Gliclazide is from the class sulphonylureas and does indeed stimulate the pancreas to produce more insulin. It is important to know how it works. It is complicated and if you are new to diabetes you might find this explanation a bit overwhelming. Food, usually carbohydrate increases glucose in the blood after eating it, and insulin is needed to move the glucose into cells where it is used for energy. A type 2 cannot produce enough insulin, or sufficient fast enough to facilitate cellular glucose absorption in most cases (or sometimes the insulin does not work properly). Glucose increases depend on the type and amount of food you eat and it would be useful to work out which foods send glucose soring (most peaks take half an hour after eating). Gliclazide helps bring the glucose down after a couple of hours. It's a balancing act. If you take gliclazide and don't eat, you are at risk of driving blood glucose down very low. Testing strips are essential otherwise you cannot know how high you glucose is going (allowing you to adjust your food) or if you glucose is going too low. You may notice you get "the shakes" when your glucose is low and it is inadvisable to drive. The DVLA therefore require diabetics on sulphonylureas to test before driving and then every two hours to make sure their glucose is above 4. Meter companies will often send you a free meter if you ask, but you need to negotiate with you doctor about getting test strips or cartridges on regular prescription. I did not find much problem after I explained why I needed to test. You have to remember many GPs do not really understand diabetes to any great depth (it's a complex disease) - at least they didn't when I first contracted it. Just one comment, did your doctor talk about metformin? Metformin works by helping the glucose into cells without stimulating the pancreas to produce more insulin and can work well in tandem with gliclazide. Metformin is the first medicine of choice according to NICE guidelines, but then there may be reasons it is not suitable for you. The problem with producing more insulin with gliclazide is that it may cause weight gain, which in turn is not helpful.
