Yes, of course. Gliptins and metformin are a popular combination, with a good track record. What I highlight in my article is the questionable off-label use of those medications. That is, (a) for purposes other than diabetes, and (b) by healthy people. That's a different scenario from yours. So, trust your doctor, and continue with your medication as prescribed. My articles are never meant as medical advice. I present the science perspective as it emerges from research.
