I am relieved to see some positive comments about Reclast. I took Alendronate for 5 years with only minor issues the day of (which lasted literally a few seconds and was gone). I have been on a drug holiday for 1.5 years, during which my numbers have tanked. Forteo is out because I had a terrible reaction to it years ago. Prolia is out as well, as family members who took it reacted poorly. So the endocrinologist has recommended Reclast because I did well on the Alendronate. Reading some of the side effects experienced on any of the osteoporosis drugs is enough to send you to an asylum! Thank you to those who have shared a positive experience. I feel better about beginning Reclast after reading these posts.
