Usual Adult Dose for Diabetes Type 1

Individualize dose based on metabolic needs and frequent monitoring of blood glucose
-Total daily insulin requirements are generally between 0.5 to 1 unit/kg/day
-Use HbA1c values to guide therapy; consult current guidelines for optimal target ranges

Multiple-dose injection (MDI):
-Administer subcutaneously within 15 minutes of a meal or immediately after a meal
-Match prandial insulin dose to carbohydrate intake, pre-meal blood glucose, and anticipated activity
-Use in combination with an intermediate-acting or long-acting basal insulin

Continuous Subcutaneous Infusion (Insulin Pump)
-Initial programming should be based on the total daily insulin dose of previous MDI regimen; check with pump labeling to ensure the pump has been evaluated with this insulin
-While there is significant interpatient variability, approximately 50% of the total dose is provided as meal-related boluses and the remainder as a basal infusion

Intravenous Administration
-Dilute to a concentration of 0.1 to 1 unit/mL in normal saline; closely monitor blood glucose and serum potassium during administration

Use: To improve glycemic control in adult patients with diabetes mellitus.

Renal Dose Adjustments

Use with caution; frequent glucose monitoring and insulin dose adjustments may be required

Liver Dose Adjustments

Use with caution; frequent glucose monitoring and insulin dose adjustments may be required

Dose Adjustments

-Daily insulin requirements may be higher during illness, stress, pregnancy, in obese patients, trauma, during concurrent use with medications having hyperglycemic effects, or after surgery
-Daily insulin requirements may be lower with exercise, weight loss, calorie restricted diets, or during concurrent use of medications having hypoglycemic effects.

Supplemental doses may be prescribed during illness
Patients with type 2 diabetes receiving oral medications may be switched to insulin therapy temporarily.

Dosage adjustments may be required when the brand, type, or species of insulin is changed; oral antidiabetic treatment may need to be adjusted as well.

Precautions

Safety and efficacy have not been established in patients younger than 3 years.

Safety and efficacy in patients with type 2 diabetes have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.

Other Comments

Administration advice:
-May be administered IV or subcutaneously
-Never share an insulin pen between patients, even if the needle is changed; do not reuse or share needles or syringes between patients as this presents a risk for transmission of blood-borne pathogens

Multiple-dose injections:
-Administer subcutaneously into the abdomen, buttocks, thigh, or upper arm within 15 minutes before a meal or immediately after a meal.
-Rotate injection sites within same region to reduce the risk of lipodystrophy
-Ensure patients have been educated as to proper injection technique
-If needed, Humalog(R) may be diluted with Insulin Diluting Medium for Humalog to provide concentrations of U-10 or U-50: a dilution of 1 part Humalog(R) to 9 parts diluent results in a U-10 concentration, a dilution of 1 part Humalog(R) to 1 part diluent results in a U-50 concentration.
-Humalog(R) may be mixed with NPH insulin; draw Humalog(R) into syringe first and administer immediately after mixing.

Continuous Subcutaneous Infusion (Insulin pump)
-Infusion sets should be inserted into the subcutaneous fat layer of the abdominal wall; rotate sites to avoid lipodystrophy
-Do not use diluted, intermediate-acting, long-acting or mixed insulins in insulin pumps
-Check pump labeling to ensure the pump has been evaluated with insulin lispro
-Insulin lispro in the reservoir should be changed at least every 7 days; infusion sets and insertion site should be changed at least every 3 days
-Remind patients on insulin pump therapy that they must have an alternative insulin delivery system available in case of pump system failure.

Intravenous:
-Administer by IV infusion at a concentration of 0.1 to 1 unit/mL in normal saline under medical supervision
-Closely monitor glucose and serum potassium
-Insulin mixtures should not be administered intravenously

Storage requirements:
-Unopened: Store in refrigerator 2C to 8C (36F to 46F); do not freeze, discard if frozen
-Open (in-use) Cartridge Systems, Pens, and Vials: Store below 30C (86F); use within 28 days; protect from direct heat and light

Diluted Humalog(R):
-Concentrations of U-10 or U-50 when prepared with insulin diluting medium may be used for up to 28 days when stored below 5C (41F) OR for 14 days when stored at 30C (86F)

Infusion Fluids:
-Infusion bags when mixed in normal saline and refrigerated (2C to 8C [36F to 46F]) are stable for 48 hours, and then may be used at room temperature for up to an additional 48 hours.

Pump:
-Discard insulin in pump reservoir after 7 days or after exposure to temperatures that exceed 37C (98.6F)

Reconstitution/preparation techniques:
-Insulin Pens and Cartridge Systems: The manufacturer product information should be consulted.
-To avoid contamination, pens should be used by a single patient only: always remove needle from delivery device after use and store pens without a needle attached; always use a new needle for each injection.

-For IV infusion : Dilute to a concentration of 0.05 to 1 unit/mL in normal saline in infusion systems using polypropylene infusion bags; stable in 0.9% sodium chloride at room temperature for 24 hours.

General:
-Insulin requirements may be altered during stress, major illness, or with changes in exercise, meal patterns, or coadministered drugs; duration of action of this insulin will vary according to dose, injection site, blood flow, temperature, and level of physical activity.
-This insulin is a rapid-acting insulin analog that is equipotent to human insulin when administered IV; when administered subcutaneously, it has a more rapid onset of action and a shorter duration of action.
-Rapid acting insulin analogs are superior to regular insulin when administered subcutaneously because they are more predictable.
-Hypoglycemia is the most common adverse reaction of insulin therapy; the timing generally reflects the time-action profile of the administered insulin.

Monitoring:
-Blood glucose monitoring is essential for patients receiving insulin therapy.
-Closely monitor blood glucose and potassium in patients receiving IV insulin.
-Urine ketone testing is recommended for patients with type I diabetes if they develop symptoms of colds, influenza, nausea, vomiting, or other illnesses, polyuria, or if blood glucose levels are unexpectedly high or inconsistent.
-Glycosylated hemoglobin measurements are recommended every 3 months.

Patient advice:
-Patients should be advised to never share an insulin pen with another person, even if the needle is changed; patients should understand that sharing needles or syringes with another person carries a risk for transmission of blood-borne pathogens.
-Patients should be instructed on glucose monitoring, proper injection technique, and the management of hypoglycemia and hyperglycemia.
-Patients should be instructed on how to handle situations which may affect their insulin requirements.
-Remind patients to check insulin labels before injection to avoid medication errors.
-Patients should check blood sugar prior to driving a car or operating machinery.
-Advise patient to speak to physician or health care professional if pregnant or if they intend to become pregnant.
