2.1 Dosage Considerations
When given subcutaneously, HUMALOG has a more rapid onset of action and a shorter duration of action than regular human insulin.
The dosage of HUMALOG must be individualized. Blood glucose monitoring is essential in all patients receiving insulin therapy.
The total daily insulin requirement may vary and is usually between 0.5 to 1 unit/kg/day. Insulin requirements may be altered during stress, major illness, or with changes in exercise, meal patterns, or coadministered drugs.
2.2 Subcutaneous Administration
HUMALOG should be given within 15 minutes before a meal or immediately after a meal.
HUMALOG given by subcutaneous injection should generally be used in regimens with an intermediate- or long-acting insulin.
HUMALOG administered by subcutaneous injection should be given in the abdominal wall, thigh, upper arm, or buttocks. Injection sites should be rotated within the same region (abdomen, thigh, upper arm, or buttocks) from one injection to the next to reduce the risk of lipodystrophy [see Adverse Reactions (6.1)].
2.3 Continuous Subcutaneous Infusion (Insulin Pump)
HUMALOG may be administered by continuous subcutaneous infusion by an external insulin pump. Do not use diluted or mixed insulins in external insulin pumps. Infusion sites should be rotated within the same region to reduce the risk of lipodystrophy [see Adverse Reactions (6.1)]. Change the HUMALOG in the reservoir at least every 7 days, change the infusion sets and the infusion set insertion site at least every 3 days.
The initial programming of the external insulin infusion pump should be based on the total daily insulin dose of the previous regimen. Although there is significant variability among patients, approximately 50% of the total dose is usually given as meal-related boluses of HUMALOG and the remainder is given as a basal infusion. HUMALOG is recommended for use in pump systems suitable for insulin infusion such as MiniMed, Disetronic, and other equivalent pumps [see For Patients Using Continuous Subcutaneous Insulin Pumps (17.2)].
