I was on Glic for over 3 years, and was successfully controlling my bgl, with an HbA1c of 42 last year. Then last month I had a blue light visit to A&E for a couple of heart attacks. I survived those, and am now waiting for surgery to improve my outlook. However, during the episodes, my bgl rocketed up into the stratosphere (32+) and my diabetic meds were stopped by the consultant. When I returned back to nearer the ground, I was told my Glic was possibly responsible for my heart failure, and that the drug is contraindicated from now on for me. I am having to get by on metformin and not much else seeing as I am still having to eat hospital food. They will not re-instate my Glic and are saying that the only drug I can take with my dicky ticker is an SGLT-2 Inhibitor, which I have immediately refused due to its reported side effects being unacceptable for me. I have tried to find out why my consultant has banned Glic from my future, and all I can find is a small study report in the AHA Journal that shows a weak association (0.35% increase in CVE) for those taking Glic alone, but no significant risk if Glic is taken with Metformin which is what I was taking before the excitement began. Does anyone have any info on this contraindication, since it is something that is not so far in the prescribing guidelines that I can see (NICE, BNF etc)so we may need to raise this as a new warning. Edit to add: The Consultant who stopped my meds did it because I no longer need it. He confirms there is no contraindication or association between Gliclazide and heart failure currently in place, and that if I find I need something in future, then I can ask my GP. Studies I have posted in this thread show that Glic may have a protective effect for CVE and may help reduce mortality. I have answered my own question, Thank you.
