Just want you to know that I also experience the same problem, in my opinion, with Lantos. I have had major diarrhea problems for over five years. we (including many Drs.) have used the process of elimination to determine if my meds were the problem.
Lantos is at the top of the list, of possible causes, or at least a catalyst to the problem. Tests on stool samples come back negative for any bacterias. I'm at wits end.
