I have been taking some prescription medications that increase blood glucose levels. I was on prednisone for pneumonia and I covered that with extra insulin with little to no problems. I am now taking Lasix and my blood glucose is running about 40 points higher than normal all day long. My doctor says that I need to be on this drug but never mentioned that it would cause my blood glucose to climb. I found that out by the patient information given with the RX and on the web and then by my higher than normal readings. I really hate to keep taking more insulin, but I don't know what else to do. Any thoughts?
