I also have an allergy to sulfa and I have osteoporosis in my spine. I have taken 2-months of Evenity shots already with no side effects.

Everyone is different- I tried Tymlos for 5 weeks and had headaches right afterwards as well as when I woke up and my heart rate went up to 90-100+ BPM while laying down after Tymlos. I am very happy with Evenity so far and hoping for some improvement.
