Hi Paul,I am 37 and also use Prandin. My endocrinologist Rx Prandin for me. I think alot of CF Dr's may not be thrilled about it, because any information written about CFRD states that injected insulin is ultimately the best, but Prandin seems to work for me for the time being. I have been advised that this won't always work and that insulin will be necessary at a later time, especially if I ever have a transplant. My endocrinoligist said he had one other CF patient using Prandin & it seemed to work for him, so that's why he decided to try it w/ me. It may be a case by case thing too. Where if you have high sugars, but are at a healthy weight, Prandin will do OK to just control sugars, whereas if you are underweight & can't gain weight & also run high sugars, then insulin would work best to offset the sugars you would need to eat to gain some weight. I happen to be at a good weight, but have the high sugars, so Prandin works well for me. One thing that I have found w/ Prandin is; about 2 1/2 hours after I've taken it & eaten, my sugars "bottom out" and I have to eat a snack before I get too low of sugars (shaky, disoriented, sweaty, etc). One good thing is to take it 15 minutes or so before I eat, then I don't "bottom out" as badly. I hope all of this makes sense to you <img src="i/expressions/face-icon-small-confused.gif" border="0">
