@prettyflower @gently -- Per "Great Bones" book (pp. 568-569), an anabolic, or bone-building, medication (i.e., Forteo, Tymlos, and Evenity) doesn't work as well when followed by an antiresorptive, or bone-remodeling, medication (e.g., Fosamax, Reclast). The antiresorptive medication blunts the body's bone-building response and reduces the amount of new bone laid down. I don't know if length of time between ending the antiresorptive drug and starting the anabolic drugs plays a role in effectiveness.
