In case you're not ready for a 40 minute presentation, the key takeaways are this (summary slide of the presentation):

Choose Prolia if:
Your T-Score is -2.5 or lower and you can’t get Evenity, Tymlos or Forteo.
Your T-Score is between -2.5 and -2.0 and you can’t get above -2.0 using Fosamax, Reclast or HRT

Keep taking Prolia until:
If taking Prolia less than 3 years, take until T-Scores reach -1.5
If taking Prolia 3 years or more, take until T-Scores reach -1.0

To transition off Prolia:
Start Fosamax or Reclast right after Prolia treatment (exactly 6 months after last injection)
Monitor your serum CTX level for possible dosing / redosing with Reclast
