A medical device and method for determining a dose of insulin to be administered for glycemic control is provided, wherein the dose is stepwise adapted, comprising determining a blood glucose value, receiving glycemic event information in respect to a predetermined glycemic event, wherein the predetermined glycemic event occurred within a predetermined time interval, receiving a previously adapted dose value stored in a storage unit, and setting an alert based on at least the blood glucose value, the glycemic event information and the previously adapted dose, wherein the alert indicates that the blood glucose value and the predetermined glycemic event are not in a specified relation to the previously adapted dose value.
