I had excellent results w/Forteo in the spine and very good results w/Forteo in the hips. I forget my T-Scores now - but - in two years of use w/Forteo (2005 to 2007) I gained bone mass back to my 1996 DEXA T-score levels. The third year of Forteo my results were not as dramatic but STILL an improvement. AND whilst they recommend that you take calcium and vitamin D along w/the Forteo (as they do w/the bisphosphonates as well) I can not and DID NOT take ANY calcium supplement altho I did vitamin D.
Because I was NOT willing to even consider the oral bisphosphonates nor the hormone therapy such as Evista, etc. we did try the bisphosphonate infusions in order to reduce or eliminate the risk to the digestive tract. I was given pamidronate (Aredia) via 4 hr drip on two occasions. Both years I still had bone loss and NO IMPROVEMENT.
