I had a bone scan last week, and got the results today. My doctor told me my bones are brittle, and put the cause down to my use of prednisone. I have only used this drug once this year, and a couple of times last year. I didn't fully realise the effects this drug has the body. I have two alternatives: take a risedronate tablet once a week, or have an infusion, which lasts a year. I have chosen the later, and would urge anyone who has taken prednisone to get a check up. Better than falling over and breaking bones.
