I like your comment of risk/benefit. It's kinda how you weigh the benefits and risk.
There is the benefit of avoiding medications and possible side effects vs the benefit of avoiding fractures. I decided on Evenity and can't wait for my DexaScan in a few months.

For me, the possible side effects of the medication were certainly less severe than the benefit of avoiding another hospital stay with the possibility of another fracture.

Actually, my bone doctor pointed out that osteoporosis can be FATAL, and in my case it was a real possibility in the next few years. He felt Evenity was the fastest acting and therefore best choice for me.

For example, I often hike with my dog where there is little/no cell phone service. I leaned over to pet my dog and my femur broke into at least 5 pieces. Fortunately, my phone was in my pocket and still working and I had a cell phone signal. If not, I could have been there for hours.

As it was, I was taken to the hospital where I stayed in skilled nursing for a month. Those nurses and therapists were bossy as heck .... but the statistics show that lots of people with hip/femur fragility fractures die within the first year. (Look it up ... you don't want to be there.)
10 months later I was in the bathroom putting on deodorant when I coughed. I heard a pop from the fractured vertebra and fell .... fortunately, I did NOT hit my head on the porcelain tub or toilet. Once again I was lucky. I know someone who did die from falling in a tub.

We all have to weigh the risk vs benefits based on the information at hand.

PS .. I do have a family history of osteoporosis so had exercised, walked, weight lifted, taken calcium supplements and Vit D and HRT. That background also factored into my decision.

If Evenity doesn't work, I am going to be seriously depressed.

May I ask what medication you are taking after completing Evenity?
Thanks : )
