Anybody here switched from Metformin alone to Jentadueto (linagliptin/Metformin combo drug)? I ask because of the cost differential and I can't find much info on benefits compared to one another. I see the EU is approving Jentadueto, but recommend usage when the max dosage of Metformin isn't tolerated or sufficient. I'm asking because I'm thinking of asking my doc about going to Metformin-only to save the $1000+ per year prescription cost.
