There is a lot of negative reaction on the site, but I am 74 and had great gains from Evenity (ranging from 4.3 to 10,8 %) with a few side effects—some hives that I controlled with regular antihistamines and added dissolvable Zyrtec when they happened, and some inflammation in the rib and abdominal area. Both abated when the series of shots were finished. However the gains were worth it and I have now transitioned to Prolia for 1-2 years and then will do Reclast— both to preserve the gains. I have taken both before and tolerate them well. good luck to you.
