My first osteoporosis medication was Fosamax. After 5 years or so I stopped also because I was to do some dental work and was concerned about the risk for jaw necrosis. My doctor put me on Evista (raloxifene) which I continued for many years, then switched to Prolia injections. The local place that did my recent bone density test suggested I consider switching to Fosamax. My Primary Care doctor advised me to see an Endocrinologist since he did not have the expertise for such a decision. As a person with cancer, always wondering about metastasis, I was very pleased to learn from Mayo Endocrinologist about "extra" benefit of Prolia.
