sharonkhale, the most common use of Forteo is two years followed by a year or two or Reclast. Options have expanded but standards haven't been reset and research isn't being done. I'm finishing a third consecutive year of Forteo. My doctor says I should stay on this medication until my lowest T score is a -1, No one has figured out how low long you need to be off Forteo for it to be effective. The effects seems to lose the advantage for the bones after 18 to 24 months. If your doctor and your insurance are flexible you could end up on Forteo long term or in any pattern. Most likely you'll be prescribed the standard 2 year Forteo 2 year Reclast.
It is good if you can follow bone markers to understand if and how well the drug is working.
