Question from Rome, Italy:
My 13 year old daughter, who has had type 1 diabetes for about two and a half years, is using Lantus as basal insulin, with NovoRapid for her meals. We give her Lantus at 8:00 pm so I can control her blood sugar at 11pm (when Lantus starts working) and give her 1 unit of NovoRapid if she is over 150 mg/dl [8.3 mmol/L] or 2 units if she is over 200 mg/dl [11.1 mmol/L]. We control her wake-up blood sugar quite well, and she is doing well till 5:00 pm when her blood sugar rises suddenly to over 200 mg/dl [11.1 mmol/L] which means that the Lantus is working just 18-20 hours. To cover the “insulin-hole” she gets a snack with a shot of NovoRapid. Her endocrinologist suggested to give her the longer lasting Actrapid for lunch to avoid another shot at 5:00 pm, but everything I read says that Lantus has to be used with NovoRapid so I wonder how to solve that problem.
Answer:
Your daughter would greatly benefit from a mid-afternoon small (1-2 units) injection of any fast-acting insulin with no snack unless she needs it. This is a very good approach aimed to fill the basal rate gap that occurs late in the afternoon and causes the rise of blood sugar. The endocrinologist’s advice of your is also a good one, and it’s worth a try because the Actrapid (Regular) lasts longer than analogs and may control the mid-afternoon rise better thus avoiding the 5:00 pm shot. In my experience, your daughter might also greatly benefit in terms of blood sugar stability from a later (bedtime) injection of the Lantus (insulin glargine) perhaps at a larger dose for a more stable plateau over the 24 hour period.

[Editor’s comment: I am unaware of any recommendation from Aventis about what short-acting insulin should be used with Lantus.
