I need an advice. I was on Evenity for a few months but had a very bad allergic reaction. My back hurting more than before, hives, headaches, etc. I found a new doctor who prescribed Tymlos and told me to start right away. ( I have very severe osteoporosis case) . It has been just 3 weeks since my last Evenity shot and pharmacist told me to wait and let Evenity to wear out at least 2 weeks .Not sure who is right in this case. Anyone have any thoughts?
