Hi-My grandson has been on steroids (Pulmison 20 mg, the 10 days on & 10 days off regime) for about the last two years. I'm a little concerned as his bone density scan has now revealed "severe osteoporosis" and we've stopped his steroids. He was on a chewable Calcium & Vit A supplement which obviously was not adequate.His Orthopaedic Paediatrician has now prescribed med's specifically for the osteoporosis and recommended that we phone his Neuro Paed. and advise him about the effect that the steroids have had & to ask how do we continue with his steroid treatment/dosage! Also, how often should our boys be going for bone density scans if they're on Steroids? Does the "Osteo medication" only halt any further detoriation, or is the damage reverseable? Please, if anyone has had a similar experience or any advice to offer??
