I was on Evenity for one year. I tolerated it very well - no issues whatsoever. DEXA and TBS showed good gains. My journey with osteoporosis meds is on this site under "Prescribed Tymlos after Evenity."
I was in the same boat - after finishing Tymlos I needed a new doctor and felt anxious about the timeline. Then I dialed back on the anxiety because I absolutely know that stress is terrible for my health and I don't want it in my life. I found a doctor who agreed to meet with me on a video conference the next day even though the usual wait for an appointment was 8 months. So I got lucky. Very lucky. I finished Tymlos 3/15/25 and my Reclast infusion was 5/12/25. My doctor put me on a drug holiday because I had been experiencing extreme fatigue and joint pain, and she thought it might be from the Tymlos and wanted my system to calm down. She was right as the fatigue and joint pain were gone in a month and haven't returned.
You're absolutely right that you can't foretell how you'll react to any drug. You've obviously educated yourself thoroughly. I will say that when I relaxed about the whole thing, I found it easier to tune into my intuition about what I should do. What I see from what you've mentioned is that your cardiac condition is stable and you seem to be more concerned about your autoimmune disorder.
Do let us know how you get on and what you discover.
Best wishes to you moving forward.
