Comfortis question Does any one use comfortis for flea meds? I have been thinking about using this for Pistol and just wanted some feedback from any one here using it. You know pros, cons any problems. What about dosage do you give the whole pill? Pistol only weighs a little over five pounds. I would appreciate any input. |
I am going to watch this thread. I am curious about Comfortis too:) |
Make sure if you do switch to Comfortis that you do not use Heartguard for heartworm prevention. Heartguard is ivermectin and the two used together can cause a potentially dangerous interaction. COMFORTIS® and ivermectin interaction Safety Warning Notification |
My Westie takes Comfortis with no problems and . . no fleas! The big side effect is nausea and if the dog vomits within an hour of taking the pill, you must give them another dose. My breeder used it on her pet yorkies but my vet would not give it to Lucy because she has not reached 4 lbs. |
I use Comfortis on my miniature doxies. They do just fine with no sickness and eliminates all fleas. I have found nothing else that works. I give it to them and do not give anymore until I see fleas again, I don't want to put anymore drugs into their system than just have to. It usually takes 3 months before having to give another. I have used this since summer of 09. My yorkie is also to small to give this too. She gets revollution for heart worms and takes care of any fleas she may pick up. |
We don't use it, but there are some interesting reports coming out from people whose dogs have liver problems associated with it. It's such a new drug and I'd want to see way more about all of it and the potential problems before using it. :) |
Comfortis was tested for 90 days on dogs and the good news is, no one died. As long as the poor lab dogs don't die, then the product is considered safe to release on the market. Very sad. The studies done on rats (http://toxsci.oxford...t/full/67/1/144) over a longer period of time came up with very scary results (the doses they use in the rat studies are higher, but they do show the potential dangers of the chemical)... I currently use Frontline on Zoey with no problem or side effects that I know about or have noticed, but with all the sudden bad press and recent spikes in severe reactions from spot on treatments I'm planning on trying some natural remedies to see how they work out. I heard really good things about cedar oil and specifically about Dr. Ben's personal insect repellent cedar oil, which is fully diluted in a natural safe mineral solution. |

http://www.fda.gov/downloads/AnimalV.../ucm062334.pdf Medi-Vet Animal Health - Detail1 - 16576 - Comfortis (Spinosad) For Dogs, 5-10 lbs, 6 Pack, Pink - Flea, Tick and Mange (Mite) Control - Prescription Medications - Search By Brand - Medi-Vet Animal Health I agree with you, Crystal. It's just too new to know its long term safety. It was on the market for awhile before they realized that there was a potential dangerous reaction with ivermectin/Heartguard. |
The regular test went okay, but then the one where higher doses are given seemed to intefere with ALT results. It's hard b/c all drugs can affect the liver, but n ow that this is on the market, people are noticing that their dogs' livers aren't doing too well and the only change is this drug. I'd want to know how many pups this is happening to. They all have the potential for harm, but there are just some major concerns around this one. But then, I don't like Advantage Multi or Revolution either, so... |

I feel the same way about Advantage Multi and Revolution. I am very nervous about long term effects of the combination medications after what happened with Proheart. I feel much safer using something like Advantage or Frontline that has been on the market for years. Of course, the problem with that is that fleas are developing a resistance to the chemicals used in them with the constant exposure. |
I just Google "Comfortis liver." The reports are pretty subjective right now because we don't know if these dogs really had perfect livers before, etc. I'm just seeing a pattern that I don't like. :( |
I am so glad that I read this thread. I rescued a cute little Silkie/Yorkie Mix and her owner had been giving her Comfortis. So when it was time I bought it again and gave it to her and my puppy. I will happily go back to the topical for flea treatment unless someone has another suggestion. I will not give her the Comfortis again. I had been using Advantix K-9 before and I will go back to that. |

Are ticks a problem in your area or just fleas? If not, I'd stick to regular Advantage w/o permethrin. I have heard of too many toy breeds having trouble with it. Permethrin and Pyrethrin Toxicity in Dogs |
