Comfortis For Dogs - Monthly Flea Control Pill

There have been a few oral flea control products that have come out in the past, however, the comfortis flea pill is the first one that kills adult fleas for an entire month. Program and Sentinel are also oral flea meds, however, they are designed to kill fleas in the larvae and pupae stages only - they do not kill adult fleas like Comfortis does. Comfortis flea is just the opposite, it kills fleas in the adult stages only and will not prevent the hatching and growth of larvae. Like Comfortis, Capstar is also a chewable, given by mouth flea killer that acts on fleas that are on the dog at the time the pill is given, however, it does not offer the month long residual effect that Comfortis does.

Comfortis is made by the pharmaceutical company Eli Lilly with Spinosad as the main ingredient. Spinosad works by circulating within the dog's bloodstream where it targets the biting flea's nervous system to cause paralysis and death, but, it is not supposed to have the same effect on the dog's nervous system as it does on the biting flea itself.

Potential Side Effects And Adverse Reactions From Comfortis

It is important to know that some dog's have had adverse reactions and/or side effects from Comfortis including but not limited to vomiting, decreased appetite, lethargy, hyperactivity and increased salivation. In June 2008, the FDA released a warning that some dogs have had adverse reactions when taking Comfortis and Ivermectin concurrently. Ivermectin is a common ingredient in heartworm prevention medication including Heartgard products. Always discuss the use of any new product, including non-prescription meds, with your veterinarian before buying and administering them to your pet. Be sure to include all other food, supplements, meds and products your dog is currently receiving. For our pets, we often wait up to six to twelve months before trying a new pet health product just in case any unexpected problems with the product come to light that weren't discovered in the preliminary trial stages.
