Vet Review

This topical product that has been around for years is really a potluck type product in my opinion and experience. Many of my clients, who could not afford the other commonly veterinary recommended topical flea/tick pesticides, have found this product a quite helpful much more economic and effective product than the more expensive competitors. . However I have had equal number of clients, who have used this product, been quite disappointed with the results, and their infestations seemed to have gotten worse after starting with this product. I personally don't recommend this product,for my biggest concern that overrides any economic savings that clients have, are the sometimes serious side effects I have seen with certain sensitive pets in my practice and experience. This has ranged from local irritation and greasiness in the coat, to an almost burn like eruption at place of application, to more serious systemic effects like excess drooling, ear itching/irritation and in rare cases neurological side effects including suspected seizures shortly after application. Although these side effects are not common, I feel their severity over rides my ability to recommend this product, I would stick with the more widely veterinary recommended products like Frontline, Advantage or Advantix. I therefore give this product an overall rating of a 2. Its efficacy is a 2 and its ease of use is a 4.

Parastar Plus combines the proven performing main ingredient of fipronil with cyphenothrin, which allows for more rapid killing and treatment of fleas, ticks, certain mites, and lice. This combination allows for this topically applied product to begin killing within an hour. In my experience, most of my clients have reported higher efficacy and better satisfaction for tick control over fleas. It seems to be easier to dispense out of the applicator over competitor products, and especially with lighter colored dogs the product does not seem to stain. However on occasion, I have seen a sensitive darker coated dog have some mild bleaching at the site of application. With some longer haired dogs, I have seen it leave an occasional slightly sticky spot at the site of application as well. Like many of the competitor products, it is touted as waterproof, however, I try and recommend that clients do not bathe dogs for 2 or 3 days before or after application, as some feel that this may affect the efficacy of the product. In my experience, I have found that this product is better at preventing problems rather than controlling already heavy flea infestations, in which case I usually will go to one of the newer oral tablets for flea/tick control that usually kill rapidly within 30 minutes. Another limitation of the product is that you can't use Parastar Plus on less than 4-pound dogs, which is an added benefit of topical prescription products like Revolution. As with any product of this type, occasional itchiness, and/or irritation/agitation from applying the product may be seen, but I find this side effect less common than with competitor products. It is also important for clients to understand that it is critical, especially with heavy flea infestations, to also focus on treating the environment as well. Overall this product has performed better for tick control and prevention than for fleas. I give it an overall rating of a 3, with an ease-of-application rating of 4.5 out of 5.

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.
