 months after the dogs last seasonal exposure. Sentinel Spectrum may be administered year-round without interruption. When switching from another heartworm preventative product to Sentinel Spectrum, the first dose of Sentinel Spectrum should be given within a month of the last dose of the former product.

What are the potential side effects of Sentinel Spectrum?

The following adverse reactions have been reported in dogs after administration of milbemycin oxime, lufenuron, or praziquantel: vomiting, depression/lethargy, pruritus, urticaria, diarrhea, anorexia, skin congestion, ataxia, convulsions, salivation, and weakness.

What happens if I miss giving a dose of Sentinel Spectrum?

Consult your veterinarian.

What happens if I overdose my pet on Sentinel Spectrum?

Consult your veterinarian in the event of a suspected overdose of Sentinel Spectrum.

What should I avoid while giving Sentinel Spectrum to my pet?

Do not give Sentinel Spectrum to your pet if already giving an alternate heartworm medication.

What other drugs will affect Sentinel Spectrum?

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).

How to Use

Sentinel Spectrum Directions:

  • Give Sentinel Spectrum once a month on the same day of each month year-round.
  • For proper digestion, administer Sentinel Spectrum to your dog immediately after or with a normal meal.
  • Sentinel Spectrum 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.

Customer Reviews
Sentinel Spectrum is rated 4.4 out of 5 by 66.
Rated 5 out of 5 by from All in One! I love the idea of an "all in one" medication. No more oily residue with topical flea/tick treatments. I live in Florida and fleas and ticks can be a problem year round. And you cannot beat the customer service with 1800PetMeds!

Rated 5 out of 5 by from 16# Lucky has been on Sentinel Spectum for over a year with great results. He is picky but he eats this.

Rated 5 out of 5 by from ONLY Heartworm preventative that helps! We welcomed my Black Lab rescue in June of 16 and he came to us with heartworms, it was a big struggle because the eggs were staying in his system. My awesome Vet worked directly with a Vet at the American Heartworm Assoc., and combined with other treatment this helped! Going forward this was the recommended brand to use and keep my Lab healthy and I'll never use another.
