cbartonsandiego, hi.
I haven't taken Evenity, but am taking Forteo and think that Forteo is a far better medication for osteoporosis.
Evenity does build bone faster and it is solid calcium heavy bone developed on the outside of existing bone.
Forteo works more slowly and in a different way. It removes older bone and replaces it with integrated canaliculated bone--less calcium dense with some flexibility resistant to fracture.
Both of the pth drugs Forteo and Tymlos increase chondrocytes which are help the joints but also form the structure for lost bone reconstruction in trabecular bone (spine and femur). This function is unavailable in the other osteoporosis medications.
Forteo has been around for 20+ years and more is known about the medication Evenity is newer so the advantages and disadvantages are not as well researched.
Another advantage of Forteo is that if you have undesired side effects, you can quit the medication because it leaves the system fairly rapidly, usually 4 up to 24 hours.
Side effects with Evenity can last the six months plus. Some people don't have side effects with Evenity.
While you are considering either medication give some thought about what you will take following the one year of Evenity or the two years of Forteo. You might consider 2 years of Forteo, followed by the usual 1 year of Evenity. Evenity is usually followed by Reclast or Prolia.
If you want to know every good thing about Forteo, I'm here to sing its praises.
Best wishes with your decision.
