Side effects:
For four months, I have been on Tymlos. Early on I experienced rapid heart rate for 2-3 days. A couple times it happened when starting a new pen.
Why Tymlos:
I have had osteopenia 7-8 years pretty much stable. I had taken Fosamax during that period. I am 77 with a family (mother and aunt) history of fractures and hunchback (in the 80s). My endocrinologist wanted me to start with Tymlos and if that doesn't suit me then switch to other meds. The reason being Tymlos after bone meds like Forteo, Prolia, etc. is not as effective but reverse gives better results.
