Hi, my husband has been type 2 diabetic for 12 years. He has been taking 4 metformin a day plus 40mg gliclazide for several years. He recently had his annual blood test and was told they were concerned about his liver function and to stop taking the metformin immediately and they would retest in 6 months. He checks his blood before driving and, not surprisingly, his counts are going up. We are a bit concerned that he was told to stop the metformin without being prescribed something else. Has anyone else had this?
