Rated 5 out of 5 by from Good Preventive My dog was treated for heartworms about 8 years ago, after I got her, and I have had her on Sentinel Spectrum ever since. She is an outside dog with her own doghouse, heater, barn, large yard etc :) She has always tested negative for heartworms since she was treated and I also never find fleas or ticks on her. I have been really satisfied with this product!

Rated 1 out of 5 by from Does not kill fleas This product does not kill fleas. It supposedly prevents flea eggs from hatching, but does nothing about the existing flea population. We gave our newly adopted dog this product fpr 6 months and he has consistently had fleas which has led to constant scratching, dry skin, and hot spots. I'm sure it's protection against other parasites are good, but something as simple as fleas needs to be killed, not just "prevented".

Rated 5 out of 5 by from this is saving my dogs from pests in Hawaii Dogs needed to be on full protection of anti flea and anti worm meds. In Hawaii, new research is showing that the menangitis causing rat lung worm disease in slugs and in the worms, etc. is prevented in dogs on medications like Sentinel spectrum. My dogs have never had side effects and take the chewables with ease. Pevent sudden death or paralysis from rat lung worm in your dog with Sentinel Spectrum, while preventing fleas.

Rated 4 out of 5 by from Does not kill existing fleas on dog I love Sentinel Spectrum. I have used this product for a couple of years with no problems. In the past couple of months I have noticed that one of my dogs is scratching and licking almost 24-7. I found several fleas on him. I asked my vet about this and he said that the Sentinel Spectrum sterilizes the fleas but does not kill any existing fleas found on the pet. Now I do not know what to do as this product is the only one I have used that does not make my dog sick and it works for controlling flea population and heartworm prevention. Can I use a product like Capstar to kill any existing fleas while using the Sentinel Spectrum? Right now, my dog is in a ball biting himself to death.

Rated 1 out of 5 by from Didn't work, dog wouldn't eat it Received this two weeks ago. It comes in a convenient, tasty smelling chew. Unfortunately dog refused to eat it. I divided it into tiny pieces and force fed it to her. I also treated her with two doses of Capstar, since Sentinel Spectrum doesnt kill live fleas. Two weeks later, she still has fleas. It's pretty much useless to me.

Rated 5 out of 5 by from I have 2 dogs, a large Pit Mix and small Yorkie, I have been using sentinel spectrum for over a year now and have had zero issues. My dogs think they are treats so never have difficulty giving to them. Before we started this product we were having a major problem with fleas. Nothing we tried worked. We had just moved to a new home and suddenly our dogs and home were infested with fleas after a couple months living here. After 2 months of having them on this heartworm and flea pill we have not had any more problems with fleas. I highly recommend this product!!

Rated 1 out of 5 by from Wasted my money I bought this for my bully mixes hoping it was comparable to Revolution. They have never had fleas. Until now. I gave them both 2 doses in a 3 week period followed by flea baths and my female has scratched and chewed herself raw because she's miserable. We switched to the all on one chewables but only Revolution has worked.

Rated 4 out of 5 by from Works great I would not buy any other type of HW treatment at all. I just wish they tasted better for my baby. I have to grind it in a powder to put it in his food. He will not eat it alone at all. Evidently it is not a yummy delicious treat like I have seen advertised. If this came in a liquid form, I would even be willing to try that. But as far as it working and doing the trick. There is nothing better out there.

My vet has prescribed NexGard and Sentinal Spectrum together for my Bichon Friese who weighs 15 lbs. Both apparently kill flees, so why would I need both?

Asked by: Dolly
Nexgard and Sentinel Spectrum work differently killing adult fleas and eggs, respectively. Afoxolaner, the ingredient in NexGard Chewables, works by absorbing rapidly and safely into your pet's bloodstream and causes uncontrolled activity the fleas' and ticks' central nervous systems, which causes death. Sentinel Spectrum contains an insect growth regulator (IGR), which kills flea eggs thus preventing them from hatching into adult fleas.

Will it hurt my dogs to give sentinel spectrum this medication when it expired 08/2018?

Asked by: Sandi th
the expiration date is when the medication starts to loose it's potency, most drugs are still fine for a year. then they are a lower dose. this is most medications. if it stays in refrigerator or something obvious like that, they are the type that degrade very quickly, like insulin. pills kept in cool dry places, medicine cabinet are good for a while, now you will not find an answer about when you should discard. they want for you to buy more. most expirations and sell by dates in the USA have nothing to do with if the product is bad. its liability and profit. Ancient Himalayan pink salt, how can it have an expiration, its already ancient! honey last forever. don't drink the clumpy milk!!!! just use your own common sense.

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, 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).

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.
Tip:

Do not remove Sentinel Spectrum from the wrapper until ready to give to your dog.

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.

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, 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).

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.
