@tpinheiro29 Thank you so much for that information!!! I had not heard that before and specifically asked the endocrinologist about autoimmune implications. I complete teriparatide in April and am thinking to just go back on Raloxifene for maintenance. Seems the least side effects and worked for 10 years last time. I would be willing to do Forteo/teriparatide again if I need another booster down the road.
