Let me add another non scary Reclast post. In December '23 I had a reclast infusion and because I had a friend in Ohio who had one the week before me, I was aware of the importance of being hydrated, taking 1000mg of acetemiocine and even a Claritin before hand. Neither my endocrinologist at the time or the infusion center mentioned this.
So well prepared I had the infusion, continued to drink water and and rest for the rest of the day. I experienced zero side effects. Then in December '24 I had another scan and saw great improvement in my spine; not so much at hip level. That said, the hospital where my previous 5 scans were taken, upgraded and the new system which included TBS might not be correlate well to the previous scans. Hope to have something to compare with at this year's scan.
