My dog has recently been changed from Optimmune Eye Ointment to Tacrolimus 0.02% eye drops. I have been told that I have to buy it on script from a compounding pharmacy in NSW, when I live in Queensland. It will cost $88 plus postage for a 15ml bottle, which will only last approximately 1 month. Does anyone know if I can buy it cheaper? Or, if it is similar to the human compound of the same drug?
