Vet Review | 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. | 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. | For my clients who prefer an effective non-pesticide manner of preventing and controlling fleas on their dogs and cats, program offers a wonderful alternative. When this product first came out, I used to educate my clients on the fact that it was in essence a birth control pill for fleas. The main ingredient lufeneron is an insect growth regulator that does not kill adult fleas, but sterilizes adult fleas and prevents them from laying eggs that develop into larvae and future adults. Each adult flea can lay up to 2000 eggs in its life. It is because of this effect on flea development which makes program such a wonderful preventative. For existing flea infestations, I don't find this product works as well unless it is combined with oral Capstar, which kills adult fleas on cats and/or topical products like Frontline or Advantage. I have found this product both very safe and effective with only rare side effects seen i.e rare digestive upset. It is best given with a meal for maximal absorption which is hard on some kitty owners My overall rating of this product is a 4 with ease of use a 4, taste a 4 and efficacy a 5, in particular for preventing flea infestations before they become established. |
