Hi. I am 65, 75KG, 175 cm, type 2 diabetic for 15 years. I have managed my fasting sugar levels to be between 4 and 6 for at least 8 years. I am suddenly very confused about Diamicron varieties and dosage. I remember taking the same diabetic medication for years, being Diabex 1000mg and Diamicron 80 mg, 1 tablet each twice daily, morning and evening. Now suddenly something called Diamicron MR 60 mg has been prescribed to me, to be taken only half a tablet twice a day! My fasting sugar levels have now risen to be between 6.5 and 8. What is this new Diamicron? Can I not still take what I have always taken? And if I must take Diamicron MR should I take 80mg or double the dosage?
