I reason that the big-step drops in dosage are being recommended so as to quickly determine the patient's actual dosage requirement after some initial heavy dosing to restore the patient's bloods/symptoms to more-normal values.
Especially as Fran mentioned, that we each have a different set of disease parameters, a determination needs to be made as to minimum tolerable dosage lest the patient perhaps be over-medicated on pred.
Doctors are obviously taught of the real dangers of higher dosage levels, and I suppose that they are counting on the patient to report back when the dosage suddenly isn't sufficient to control symptoms.
I have a very quick email communication directly to my pcp and rheumy, so in my case there wouldn't be any prolonged period of unnecessary suffering unless I didn't communicate my worsening condition. I actually tapered at 1mg/month until I was having serious discomforts and disabilities, but by that time I had been reading regularly on this specific forum so began adjusting my dosage taper when I was unable to sleep comfortably.
Different symptoms became critical at different times in my two+ years with pmr, and for each one I had to make small dosage adjustments, ultimately adjusting the "straight-line" taper schedule orered by my rheumy into a sort of "ski slope" curve that stretched way out from the 6mg/day level and onward. I am currently dancing between 1.5mg and 2mg/day as needed.
And fortunately my prescriptions have allotted me large bottles of medication, with the rheumy perhaps getting feedback as to my usage depending on how often I order another allowed refill from their pharmacy.
Allowing for the fact that I made my own adjustments to dosage, and so using far more pills than wuld have been indicated by the prescribed 15-month taper (from 15mg to zero), the original prescription lasted exactly 25 months before I had to come in for a second set of blood tests, and this was no accident. I believe that the amount of pills I used in two years was therefore a typical amount for an average pmr sufferer that my rheumy has had experience with of has read up on in the literature.
The bottle of (300) 1mg pills that I was subsequently prescribed just may get me to the finish line, zero mg, and that is my hope!
I do hope that the rest of you are being given ample supply levels for adjusting your dosage as needed.
