Tymlos is my choice. I could not tolerate the side effects of Forteo, which has to be injected at full dose from the get go. Tymlos is shelf stable, and it is possible to step up the dose slowly to get used to the medication more easily. I am up to 7 clicks and in the last 6 months my spinal bone density has improved greatly from osteoporosis to osteopenia levels. I highly recommend Tymlos. And if you are on medicare and have a limited income they will provide it free of charge.
