ripley,
I wanted an anabolic because it builds bone, instead of preserving older bone. In building bone it remodels our bone according to our activities acually realigning the spicules for the best flexibility and resistence to fracture.

The bisphosphonates prevent remodeling, by accretion give you ischemic bone, weaker bone that is unable to repair itself, and blunt the effect of anabolics if taken first.

This left me with three choices: Forteo, Tymlos or Evenity.
Evenity begins as an anabolic then continues as a an antiresorptive. It is a newer drug with black box warnings about cardiac issues. It is a monoclonal antibody which blocks the sclerostin pathway. The effects of the the blockage of this pathway will be born by the bodies of souls brave enough to take those risks. I'll wait, realizing that the number one cause of death in the US is cardiac event.
Tymlos is a close choice and is thought to have slightly better bmd results. It can be given in adjustable doses. Our impeccable source of information and experience here is windyshores. (She invented the system of gradual dosing.) She'll be around any minute to tell you the other side of the story. I depend on her.
I chose Forteo over Tymlos because the prescribed dose is lower. Forteo 20mcg Tymlos 80mcg. And windyshores hadn't invented or hadn't revealed her clever method. And because Forteo has been around maybe 20 years longer with a great effectiveness record.
Some people have side effect with one , other or both Tymlos and Forteo. But the are eliminated from your system within 24 hours, so you aren't stuck with adverse effect the way you are with Reclast and Evenity.
The usual course with both drugs is two years.
Suggestions among the endocrinologist advising me are 1 year Forteo followed by Reclast, with resumption of Forteo 2 years Forteo followed by one year alendronate and resumption of Forteo. 2 years Forteo 1 year Reclast 2 years Forteo. No one advised Reclast first, Prolia ever or Evenity before real life trials.
Forteo lowers blood pressue in the first seconds after the injection. In some people it can cause headache or dizziness. I was careful in the beginning because my bp is already low. I took blood pressure measurement and sure enough my systolic dropped from 100 to 80, but I never felt it. No headache, no loss of balance. I've had no side effects, except my nails which I keep short are hard to clip.
