Is it safe for a type 2 diabrtic that takes metformin 500mg, lisprinol10 mg,60 mg of cymbalta (duloxetine) to take dexstrim max ?

Probably ok: Current formulation of Dexatrim max contains caffeine, cocoa, green tea, plus several minerals/vitamins. It's probably ok, but may raise BP in people who are sensitive to caffeine. You should definitely show it to your doc before you try it, and if you try it, monitor BP. Weight control is so important for diabetics, and SO hard! Don't give up, and do whatever exercise you can.
