Vet Review | Currently under review | I recently completed a small clinical trial using Flea 4X topical product for dogs in my veterinary clinic. And I must say that the initial reports on efficacy and safety has been excellent. With the main ingredient being the tried and tested fipronil, this product is very effective in controlling fleas, ticks, chewing lice and mosquitoes. It is also labelled to control mites that cause sarcoptic mange in dogs as well. This product is a wonderful generic alternative to the Frontline product that has been out for years. Clients have loved the economic savings of this product over similar topical flea and tick preventatives. It is manufactured exclusively in the United States, as well as having the trustworthy and reliable 1800petmeds label on the packaging. It is also water proof for those canine patients who spend a lot of time outside and/or swimming during the summer months. Clients are reporting back to me quick flea and tick killing that lasts up to several weeks in treated pets. I highly recommend this product to those canine guardians seeking out an effective and economic alternative to similar products on the market. | 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. |
