First, I would like to thank Justin for telling me about this group. Hi Suze317, With the guidance of my new primary care doctor, I chose Tymlos. It is less expensive and, as you know, there is the convenience of not refrigerating the drug. Although Forteo has been around longer, it was explained to me by the Wake Forest Baptist Fracture Division, that the chemical makeup of both drugs is quite similar. Also, Forteo is a 24 mo. drug vs. 18 mo. on Tymlos. Unfortunately, both drugs are toxic! However, both my primary doctor and Wake said one fall and I won't recover. They believe I don't have a choice. My chiropractor preferred I take bone supplements, magnetic treatment and bi-monthly iv drips. The latter was not covered by insurance. While a much healthier alternative, sadly, our government doesn't believe in covering anything that is not traditional meds. I hope this info helps!
