Trouble took it for years, but was taken off it when the osteosarcoma was diagnosed. The info sheet in the box indicates it is contraindicated for dogs with history of tumors. I called Novartis and asked about it and they will not speak to pet owners, only veterinarians.
The Pros - no more breakouts. Trouble continued to have mild episodes of itching and licking, but nothing as severe as when she wasn't taking it.
The Cons - the cost. The price has come down, but the dosage is based on weight. If you are giving 100 mg or more it is quite expensive, something a lot of folks wouldn't or couldn't do long term.
There are things you need to understand about the drug if you want to use it. It depresses the immune system, if you have a dog who is subject to illness, I wouldn't risk it. You cannot give live vaccines if the dog takes this drug. I had to remind the vet on the first round of vaccines after Trouble started taking the drug.
Bob was reading their website this morning prior to me posting, and it seems they have changed some of the original information. He could not find the specific contraindication for tumors, and it now recommends treatment for several months which can be repeated again if necessary. At the time we were using it there was not a limit, it was recommended as an ongoing treatment. For me that raises a red flag.
