I have recently stopped taking Gliclazide as guided by my GP. The result has been extremely high blood sugar readings, mornings tend to be 13 and during the day are 17 - 19. I'm Type II, I am taking Metformin morning and night, Simvistatin at night and my current insulin is Levemir 25 units at night, since stopping Gliclazide it has increased from 15. I am in contact with my GP and at the moment I just seem to be increasing my insulin and this is having no affect whatsoever. I have an annual review with the specialist nurse at the doctors surgery on Thursday and no doubt the doctor will be called into the review as well. Has anyone else experienced this? What was the course of action? Back to Gliclazide or change of insulin?
