My 92 year old mother was given the shot Reclast and immediately experienced flu-like symptoms as well as stomach pain.  She suffered for a few weeks with major stomach pain.  Tests were performed and it was discovered that she has an ulcer, not bacterial based.  She has an extremely well balanced diet, and even exercises her mind and body.  No doubt in my mind that her ulcer was caused by Reclast.  I am appalled that her doctor administered a shot that lasts in the body for one year.  In discussion with the dr. he justified his procedure indicating that mom had osteoporosis.  However, there are other meds to be prescribed that are short term.
