Haven taken advice from this website I reduced the pred to 4.5 which involved two uncoated pills. Despite beefing up my breakfast my stomach was upset. Within a few hours I had nasty stuff coming back into my mouth, felt sick and lost my appetite. I couldn't sleep owing to a churning stomach which was slightly sore by the next morning. So I went straight back onto 5mg daily for a few days and used an antacid prescribed by my GP to settle my tum. I then went to plan B which was to alternate 5/5/3.5. This averaged out at the 4.5 which my GP advised and only involved one uncoated pill every three days. By eating masses of wholemeal bread each 1 mg morning(yoghourt was no good) I managed to cope although my tum was unhappy and my bowels on overtime. After 2 weeks I had had enough and reduced more quickly than advised to 5/5/2.5 which has put me back onto coated pred. Thank heavens my PMR is no worse although I believe that all of the stress caused has made me pick up a mild cold. I will stick with this regime for 4 weeks, have a blood test and then consult my GP.
I do so wish that coated 1Mg pred was available.
