@gracierose It's hard to balance the benefits vs risks. I think the big factors are your age, if you have generally good physical condition making you less likely to fall, and your DEXA score. I am 76 with a DEXA score of -4.1 in my spine, -2.7 in hips and in otherwise good health and fitness. My Dr recommended Fosamax but I refused because I have no fractures and don't believe the fracture benefits are that great. My Dr disagrees but respects my opinion.

With my reluctance to go on Fosamax, my Endo Dr said he would prescribe it at 1/2 the normal dose (35mg/week). He said that dose was still effective and would have less side effects than the normal 70mg/week dose. If you want to remain on Fosamax, you could ask your Dr about reducing the dosage to 35mg/week and see if your symptoms improve.
