I consulted four surgeons before having back surgery, and the one thing on which they all agreed was that I should get Evenity shots prior to having surgery. I did this for 6 months at which point I felt that I could no longer tolerate the side effects of this drug. The most benefit from Evenity occurs in the first six months, and both my surgeon and the provider treating my osteoporosis agreed that 6 months would be sufficient. It has now been 7 months since my back surgery, and I seem to be doing just fine. Many people seem to have no problem having Evenity shots for 12 months, but others (me included) are not so fortunate. If you can manage the side effects for another three months, that would be good, but if not, discuss this situation with your doctors and see if 9 months would be sufficient. If it is necessary to see more than 2 doctors, do it. In my case, I developed hypertension from this drug and even ended up in the ER at one point with a hypertensive crisis. As much as I would have liked to continue the full 12 month course of treatment with Evenity, it was not worth having a stroke. My blood pressure started to return to the normal range shortly after getting off the drug.
