Not for me. Never had any side effects.

I had bad muscle pain in my back plus headaches and diarrhea. They started a couple days after the first pill and intensified. I only took 2 pills and that was it. I'm going to see a different doctor at the Cleveland Clinic. I also had back pain with Evenity and stopped after 11 injections. I'd love to go back on Forteo. I took it for 8 months without any side effects but my alkaline phosphatase became elevated so I was taken off of it. I did some research and I guess that can happen but my doctor said no. We'll see what this new doctor says.

No muscle pain, but after 9 months I developed severe acid reflux and had to stop. Otherwise no other side effects.
