DS used to receive 14u of Lantus at bedtime, but due to repeated lows at 3:00 a.m., endo suggested splitting the dose. Currently he receives 10u at 9:00 pm and 5u at 8:00 am. So, he is currently receiving 15u/day. We also just switched to the Lantus pen which I'm not crazy about, fair amount of leakage. He is now high during school hours. I'm waiting for a call back from his endo for guidance, but if you split a Lantus dose; have you had better results with an even 50/50 split, 75/25, etc.? Thanks for any advice.
