I am a 56 year old African American woman who has been taking steroids for several years due to a chronic disease in my lungs called sarcoidosis.  This condition involves a myriad of symptoms including joint and muscle pain, shortness of breath, fatigue, and migraines. My health condition was compounded with other chronic diseases i.e. fibromyalgia, thyroid, acid reflux intermittently, steroid inducing high eye pressure, and chronic cystitis.  Moveover, I am also chemical sensitive in that the usual dosages of medications are cut in half to manage my conditions.  My recent dexa scan revealed that my osteopenia has worsened since the last annual exam due primarily to steroids.  Currently my BMD measures at Femur Neck 0.776 g/cm(sq) with a T-score of -1.9 and the L1 region of my spine with a T-score of -1.3.  Because of my chemical sensitivity and chronic conditions, I have been taking "mild" dosages (<15mg) of different steroids.  I am now taking only 5mg of prednisone, but it may decrease or increase depending on God's healing power.  I have read Fosamax may cause gastro problems, but one study reported it showed better results than Actonel.  Although, another study showed Actonel works faster.  With my daily regimen of other medications (Levoyl, Prosed, Triam HCTZ, Travatan Z), 1200mg of Calcium with Vitamin D, Multivitamin, 500mg Vitamin C) as well as with my aforementioned chronic illnesses, is Actonel or Fosamax a better match for me and are there adverse reactions in either with my existing medications?  Your insight and medical advice are greatly appreciated.
