In my opinion you are giving him higher dose of Lanctus than required. I would suggest you to decease the dose 2 units daily initially then 1 unit daily and measure the blood sugar level before and after every meal TILL THE DESIRED LEVEL IS reached that is 90 to 120 fasting and 120 to 150 postprandial . WARNING keep it on little higher side of normal value otherwise he may go in to hypoglycemia. If results are unsatisfactory see your doctor he may like to change the drug itself.
