My 20 yo Arab was recently diagnosed with the early stages of Cushing's. His ACTH, when tested at the beginning of July, was 38. Thankfully, he is not IR. I'm going to start giving him CTB and .5 mg of prascend at the direction of my vet. My question is, is it still possible to buy pergolide and if so, where can I order it (with my vet's prescription)? She only sells Prascend which I understand is far more expensive. Thank you in advance.
