Did your doc or pharmacist tell you these meds caused your osteopororis? I find any mention of steroids, even 4mg for two days, causes some docs to tell me it is bad for bones. My rheumatologist denied this. I don't know either but I do know that the meds you mention are absorbed mainly locally. For me, age and cancer meds that eliminated estrogen were the culprits.

Osteoporosis meds can be very helpful and hoping you can stay on your COPD meds too.
