I have been getting very painful reaction from my prednisone. I am looking for the coated tablets and they do not sell them in the US or Canada. Does anyone know how I can obtain the coated tablets. I am still on 20 mg and will be taking this medicine for at least another 2 years for GCA and perhaps longer. I do take a PPI and a meal prior to taking the pred. Can't do too much more than that to coat my stomach. Thank you.
