  • Enter your present BS & target BS, select the unit (mmol/l or mg/dl), click "calculate BS correction" to get BS correction insulin and proceed further by pressing Next (total meal time insulin).

You need to adjust your daily dose of insulin

Insulin dose adjustment has based on the TDD (total daily dose of insulin) you received in the preceding 24 hours.

  • If your BS at any time is less than 80 mg/dl; you need to reduce your TDD to 80% of yesterday’s TDD insulin dosage.
  • If your BS at any time is greater than 180 mg/dl, and none of the BS numbers are less than 80 mg/dl; you need to increase 110 % of yesterday’s TDD insulin dosage.
  • Other considerations: You may only adjust specific parts of your dosing based on highs or lows. If your dinner blood sugar is high, increase your meal insulin given at lunch. If bedtime is high, increase your meal insulin given at dinner, etc.
