I took teriparatide the generic of Forteo for 14 days. I felt fine until day 11 when I became so dizzy I had to sit in a chair for 3 hours before I could walk without fainting. Also I was sweaty, low blood pressure and the room was just spinning. On day 14 I had a more severe episode and my vision grayed out and I was almost in a complete faint. Fortunately I was at home for both episodes and did not faint or fall. I did faint and fell on cement before I started teriparatide and broke my shoulder and arm. My DEXA scan is normal and yet my endocrinologist insists I take a bone med. I think anyone’s bone could have broken falling on cement as I did even without osteoporosis. She is the only doctor I have who thinks I have even osteopenia. I take calcium and eat a calcium rich diet. I am going to change endo doctors because she is pushing too hard.
