I started Forteo about 6 weeks ago & qualified for patient assistance thru Lilly Cares. I have had no particular side effects—Forteo was suggested to me about 17 yrs ago! I was 55 & neither of my female docs were aware of it. My last bone density was so poor that I decided to finally try Forteo. I took the biphosphonates from early 50s for about 10 yrs. I am very active but still bad bones! I hope you can make the best decision for you. Take care.
