Hello there. Welcome to the joinery of no sure answers as everyone is a bit different. I have no experience with Tymlos and was not offered that as an option. I wonder if that is more popular in the States? I am in Canada. My T-score was -3.5 and I had experienced 13 consecutive compression fractures in my spine when I went on Forteo. It literally saved my life. That was 8 years ago and I have not fractured since. Now I am need of another booster and had hoped to start Evenity, but still waiting for approval. I have researched and heard very good things about it on this site about Evenity. For some reason, Forteo was approved, and even though I already did the 24 months of it before, I have agreed to 6 months while I await approval for the Evenity. This time I went with generic brand of Forteo and find no difference to when I was on brand name. In fact, perhaps less initial side effect of mild headache and upset stomach. Forteo provided a travel case with refreezable ice pack to pick up from pharmacy for travel. Generic brand did not, but pharmacy just gives you a freezer pouch to get you home with. Hope that helps. : ). I am now 66 yrs old and very active with 6 grandchildren!
