Those are the choices. I will be faced with that later this year. The doctor mentioned both, so I assume either one will work. I'm hesitant about Reclast since it's an infusion and there's no undoing it, but supposedly it works better. I'll think about it when the time comes!

I seem to recall a chart, and I'll look for it.

My thoughts are that following Tymlos or Forteo with Fosamax is preferrable over Reclast.

But first, if you take the Reclast injection, you don't have to worry about osteoporosis medication for a year or maybe two. The medication would maintain the density gains on Tymlos without much if any increase in density. And without gain in the structural integrity of the bone.
You probably know that the bisphosphonates prevent the normal acquisition of bone gained through remodeling. These antiresorptive medications work by preventing cells dedicated to removing fissured or weakened bone from reaching the bone. The add bone density by accumulating older bone.
If I ever have to stop taking Forteo, I'll take Risedronate because it is less effective and less enduring in the bone that Reclast or Fosamax.
Taking Tymlos or Forteo after any of the bisphosphonates blunts the effectiveness of those bone building drugs.
I haven't mentioned the risk of side effects which would be far milder than Fosamax, unless you are one of the many who don't suffer with these medication.
Bless your choice with wisdom and luck .
