<<Disclaimer: Verify this information before applying it to your situation.>> I was diagnosed with it in June 1997. At that time my rheumatologist gave me a choice of Fosomax or Miacalcin (nasal spray). He suggested the Miacalcin since it has few side affects. I have been on it since and it is wonderful - no pills to take - also easy to take when you travel. And the good news is that I had another bone density test in June 1998 and my osteoporosis had improved. I have friends on Fosomax who have had gastro problems from taking it and there are a lot of other side affects.
