Pros: Easy to use, effective in killing parasites (AND MY CAT)
Cons: Lethal side effects,
My 5.7 lb, 4 month old kitten was prescribed Revolution (blue tube) for presumed ear mites...
He had been fighting a URI since we adopted him from a shelter- at the time he was given Revolution he was on his 4th antibiotic (Azithromycin) and had been on it for 1 week. So I would argue my vet broke the BOLD statement in the package insert "DO NOT GIVE TO SICK CATS." My vet also administered 3 vaccines.
The day after Revolution was given, my husband and I were not longer being bitten at night by bugs.
My kitten was progressively lethargic and eventually stopped eating all together. We force fed him for days. My vet refused to believe it was Revolution, so I got a second opinion.
He accumulated fluid in his abdomen. Thousands of dollars in vet bills, we've determined he has severe liver damage and hepatic encephalopathy. The fluid was due to the fact that his liver had stopped producing albumin. He has been hospitalized for 4 nights, and we likely will stop treatment tomorrow and euthanize him.
There is no doubt my vet made errors in his administration of this product, and we *will* be taking legal action in this case.
However, please be wary and extremely vigiliant if you choose this medicine for your pets. By definition, my cat was indeed sick, and should not have been given the medicine, but if having a URI is enough to make this drug lethal, should it really be on the market?
Pfizer has already agreed to pay for a post-mortem on my kitten if he doesn't make it... I think that shows their both their interest and lack of knowledge of what this drug is capable of.
