Doctor,
My dad aged 73 has been taking insulin for about 15 years now. Recently, since his Hba1C was found to be 8.4 and mean blood sugar in 6 months was found to be 240mg, he was advised to switch to the following medicines - Trivolib 2 in the morning and Jalra 50 at night. However, his blood sugar seems to be much higher than when he was taking 15 units of ActRapid before Breakfast and another 15 units before lunch, and 15 units of Human Mixtard before dinner. Is Insulin the best course for him at this stage?
