Vet Review | This product is a wonderful economic alternative for clients who have used the Frontline product. It contains the same exact main ingredient as Frontline, Fipronil, which has been probably the number one used flea and tick preventative ingredient by veterinarians over decades now. Not only does it kill fleas and many species of ticks that carry Lyme and other diseases, but also can help in controlling scabies mange mites, as well, in those cases. It certainly is a much cheaper alternative to Frontline or Advantage products. Some excellent advantages include it being waterproof, as well as being safe to use in pets as young as 8 weeks of age. There may be a rare skin irritation side effect at the site of application, but other reactions are even more rare. I have occasionally seen digestive upset with this product. I would also not use it in dogs with a history of chronic seizure disorders. Because of its long-term reliability and safety, I give this product an overall rating of a 4.5, with an ease of application of 4.5. | Because of the difficulty for some clients in getting their cats to take pills, the development of this flavorable suspension to mix easily with their wet food has made compliance and efficacy of flea control a lot easier. Getting felines to take medication can always be a challenge. When not accepted in food, many clients have found mixing in various tuna or clam juices, oil, broth, gravy or sardines another way of administering this and other medications. As mentioned in my product review on program tablets, this product works best when given with meals for maximal absorption as well as before fleas are firmly established on the pet and in the home. It works by preventing development of flea eggs and larvae by in essence sterilizing the adult fleas who happen to bite the animal. The product does not kill existing adult fleas and must be combined with other products like Capstar or topical Advantage or Frontline in pets with active flea populations. I find it works best as a preventative before flea season. Many clients will chose to use this and other flea products year round due to the warming of the climate and the unpredictability of the flea season. I give this product an overall rating of a 4 with an ease of use and taste a 5 and efficacy a 4. | Sentinel is a wonderful combination of the heartworm prevention pill interceptor and the flea control product program both in this one pill. Many clients enjoy the convenience of having such broad acting internal and external parasites in one pill, without having to worry about giving two separate medicines. Lufenuron, which is the main flea control ingredient, stops the flea life cycle in its track at the egg and larval stage, thus being like a birth control pill for fleas who get on our pets. Given that the main problem of fleas is how rapidly they reproduce, this pill literally stops escalating growth of flea populations, before they can become established in our homes, where most of the flea life cycle occurs. The main disadvantage to this product is that it does not kill or repel adult fleas, so in situations with already established heavy infestations, it is best combined with a great topical product like advantage or front line or with the oral adulticide flea pill Capstar for maximal effect. The only other rare disadvantage I see is the slight increase in reactions when two products are combined into one like this, but fortunately this is not common in clinical practice. With milbemycin for prevention of heartworms and controlling and treating most common intestinal worms, I overall highly recommend this versatile product. |
