I started forteo a month ago after a spinal fracture. I am 76 and had been taking evista for several years. I was terrified of the forteo, but never want to experience another fracture. It has been surprisingly easy. I am very susceptible to side effects, but the most troubling effect has been fatigue. I now take the shot in the late afternoon so that I have more energy during the day for Pilates, swimming and weight training. I don’t like the daily injections, but that is overridden by the prospect of building stronger bones. Good luck to you.
