Ensure that it has been at least 90 minutes since the last injection of fast acting insulin.


Give a correction injection of fast acting insulin, using your bolus calculator to  calculate the insulin dose.

If the bolus calculator does not recommend a correction, re-check in 1 hour and then give a correction if advised by the bolus calculator.


Check glucose level 2 hours after this bolus dose has been given.

If glucose level is lower than the previous value, no further action is required.

If glucose level is the same as, or higher than the previous value, give another correction if advised by the bolus calculator.
