Vet Review

I have started to use this product over the past several months and have mixed feelings about it. A big advantage is the ease of administering the beef and pork flavored tablet but it should be administered on full stomach. And while it avoids the oily liquid pesticides on the back that many clients don ' t like, if a pet is allergic to beef or pork this is a big disadvantage. The best thing about this product (which is similar to Capstar) is the quick kill of adult fleas working within 30 minutes and being almost 100 percent effective against fleas within 4 hours of giving it, and lasting for a month!!! (much longer than a Capstar pill.) A big problem is not only the expense but it also has no tick coverage. In my experience and opinion, I have also seen several dogs vomit when given this pill and it is really not supposed to be used in patients with seizure disorders, which is also a concern of mine in terms of safety. Along the same line, it is not supposed to be used in pregnant or nursing females, as from what I understand when the product was tested there were supposed loss of litter during pregnancy, poor weight gain of puppies and vomiting, the latter symptom which I have seen in clinical practice. In general I am always a little worried about products not approved for young puppies, as the puppies have to be at least 14 weeks of old, according to the label use of this product. It is not a cheap product, and for the above reasons I don't use it often even though it is tremendously effective against fleas. For the reasons stated above, I therefore give this product an overall rating of 2 with effectiveness (for fleas) of 4, the ease of use a 5, and the taste a 4. I still prefer Front line, Advantage and K9 Advantix despite the oily spot because of the increased coverage of parasites, and my concerns about safety

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.
