@guinivere I have COPD also. I have taken Flovent (steroid) for year, and have also taken Advair. Both the meds you mentioned are combos of steroid and bronchodilator I believe (but check with a pharmacist or doc).

I don't personally believe these meds can cause osteoporosis. I think age and lack of estrogen does 🙂

I know that oral steroids like prednisone can cause osteoporosis but the meds you and I take don't have the same impact for the whole body and are more localized. Or so I have been told. The fact of the matter is, those meds are needed and without them you might have needed oral prednisone which would have been much worse for bones!
