I am having my first Reclast infusion tomorrow. I am grateful that I came upon this thread as there are more positive posts regarding the side effects. I suffered my second compression fracture a month ago. First one 7 years ago. Tried Fosomax but could not tolerate the esophageal discomfort. Sadly the use of supplements, diet, and exercise did not help me with my bone health and I havw had a steady decline of my DEXA scores. I have been so fearful of the drugs but have to do something. I'm 68 years young and otherwise healthy. Thanks for the tips on preparing with hydration, an antihistamine, and Tylenol. Had Inot read all your stories I would not have known.
