I am reading "What Your Doctor May Not Tell You About Ostyeoporosis" by Felicia Cosman, M.D., which was recommended by someone on this board. In the book she makes a very good point about the fact that once you stop taking Forteo, you need to start taking Fosomax or some other bone building drug or you will lose the bone mass you have gained from the Forteo. Many of those who have posted threads here say they cannot tolerate Fosomax or Actonel. I am doing all of this research before agreeing to start Forteo, as prescribed by my doctor. However, what happens if after taking the Forteo for 1-2 years, and spending the small fortune that this drug costs, and hoping against hope to not develop bone cancer, you find that you cannot tolerate the Fosomax, etc. Seems like, at that point, you would just start losing the mass you have gained. I just had the DEXA scan two weeks ago and have not previously taken any osteoporosis meds. I am thinking that it might be wise to try the drugs usually prescribed for less severe cases than mine first to be certain that I can take them forever after the Forteo. Of course, two years down the road they may have better solutions. I am going to doctor next week for the 24 hour urine and parathroid tests before making any decisions. Just thought some of you might have some input here. Thanks
