I was supposed to take Reclast as per my endocrinologist but upon further research I learned once it is in your body and there is a negative reaction there is "no going back." This means you are stuck with this in your system. I have dercided to take Forteo because there isn't any chance of osteocronosis or breaking my femur! It has the least amount of side effects out of all the medicines I researched and it does not stay in your system for a long time.
