Which answers what I thought was your question. Then even though it isn't the answer you asked for, I sent it.
Personally, I think Forteo is the better medication. Unreasonably. Except it is more biologic, though there isn't any comfort in what it is extracted from. It is (said to be) more effective in the spine. Spinal fractures are my greatest fear. I'd prefer a hip fracture over a spinal fracture.
But I wasn't trying to say that. I was trying to be neutral.
Tymlos works better in the hips. It is less likely to cause hypercalcemia because of the more transient elevation of calcium. I've read that it is a little less likely to cause nausea and/or dizziness. I do like the downside of refrigeration with Forteo, since that is why it doesn't need phenol as a preservative. I'm happy that Forteo is 20mcg and not 80mcg. Even though (and even since) absorption makes it 28,8 for Tymlos and 19mcg for Forteo.
You really do have to question everything I say. I really am a one trick pony.
