I have had osteoporosis since 2020. I also have COPD, which developed as a post-COVID condition. It was diagnosed in May 2022. I took Forteo & then generic teriparatide (daily injections) for a total of 4 years, prescribed by my endocrinologist. That resulted in significant improvement in my bone density. In May 2024, I got an IV infusion of Reclast. A year later My bone density had improved again, going into the range of osteopenia, so my doctor ordered a second infusion for 2025, which I received in July. I have never noticed any side effects from reclast.
