Metformin vs. Metformin XR

Hi All!

Looking to see if anyone has had any experience with the effectiveness of Metformin versus Metformin Extended Release.  I am a T1 with a great deal of insulin resistance so I take this med along with insulin from my OmniPod Pump.  Over the past year, I have taken both the regular Metformin and the Extended Release versions and seem to be having much less luck with the Extended Release keeping my BG numbers down.  I am going to be in touch with my Endo to look into changing back to the regular version.  Any thoughts or experiences that you could share would be greatly appreciated!



Hello I am also a t1 with insulin resistance. I have taken both metformin and er, I myself had lots of stomach problems with the regular metformin. I prefer the er. I am not on the pump though. I use novalog and lantus to control my t1. The combination works well for me but I am considering using the pump.

i also have insulin resistance and polycystic ovary syndrome and type 1 diabetes so metformin is a God-send!

ps....I prefer the regular metformin to the ER kind. i have no problems with it especially with using multiple daily insulin injections
