One more "side thought" to add to this discussion: There is no generic equivalent to brand name Tymlos, but there are now generic versions of Forteo on the market. So if you start on Tymlos, you don't run the risk of being switched to a generic by your insurance company. (This is important to some people and of no concern to others.)

I am 62, on commercial insurance, and I have a super niche financial reason for keeping track of this: In my state, if there is no generic equivalent for your medication, then any manufacturer's co-pay assistance coupon, e-voucher, etc., that you use MUST count towards your deductible and annual out of pocket maximum (even though it didn't come out of your pocket). In my (admittedly niche) case, this results in my out-of-pocket max being met by February and all of my covered appointments, procedures, and medications costing me $0 for the rest of the year.
