Hi again standingfirm,
In answer to your question ~ yes, typically a patient starts on a high dose of ATD (whichever one they choose) and as the levels drop, adjustments are made until they arrive at one (usually fairly low) dose that successfully maintains normal levels for the patient. That doesn’t mean you may not need further adjustments, since the antibodies can flare up or calm down randomly, but the usual progression is from a high dose to a relatively low dose.
I’m so glad we can help. I remember how it felt to crave simple, good information when I was newly diagnosed, and how good it felt to find this board ~ it’s a true blessing, and I’m also blessed just to be a part of it.
