Hi Anna:  Sorry but I have a couple other suggestions...  Try and print the Boniva (link) info that includes the "Important Safety Information (Injectable)" paragraph to make sure that the Dr is aware of this.  If you can't print this, can you take the package insert with you or have the Dr look it up in the PDR about the calcium issue?  Each of these sources all say the same thing about the calcium issue with regards to this med, and all other bisphosphonates.   If you aren't satisfied with his/her explanation, can you get a second opinion "just to be on the safe side" provided your calcium level *is* consistently below the normal range, on *your* labs test print out.   Good Luck again, and I hope you get a satisfactory answer to this and a resolution!!  If you need more help from any of us post back.   Best Wishes,   PF
