How do I use my ICR to work out my bolus?
1 . Work out how much carbohydrate is in your meal or snack.
2 . Divide the weight of carbohydrate in your meal or snack by the weight of carbohydrate in your
ICR and multiply this by the units of insulin in your ICR.
If your meal has 40g of carbohydrate and your ICR is 1:10, you should have 4 units of bolus
insulin.
(40 ÷ 10) x 1= 4 units of insulin
If your meal has 60g of carbohydrate and your ICR is 1:7.5 (or 2:15), you should have 8 units of
bolus insulin.
(60 ÷ 7.5) x 1 = 8 units of insulin
((60 ÷ 15) x 2 = 8 units of insulin)
Look at the example below.
M e a l C a r b o h y d r a t e I C R C a l c u l a t i o n B o l u s
B r e a k f a s t 5 0 g 1 : 1 0 (50 ÷ 10) x 1 = 5 5
L u n c h 6 0 g 1 : 1 5 (60 ÷ 15) x 1 = 4 4
D i n n e r 9 0 g 1 : 1 5 (90 ÷ 15) x 1 = 6 6
Now try and work it out for some of your own meals in the table below:
