i can only tell you from my experience with prolia i had 1 shot last november and a severe reaction i was given a prednison pack and that did help but as it wore off the side effects came back in early december i suffered my first compresion fracture. by the time it was diagnosed it was pretty much healed so i did not opt for surgery. may of this yr the 6 monhs for the prolia shot was up and some of the side effects were better but i was now taking 10 mgs of the prednisone and methotrexate for ra that had developed. i am 80 myrs old and no one in my family had ra no symptoms or pain before prolia shot. i asked my dr if the prolia shot could have caused the ra and he said possibly we will never know but i know i was fine until the shot. in august this yr i had another compression fracture due to stopping prolia now my dr want me to go on evenity i think not. these drugs are powerful and if you have a reaction the side effects can last for months and in some cases years. i will have ra now forever and will need medication for that. if i could go back i would never have taken that shot it is pure poison. the drs know very little about it bit yet they give it freely. i have done alot of research about it and have heard worse stories than mine and you must be very careful with your teeth and any dental work because it can effect your jaw. i still feel i have effects from the shot but now with the ra it is attributed to that who knows. right now i am doing nothing because i really do not know what to take because if you have adverse effects that medication needs to leave your body before you can try another. just a vicous cycle of pain and uncertainty. i never knew anything about prolia and i do wish someone had warned me so that i could make a decision about it. i have heard from people who took it and it was fine but heard from more who were not. i hope this helps with your decision good luck
