Our regular vet called back about an hour after the other vet called. She had come into the office on her day off just to check on Lucky's lab work and call me (how amazing is she? I don't even know a "people" doctor who would do that).
We talked for a long time about the Percorten and Pred. After reading his labs, she had actually called and talked to a specialist about them because they were so, well, normal that she was wondering if he could actually be Atypical, even though his labs at diagnosis showed Primary (if people want me to get even more long winded about the difference, I can :P). The specialist thinks that, because she had caught his Addison's so early that he still has a bit of decent adrenal function. But they still recommend injecting him every 4-5 weeks (about at the 30 day mark) rather than stretching it out more and more because the stress on his glands would eventually wipe out what function he has left and send him into a crisis. Clearly we don't want that. :P
So, instead we're going to work on gradually lowering his dose. He started at 1.6mL of Percorten for the first 2 injections, so we've lowered this dose to 1.5mL. We'll stay at that for a couple of months to see how he does and try another reduction. Eventually she's hoping to get him down to the lowest "recommended" amount which I think, looking at Novartis' website, would be around 1.2 mL. She's leery of pushing it further than that, though I do "know" a PWD who is on 1mL every 28 days and is stable (and he's a deal heavier than Lucky, too).
We also talked about lowering his pred. She said she wants to get his Percorten stable first and then we'll go about playing with his pred dosage. She said the earliest she'd want to consider that would be in a month. I'm ok with that. I just don't want to be staring December in the face (6 months from diagnosis) with him on such a high dose.
