Go to www. Forteo.com, savings and services. Copay is either $0 or $4.

https://therxadvocates.com/ I think you pay a service charge of 70$ a month, then the Forteo is free. So it's actually 70$ a pen.
There is a new generic by Teva approved 11/23. I expect that there isn't much of a price break.
I sometimes travel for my pens because in most countries the cost is 100$ per pen.
