Sentinel Spectrum is indicated for the prevention of heartworm disease. It is also formulated to help prevent and control flea populations, and for the treatment and control of adult roundworm, hookworm, whipworm, and tapeworm infections in dogs and puppies six weeks of age and older and weighing at least two pounds.
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.
There are no known contraindications to the use of Sentinel Spectrum.
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. This medication is not effective against adult D. immitis. 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 microfilariae. These reactions are presumably caused by release of protein from dead or dying microfilariae. Do not use in puppies less than six weeks of age. Do not use in dogs or puppies less than two pounds of body weight. The safety of this medication has not been evaluated in dogs used for breeding or in lactating females. Studies have been performed with milbemycin oxime and lufenuron alone. Not for use in humans. Keep this and all drugs out of the reach of children.
23 mg Milbemycin Oxime, 460 mg Lufenuron and 228 mg Praziquantel.
Sentinel Spectrum should be administered orally, once every month, at the minimum dosage of 0.23 mg/lb (0.5 mg/kg) milbemycin oxime, 4.55 mg/lb (10 mg/kg) lufenuron, and 2.28 mg/lb (5 mg/kg) praziquantel. For heartworm prevention,ngive once monthly for at least 6 months after exposure to mosquitoes.
Store in a dry place at controlled room temperature between 59° - 77°F.
Not all heartworm medicines provide the same spectrum of parasite protection. Sentinel Flavor Tabs are chewable tablets that protect dogs against fleas, heartworms, roundworms, hookworms, and whipworms. Sentinel Spectrum is a soft, beef and bacon flavored chew that adds tapeworm protection to offer the broadest coverage available.
Yes. Talk to your veterinarian about the appropriate dose for your pet.
Yes. Both Sentinel Specturm and Sentinel Flavor Tabs offer a size that can be given to small dogs. Sentinel Spectrum has a size available for dogs weighing from 2–8 lbs and Sentinel Flavor Tabs has a size available for dogs weighing from 2–10 lbs.
You may see an occasional “hitchhiker” adult flea that your dog has picked up at the dog park or in the yard or other infested environments where 95% of the flea population lives in the form of eggs, maggot-like larvae, and pupae. Sentinel Specturm and Sentinel Flavor Tabs put an end to fleas before they become adults. You may need an adulticide, such as Effitix Topical Solution for Dogs, to treat occasional adult fleas.
No, both Sentinel Spectrum and Sentinel Flavor Tabs are only approved for use in dogs.
I have been using Sentinel Spectrum chews for over a year now per the recommendation of my veterinarian. I got a prescription through Chewy after my dogs hit 50+ pounds. It's wonderful not having to drive back and forth to the vet all the time just to get heartworm medication. The process of delivery was quick and easy. My Malinois just got her heartworm test yesterday and it came back negative. Her fecal tests have been coming back negative too for parasites. My only complaint is I wish the chews were softer or more appealing to dogs. My girls will usually eat anything but spit these out. We mix it in different foods and they gobble it right down. We will continue to use this product for years to come. :)
This medicine is suppose to prevent hookworms. I put my dog on this medication March 31st, 2023 and gave her another chew 5/1/2023. My dog was diagnosed with hookworms 5/27/2023. My dog also does not like these chews. I must cut into pieces and feed with peanutbutter to get her to eat them.
I've been using this for years on all our dogs and the Battle Buddies foster dogs. Much better to give one chew that they like than to have to give two things and the liquid flea meds burned some of our dogs.
This was less expensive than getting it at the Vets and it came promptly. They got the prescription from the Vets office for this monthly flea medication
My dog was rescued and had every worm in the book when I got him. He had a really hard time getting rid of the tapeworms, and this was suggested by my vet. This chew gets gobbled up like a treat, and I like that it helps with routine deworming, in addition to the great prevention. My dog has had no side effects or issues with this medicine.
All was good for this big girl. So it looks like continuing monthly
Easy to get my product from my past place that I was getting it from which requires a doctors aprovel.
This medicine is great since it combines heart meds with flea and tick prevention.
These Sentinel Spectrum Chews are very easy to give and I like the peace of mind knowing our GSD princess Elsa is not going to get heartworm and such. Elsa has been on these from the start. Stickers come in the box to put on your calender so you get reminded when they are due. Elsa would not eat these little brown bricks, as they are hard not soft which is what we expected since the product is called a "chew". When we first tried she would show initial interest, then just spit them out. So we put them in a sealed, air squished out Ziploc bag (Ziploc bag = they stay put, no mess or bits flying) making them easy to crush with the butt end of a wooden rolling pin (any implement with a wider solid end, or a mortar and pestle would work too). Then, we mixed the crumbles with her food. Elsa has half a can of wet food mixed with her kibble (plus a 1/4 cup of water, she likes really wet food!), it is what she likes, which means the crushed pill is really hidden. If you only use kibble, the pill would still probably be sufficiently disguised, or you might consider getting a can of wet dog food, at least for the once a month dosing, to get ALL the med in the dog! I also like that we can safely give the frontline plus flea and tick shoulder spot drops in conjunction, without risking a problem, although we do tend to give two weeks apart, just because that is what we chose to do. Recommended.
Preventative treatment is a must here in Texas. The mosquitos carry heartworms. Without prevention, you pet will most likely get them. Heartworms kill if left untreated. So far I am happy with the Sentinel Spectrum chews. 4 of the 6 dogs will take them as a treat. The other 2 have to be tricked into taking them.
