Tymlos is a great choice.
bone markers 1 before starting the medication for baseline
2 after two or three months
3 at sixteen month
You will probably always get a three month supply, because of shipping costs to the Speciality Pharmacy for your medication. I've gotten four months by talking to the pharmacy, but I'm on Forteo.
The endocrinologist I see orders bone markers baseline and then every three months. It can be easier on the physician if there is a standing order. I was slow to respond, so he added markers to the standing. Original Medicare covers them, but some insurance policies don't.
Baseline and at three month are worth the cost of finding out whether the medication is working. If your provider won't write for them or the insurance won't pay, the best price is at Jason Health.
One thing about both Tymlos and Forteo is that they almost always work. Some have reported here on Connect that they took these medications for two years without gain.
Some doctors remember from their training that bone markers aren't reliable. In the 1990's standardizaion, new reagents and the importance of an early morning fasting draw have changed that perspective.
I suspect your doctor is smart because he shares my order of medication Forteo or Tymlos and last and least Evenity. I think you are going to have good luck, lurawilson
