I am hypothyroid and my endocrinologist told me years ago that I would eventually get osteoporosis. I was diagnosed with osteopenia a few years ago and started the Reclast. It has helped a lot as I get a bone density scan every 2 years. I have had no side effects from the Reclast infusions. I have had 4 infusions. The nurse who did my infusion the other day informed me that I will not be a candidate for Reclast because of having 4 already. News to me. My doctor never told me this. But, I will see my doctor before my next infusion as well as having a bone scan before another infusion is scheduled. So, to answer your question,, another drug has not been scheduled yet. Hopefully, I will not need one. Please do not hesitate about getting Reclast. My endocrinologist is the best one in NYC (not bragging but he is the top expert) and he would not prescribe it if he did not think it would work. This year was the first time I had a side effect…a headache…that was it! I am your age as well. I blame every problem I have on my thyroid! Good luck and I hope I answered your question.
