I have been on pred almost continuously for about 18 months - only coming off of it for a few weeks at a time. I know it is advised to take calcium supplements to prevent osteoporosis and was prescribed calcium D3 forte months ago. However, I am prone to kidney stones (calcium) so have never taken them in case it causes more stones - couldn't cope with renal colic and a dodgy chest! I drink lots of milk and eat yoghurts and cheese - is this enough for me to not take the supplements? Is anybody on anything different that I could suggest to asthma nurse?
