Husband was initially on 40mg pred for PMR/GCA and GP is monitoring the reduction (Rheumatologist died shortly after hospital IP assessment).
After a few weeks she advised 40->35->30 in 2 x 2wk stages - we phased over a slightly loger period.
Late September he saw GP and "blood markers were down considerably" (he didn't think of asking for the figures) and she advised 30->25->20->15 over 8wks. I persuaded him to request 2.5mg tabs to be added to his repeat prescription in order to be able to manage a 10% reduction stage.
He did so 'cos he thought that 8weeks was too speedy.
I put his tablets into one of those 7day comparment thingies to make life easier for him (he's not at all happy with medication).
The taper is nearer 5 months than 8 weeks and similar to one I've seen written out somewhere.
