@yogagirl57 they gave rats huge doses. Osteosarcoma has not been an issue with human use. The black box warning has been lifted for both Forteo and Tymlos. Forteo can now be used for more than two years. (Tymlos is similar but the manufacturer needs to do the same studies for longer term use ...)

@yogagirl57 My endocrinologist told me the same about Tymlos. I am a cancer survivor and. had radiation therapy so he said no Tymlos for me. He recommended Evenity and I'm going for my 12th and last injections of Evenity tomorrow. I've had no side effects with Evenity. I meet with my endocrinologist again at the end of November after a bone density scan. We will then talk about next step to hopefully "lock in" any bone density gains I have made on Evenity.
