Regarding following Tymlos with Evenity, there may not be enough research to make doctors comfortable with that, but I think there is very little research altogether on these drugs.
I have taken Forteo, Tymlos, and now Evenity. I consider every one of them to be radical. Evenity only not that long ago had a black box warning. If someone had told me that I would be flinging myself out into this brave new world of medicine , I wouldn’t have believed them. The decision to take all these new age drugs was ten years in the making and involved a team of physicians who I knew and trusted. Their enthusiasm for the drugs is not based on years of study - it’s based on positive results so far.
I have been fortunate to not suffer any side effects. Of course, it’s possible to have side effects that are not obvious.
I read Dr Lana Simpson’s book years ago and consulted with her before I started the Forteo and the Tymlos. She is pretty even handed about the drugs. She’s all about lifestyle efforts to save bones, but has always said that she herself is open to taking the new drugs.
So, it seems that most of us do enter into this drug treatment regime after a lot of research and consultation.
