Vet Review | Currently under 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. | In recent years, the company Bayer has developed a revolutionary flea/tick collar for both dogs and cats that is highly effective, especially in flea control, as well as providing moderately effective tick control. The most exciting aspect of this product is that it provides BOTH repelling and killing of fleas and ticks for up to 8 months!! While it is somewhat expensive, it is actually cheaper than purchasing 8 months of Revolution, Advantage or Frontline. In many areas of the country, this protection will last the entire flea and tick season, by just properly applying the collar. Another major advantage over collars developed in prior years (i.e. Preventic collar) is that Seresto is water resistant, and can be worn with confidence, even by dogs who frequently swim. The collar also has no odor, as well as a powdery, soft feel, in addition to leaving no greasy topical residue, like many of the other topical flea and tick products available. The collar is safe if chewed and/or even eaten by the pet, which was a problem with the old Amitraz based collars such as the Preventic collar. The Bayer company has also made it radioopaque, in case an overzealous pet did ingest the collar, so as to allow radiographic tracing and/or location should it possibly get caught up in the intestinal tract. The collar also has unique technology, in that the release of the active ingredients is triggered by friction of the movement of the pet's hair and body heat. The cat collar even has a break-away apparatus to allow for the pet to safely detach from the collar should it get caught on something outside. The reflectors on the dog product also allow the dog to be seen during the hours of darkness. While the collar is very safe for most pets, I have occasionally and rarely seen reactions in sensitive, geriatric or chronically ill pets. These typically involve transient itching, redness and hair loss at the site of adherence to the skin. While most of the time this will resolve on its own in a week or two, occasionally pets will develop enough irritation where the collar may need to be removed. The major rare systemic reactions seen in sensitive pets are mild lethargy and decrease in energy, but even more rare is the development of neurological symptoms, including weakness and/or seizures. I don't recommend that it be used in pets with a history of seizures and/or neurological sensitivity or reactions. While it is amazing for killing and repelling all stages of the flea life cycle quite quickly, it can sometimes take up to several days for the maximal effects to be seen with tick control and prevention. I, therefore, give this product an overall rating of a 4 out of 5, with an ease of compliance and efficacy of a 4.5 out of 5. |
