I started forteo a month ago after experiencing a spinal fracture at T8. I had been taking evista and holding steady, but after this episode my endocrinologist suggested a different approach. I had been reluctant to use injections because I’m very susceptible to side effects. So far forteo has been a good solution. Worst side effect has been fatigue so I now take the shot at the end of the day. Good luck to you. These decisions are difficult.
