Forteo - Is anyone having bad side effects like immune system problems and nushea?General feeling g?

I don't know what you wanted to say regarding a general feeling of being??? With no personal experience with Forteo, only long experience with thyroid hormones and autoimmune disorders, I can tell you what side effects have been reported pertaining to your question. Nausea is a common side effect of Forteo and transient hypoparathyroidism is the only autoimmune-like side effect I can see. For a longer list of possible side effects you can go to this link:

Note particularly the common ones as these are the most likely ones you may have a couple of. This information doesn't replace the counsel of your Dr. or a pharmacist. I hope you are feeling better by now.
