Type 1 Insulin amount

[Strachan1]

Doing the carb and insulin counting myself, just started. I do my carb counting at evening meal, inject Novorapid which lasts 4 hrs. Then two hours later I want a snack over 15g. What should I do now to correct the carbs for this?

Hi. Assuming you dosed the 'correct' amount for the evening meal then any dose for a later additional meal/snack should follow the normal Bolus ratio calculation. As you may know you shouldn't inject more insulin as a correction dose until safely outside the Bolus time of around 4-5 hours, but when you have more food then follow the normal rules.
