<<Disclaimer: Verify this information before applying it to your situation.>> My wife has both cd and Rheumatoid Arthritis. A bone scan indicated a need for calcium supplement. The Rheumatologist prescribed MIACALCIN, which is a supplement in the form of a nasal spray! Not inexpensive, but very effective. No need for the special care required after taking, and, according to him, having a much higher absorption rate than Fosamax. No problems caused with her CD Ask your physician Jerry Sprung
