I'm sorry to hear that your results weren't better. Most of the BMD gains from Tymlos occur in the first year of treatment.

While your BMD may not have changed much in the second year, remember that Tymlos was evaluated on the basis of preventing new fractures. The reduction in new vertebral fractures is where Tymlos really shines.

Here's a page showing Tymlos efficacy in terms of BMD and fracture reduction over the treatment period. Also note that the treatment period that was evaluated is 18 months while real-life treatment periods are 24 months.
