It is important to transition to your newly prescribed Cyblex 80 (gliclazide) as advised by your doctor, rather than continuing Cyblex M 80. Cyblex M 80 contains two medicines, gliclazide and metformin, while Cyblex 80 contains only gliclazide. Taking both together could lower your blood sugar too much. Please start your new Cyblex 80 prescription and stop the Cyblex M 80. Since this change removes metformin from your routine, I gently encourage you to double-check with your doctor to ensure this was the intended change for your care.
