Hi and I can so relate to your doubts on the mentioned medicines, I have given up on taking any of them and least of all any
bisphosphonates the side effects are simply terrible specially
Boniva, there is a site about these meds and all the posters are those women who have taken them, you can look it up under "Boniva side effects" or http://www.askapatient.com/viewrating.asp?drug=21455&name=BONIVA, this is a forum where patients detail the side effects they had.
