I'm on Forteo as a short term measure because I already did the full 24 months in 2016 with good results. I'm suppose to be on Evenity, but waiting for approval from my insurance. Now I'm debating to just take my chances and stay on Forteo as hearing so many concerns now on the Evenity. It is such an unknown journey. My T score is -3.5 so had to be addressed. I guess if you have a bad reaction to Evenity, you can look at Forteo as an option? I scared too, but try to remember there are so many others taking Evenity with no side effects and good results. Best of luck to you : )
