I took Alendronic Acid (along with calcium/vit D) with no side effects for six years after a wrist fracture and being diagnosed with osteoporosis. I had a second bone density scan that indicated the bone density had improved and the diagnosis is now osteopenia. I had a chat with my doctor and we agreed that I stop the AA for two years (continuing with calcium/vit D) and then have another bone density scan. I hope, with lots of walking/Pilates, and a generally good diet, my bones won't lose density but will need to deal with it if they do. I belong to the National Osteoporosis Society and it's useful for keeping up to date with the latest research.
Anya - as the calcium is so chalky, I've always had this (irrational?) fear that my insides could be furring up like a kettle. My doctor just laughed when I mentioned this. Should those of us taking large doses of calcium (even with D too) have a blood test every once in awhile to check our arteries aren't calcifying?
