Note: Insulin aspart is a rapid-acting insulin analog available in a conventional formulation (eg, NovoLOG, NovoRapid [Canadian product]) and a faster-acting formulation (Fiasp), which differ in onset of action and administration instructions (Heise 2017; Matthieu 2018). These products are not interchangeable (ISMP 2019). Insulin requirements vary dramatically between patients and dictate frequent monitoring and close medical supervision. In Canada, Trurapi is approved as a biosimilar to NovoRapid.
Diabetes mellitus, type 1, treatment:
Note: Insulin aspart must be used concomitantly with intermediate- or long-acting insulin (ie, multiple daily injection regimen) or in a continuous subcutaneous insulin infusion device. The total daily doses (TDD) presented below are expressed as the total units/kg/day of all insulin formulations combined.
General insulin dosing:
Initial TDD: SUBQ: ~0.4 to 0.5 units/kg/day; conservative initial doses of 0.2 to 0.4 units/kg/day may be considered to avoid the potential for hypoglycemia; higher initial doses may be required in patients who are obese, sedentary or presenting with ketoacidosis (AACE/ACE [Handelsman 2015]; ADA 2021).
Usual TDD maintenance range: SUBQ: 0.4 to 1 units/kg/day in divided doses (ADA 2021).
Division of TDD (multiple daily injections):
Basal insulin: Generally, 40% to 50% of the TDD is given as basal insulin (intermediate- or long-acting) in 1 to 2 daily injections (AACE/ACE [Handelsman 2015]; ADA 2021).
Prandial insulin: The remaining portion (ie, 50% to 60%) of the TDD is then divided and administered before, at, or just after mealtimes depending on the formulation (eg, short-, rapid-, ultra-rapid acting) (AACE/ACE [Handelsman 2015]; ADA 2021).
Dosage adjustment: Dosage must be titrated to achieve glucose control and avoid hypoglycemia. Adjust dose to maintain premeal and bedtime glucose in target range. Since combinations of agents are frequently used, dosage adjustment must address the individual component of the insulin regimen which most directly influences the blood glucose value in question, based on the known onset and duration of the insulin component.
Diabetes mellitus, type 2, treatment:
Initial: SUBQ: 4 to 5 units or 10% of the basal insulin dose administered before the largest meal of the day (AACE/ACE [Garber 2020]; ADA 2021).
Note: Stepwise addition of prandial insulin starting with a single meal and progressing to 2 or more meals as needed every 3 months is associated with a lower risk of hypoglycemia and increased patient satisfaction compared with immediate introduction of a full basal-bolus regimen. Insulin aspart (ie, a rapid-acting insulin) is usually given in addition to a regimen that includes basal insulin (ie, a long-acting insulin such as glargine, degludec, or detemir; or an intermediate-acting insulin such as NPH) and metformin +/- other noninsulin agents. Consider reducing the total daily dose by 4 units or 10% of the basal insulin dose if HbA1c is <8% when initiating prandial insulin (AACE/ACE [Garber 2020]; ADA 2021).
Dosage adjustment:
To reach self-monitoring glucose target: SUBQ: Adjust dose by 10% to 15% or 1 to 2 units twice weekly (ADA 2021).
For hypoglycemia: SUBQ: If no clear reason for hypoglycemia, decrease dose by 10% to 20%; for hypoglycemia requiring assistance from another person or blood glucose <40 mg/dL, reduce dose by 20% to 40% (AACE/ACE [Garber 2020]; ADA 2021).
HbA1c still not controlled despite titrations to reach glycemic targets:One option is to advance to ‘basal-bolus’ (ie, insulin aspart administered before each meal) in addition to basal insulin and usually given in addition to metformin +/- other noninsulin agents (AACE/ACE [Garber 2020]; ADA 2021).
Patients with diabetes receiving enteral feedings: Note: TDD of insulin is divided into a basal component (intermediate- or long-acting insulin) and nutritional and correctional components (regular insulin or rapid-acting insulins).
Nutritional: SUBQ: 1 unit of insulin aspart per 10 to 15 g of carbohydrate prior to each bolus feeding; in patients receiving continuous feeds, administer every 4 hours based on the amount of carbohydrate administered over each 4-hour period (ADA 2021; ES [Umpierrez 2012]).
Correctional: SUBQ: Administer correctional insulin as needed prior to each feeding (for bolus feeds) or every 4 hours (for continuous feeds) (ADA 2021). Dosing is individualized; one example of an empiric correctional dose is 1 to 2 units per 40 to 50 mg/dL above target glucose level; patients with known insulin resistance or who are receiving glucocorticoids may require higher correctional doses (eg, 4 units per 50 mg/dL above target glucose level) (Clement 2004; ES [Umpierrez 2012]; Gianchandani 2020; Inzucchi 2011; Magaji 2011).
Patients with diabetes undergoing surgery and using an insulin pump: SUBQ: For short procedures (eg, <2 hours), continue the usual pump "basal" insulin infusion rate, with or without a temporary 20% to 40% rate reduction, on the morning of the procedure. For long and complex procedures, consider transitioning from the insulin pump to an IV regular insulin infusion perioperatively (ADA 2021; Leung 2017).
Diabetic ketoacidosis, mild to moderate, uncomplicated (alternative agent) (off-label use):
Note: SUBQ insulin aspart may be used as an alternative to IV regular insulin in patients in whom management of diabetic ketoacidosis (DKA) outside of a critical care area is appropriate; faster-acting insulin aspart products (eg, Fiasp) have not been evaluated for this purpose. IV regular insulin (preferred over IV rapid-acting insulin analogs) should be used in patients with severe DKA, evidence of hyperosmolar hyperglycemic state (eg, altered mental status), persistent hypotension, or other critical illness, as well as during pregnancy (Cardoso 2017; Kitabchi 2009; Umpierrez 2004). Begin correction of fluid deficits, if present. If serum potassium is <3.3 mEq/L on initial presentation, delay insulin administration until serum potassium reaches ≥3.3 mEq/L. Address other electrolyte abnormalities, as needed, during insulin administration (Kitabchi 2009). In patients with initial serum glucose <250 mg/dL, initiate dextrose-containing IV fluids at the time of insulin initiation (Rawla 2017). An example of a dosing regimen is as follows; refer to institutional protocols:
1-hour interval dosing: SUBQ: Initial: 0.3 units/kg, followed by 0.1 units/kg every hour until blood glucose <250 mg/dL, then decrease to 0.05 units/kg every hour until resolution of ketoacidosis (Umpierrez 2004). May increase dose (eg, by double) if serum glucose does not decrease by ~50 to 75 mg/dL in the first hour (Hirsch 2021; Kitabchi 2009).
2-hour interval dosing: SUBQ: Initial: 0.3 units/kg, followed by 0.2 units/kg 1 hour later and then every 2 hours thereafter until blood glucose <250 mg/dL, then decrease to 0.1 units/kg every 2 hours until resolution of ketoacidosis (Umpierrez 2004). May increase dose (eg, by double) if serum glucose does not decrease by ~50 to 75 mg/dL in the first hour (Hirsch 2021; Kitabchi 2009).
Hyperglycemia, hospitalized patients (off-label use):
Note: For use in patients with persistent hyperglycemia (eg, blood glucose ≥140 to 180 mg/dL for >12 to 24 hours) with or without a history of diabetes; use of institution-specific protocols to achieve glycemic targets and minimize hypoglycemia is encouraged (ADA 2021; ES [Umpierrez 2012]; SCCM [Jacobi 2012]).
Correctional insulin:
Note: For use in addition to scheduled basal and nutritional insulin to achieve glycemic targets; prolonged use of correctional insulin without basal insulin is discouraged (ADA 2021; ADA/AACE [Moghissi 2009]).
SUBQ: Refer to institution-specific protocols; one example of an empiric correctional dose is 1 to 2 units per 40 to 50 mg/dL above target glucose level; dose is typically administered with meals (or bolus feeds) or every 4 hours (if NPO or receiving continuous feeds); patients with known insulin resistance or who are receiving glucocorticoids may require higher correctional doses (eg, 4 units per 50 mg/dL above target glucose level) (ADA 2021; Clement 2004; ES [Umpierrez 2012]; Gianchandani 2020; Inzucchi 2011; Magaji 2011).
Nutritional insulin:
Initial daily dosage:
Patients not receiving nutritional insulin prior to hospitalization:
Patients eating meals:
SUBQ: 0.03 to 0.1 units/kg/meal administered with or just after meals (ADA 2021; ES [Umpierrez 2012]). Note: Dose is individualized; consider doses at the lower end of this range in older patients and in those with renal impairment; consider doses at the higher end of this range in patients receiving glucocorticoids (ES [Umpierrez 2012]).
Patients receiving enteral feeds:
SUBQ: 1 unit of insulin aspart per 10 to 15 g of carbohydrate prior to each bolus feeding; in patients receiving continuous feeds, administer every 4 hours based on the amount of carbohydrate administered over each 4-hour period (ADA 2021; ES [Umpierrez 2012]).
Patients receiving nutritional insulin prior to hospitalization:
SUBQ: Continue the prehospitalization nutritional insulin dose; an empiric 25% to 50% dose reduction may be considered in patients with impaired renal function, poor nutritional intake, or admission glucose levels <100 mg/dL; higher doses may be required in patients receiving glucocorticoids (ADA 2021; ES [Umpierrez 2012]; Inzucchi 2011).
Dosage adjustment: Adjust daily dose by 10% to 20% every 2 to 3 days to achieve glycemic targets. Consider reducing dosage for glucose levels <100 mg/dL to avoid hypoglycemia; in patients with glucose levels <40 mg/dL, larger dose reductions (eg, by 20% to 40%) may be needed (AACE/ACE [Garber 2020]; ADA/AACE [Moghissi 2009]).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in the manufacturer's labeling; however, dosage adjustments may be needed. Renal impairment may change insulin requirements; monitor blood glucose closely.
There are no dosage adjustments provided in the manufacturer's labeling; however, dosage adjustments may be needed. Hepatic impairment may change insulin requirements; monitor blood glucose closely.
(For additional information see "Insulin aspart (including biosimilars available in Canada): Pediatric drug information")
Insulin aspart is a rapid-acting insulin analog available in a conventional formulation (eg, NovoLog, NovoRapid [Canadian product]) and a faster-acting formulation (Fiasp), which differ in onset of action and administration instructions and risk of hypoglycemic episodes. These products are not interchangeable (ISMP 2019).
Insulin doses should be individualized based on patient needs; adjustments may be necessary with changes in physical activity, meal patterns, acute illness, or with changes in renal or hepatic function. Insulin requirements vary dramatically between patients and dictates frequent monitoring and close medical supervision. Insulin regimens vary widely by region, practice, and institution; consult institution-specific guidelines.
Type 1 diabetes mellitus: Infants, Children, and Adolescents: Note: Insulin aspart must be used concomitantly with intermediate- or long-acting insulin (ie, multiple daily injection regimen) or in a continuous subcutaneous infusion pump. The daily doses presented are expressed as the total units/kg/day of all insulin formulations combined.
General insulin dosing:
Initial total daily insulin: SubQ: Initial: 0.4 to 0.5 units/kg/day in divided doses (AACE/ACE [Handelsman 2015]; ADA 2020); usual range: 0.4 to 1 units/kg/day in divided doses (AACE/ACE [Handelsman 2015]; ADA 2020; Silverstein 2005); lower doses (0.25 units/kg/day) may be used, especially in young children, to avoid potential hypoglycemia (Beck 2015); higher doses may be necessary for some patients (eg, obese, concomitant steroids, puberty, sedentary lifestyle, following diabetic ketoacidosis presentation) (AACE/ACE [Handelsman 2015]; ADA 2020; Silverstein 2005).
Usual total daily maintenance range: SubQ: Doses must be individualized; however, an estimate can be determined based on phase of diabetes and level of maturity (ISPAD [Danne 2018]; ISPAD [Sundberg 2017]).
Partial remission phase (Honeymoon phase): <0.5 units/kg/day.
Prepubertal children (not in partial remission):
Infants ≥6 months and Children ≤6 years: 0.4 to 0.8 units/kg/day.
Children ≥7 years: 0.7 to 1 units/kg/day.
Pubescent Children and Adolescents: During puberty, requirements may substantially increase to >1 unit/kg/day and in some cases up to 2 units/kg/day.
Division of daily insulin requirement (multiple daily injections):
Basal insulin: Generally, ~30% to 50% of the total daily insulin is given as basal insulin (intermediate- or long-acting) in 1 to 2 daily injections (AACE/ACE [Handelsman 2015]; ADA 2020; ISPAD [Danne 2018]; Peters 2013).
Prandial insulin: The remaining portion of the total daily dose is then divided and administered before or at mealtimes (depending on the formulation) as a rapid-acting (eg, aspart, glulisine, lispro) or short-acting (regular). In most type 1 patients, the use of a rapid-acting insulin analog is preferred over regular insulin to reduce hypoglycemia risk (AACE/ACE [Handelsman 2015]; ADA 2020; ADA [Chiang 2014]; ISPAD [Danne 2018]).
Dosage titration: Treatment and monitoring regimens must be individualized to maintain premeal and bedtime glucose in target range; titrate dose to achieve glucose control and avoid hypoglycemia. Since combinations of agents are frequently used, dosage adjustment must address the individual component of the insulin regimen which most directly influences the blood glucose value in question, based on the known onset and duration of the insulin component.
Diabetic ketoacidosis, uncomplicated: Limited data available: Infants, Children, and Adolescents: SubQ: 0.15 units/kg/dose every 2 to 3 hours until resolution of metabolic acidosis (ISPAD [Wolfsdorf 2018]; Razavi 2018; Savoldelli 2010); if serum glucose decreases by >100 mg/dL/hour, reduce dose to 0.1 units/kg/dose (Savoldelli 2010).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in manufacturer's labeling; insulin requirements are reduced due to changes in insulin clearance or metabolism; monitor blood glucose closely.

SUBQ administration: Cold injections should be avoided. SUBQ administration is usually made into the thighs, arms, or abdomen; NovoLOG may also be administered in the buttocks. Rotate injection sites within the same region to avoid lipodystrophy or localized cutaneous amyloidosis. Rotating from an injection site where lipodystrophy/cutaneous amyloidosis is present to an unaffected site may increase risk of hypoglycemia. For prefilled pen injectors, prime the needle before each injection with 2 units of insulin. Once injected, hold the pen device in the skin for a count of 6 after the dose dial has returned to 0 units before the needle is removed to ensure the full dose has been administered.
Fiasp: Inject at the beginning of or within 20 minutes after starting a meal. Do not mix with any other insulin products or solutions. Fiasp FlexTouch is designed to dial doses in 1-unit increments.
NovoLOG: Administer immediately (within 5 to 10 minutes) before a meal. NovoLOG from a vial may be mixed with insulin NPH only (do not mix with other types of insulin) but should be drawn into syringe first. Do not dilute or mix other insulin formulations with NovoLOG contained in a cartridge or prefilled pen. NovoLOG FlexPen and FlexTouch are designed to dial doses in 1-unit increments.
Continuous subcutaneous insulin infusion administration: Patients should be trained in the proper use of their external insulin pump and in intensive insulin therapy. Infusion sets and infusion set insertion sites should be changed at least every 3 days; rotate infusion sites. Insulin in reservoir should be changed at least every 6 days or according to continuous subcutaneous insulin infusion device user manual (whichever is shorter). Do not dilute or mix other insulin formulations with insulin aspart that is to be used in an external insulin pump.
IV administration: May be administered IV with close monitoring of blood glucose and serum potassium; appropriate medical supervision is required. Do not administer insulin mixtures intravenously.
IV infusions: To minimize insulin adsorption to plastic IV tubing: Although data is lacking regarding adsorption with insulin aspart, insulin regular loss has been shown to occur by adsorption to plastic (ie, polyvinyl chloride, polyethylene, polyolefin, polypropylene) IV containers and tubing (Greenwood 2012; Hirsch 1977; Hirsch 1981; Rocchio 2013; Thompson 2012). Therefore, flush the IV tubing with a priming infusion of 20 mL from the insulin infusion, whenever a new IV tubing set is added to the insulin infusion container (SCCM [Jacobi 2012]; Thompson 2012).
Note: Also refer to institution-specific protocols where appropriate.
Because of insulin adsorption to plastic IV tubing or infusion bags, the actual amount of insulin being administered via IV infusion could be substantially less than the apparent amount. Therefore, adjustment of the IV infusion rate should be based on effect and not solely on the apparent insulin dose. The apparent dose may be used as a starting point for determining the subsequent SUBQ dosing regimen (Moghissi 2009); however, the transition to SUBQ administration requires continuous medical supervision, frequent monitoring of blood glucose, and careful adjustment of therapy. In addition, SUBQ insulin should be given 1 to 4 hours prior to the discontinuation of IV insulin to prevent hyperglycemia (Moghissi 2009).
Note: Fiasp and NovoLog products are not interchangeable (ISMP 2019).
Parenteral: Do not use if solution is viscous or cloudy; use only if clear and colorless with no visible particles.
SubQ: Avoid cold injections. Administer into the subcutaneous fat of the thighs, arms, or abdomen; NovoLog may also be administered in the buttocks. Rotate injection sites within the same region to reduce the risk of lipodystrophy or localized cutaneous amyloidosis. Rotating from an injection site where lipodystrophy/cutaneous amyloidosis is present to an unaffected site may increase risk of hypoglycemia. For prefilled pen injectors, prime the needle before each injection with 2 units of insulin (use a new needle for each injection); see manufacturer's labeling for specific procedure. Once primed, set dial to the appropriate dose, insert needle into clean skin, and activate device by holding the button down; continue to hold the button until the dose dial has returned to 0 units. After the insulin is injected, hold the needle in the skin for a count of 6 after the dose dial has returned to 0 units to ensure the full dose has been administered. Do not rub the area.
Fiasp: Inject at the beginning of or within 20 minutes after starting a meal. Do not mix with any other insulin products or solutions. Fiasp FlexTouch is designed to dial doses in 1-unit increments.
NovoLog: Administer immediately (within 5 to 10 minutes) before meals. NovoLog from a vial may be mixed in the same syringe with NPH insulin; do not mix with other types of insulin. When mixing NovoLog with NPH insulin, NovoLog should be drawn into the syringe first. Do not dilute or mix other insulin formulations with NovoLog contained in a cartridge or prefilled pen. NovoLog FlexPen and FlexTouch are designed to dial doses in 1-unit increments.
Continuous SubQ insulin infusion (insulin pump): Do not use if solution is viscous or cloudy; use only if clear and colorless. Patients should be trained in the proper use of their external insulin pump and in intensive insulin therapy. Infusion sets and infusion set insertion sites should be changed at least every 3 days; rotate infusion sites. Insulin in reservoir should be changed at least every 6 days or according to continuous subcutaneous insulin infusion device use manual (whichever is shorter). Do not dilute or mix other insulin formulations with insulin aspart that is to be used in an external insulin pump.
IV: Insulin aspart may be administered IV in selected clinical situations to control hyperglycemia. Closely monitor blood glucose and serum potassium; appropriate medical supervision is required. Do not administer insulin mixtures intravenously.
To minimize insulin adsorption to IV tubing: Flush the IV tubing with a priming infusion of 20 mL from the insulin infusion, whenever a new IV tubing set is added to the insulin infusion container (Jacobi 2012; Thompson 2012). Also refer to institution-specific protocols where appropriate.

The Institute for Safe Medication Practices includes this medication among its list of drugs which have a heightened risk of causing significant patient harm when used in error. Due to the number of insulin preparations, it is essential to identify/clarify the type of insulin to be used.
Beers Criteria: Insulin (short- or rapid-acting insulin products used for sliding scale), is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older (independent of diagnosis or condition) due to higher risk of hypoglycemia associated with sliding scale insulin without improvements in hyperglycemia, regardless of care setting. Avoid insulin regimens that only use short- or rapid-acting insulins dosed based on current blood glucose levels in the absence of basal or long-acting insulin; recommendation does not apply to regimens containing basal or long-acting insulin (Beers Criteria [AGS 2019]).
Cross-contamination may occur if insulin pens are shared among multiple patients. Steps should be taken to prohibit sharing of insulin pens.
NovoLOG and Fiasp are not interchangeable; onset of action and timing of administration with respect to meals varies between products.

Hypersensitivity to insulin aspart or any component of the formulation; during episodes of hypoglycemia
Concerns related to adverse effects:
• Glycemic control: Hyper- or hypoglycemia may result from changes in insulin strength, manufacturer, type, and/or administration method. The most common adverse effect of insulin is hypoglycemia. The timing of hypoglycemia differs among various insulin formulations. Hypoglycemia may result from changes in meal pattern (eg, macronutrient content, timing of meals), changes in the level of physical activity, increased work or exercise without eating, or changes to coadministered medications. Use of long-acting insulin preparations (eg, insulin degludec, insulin detemir, insulin glargine) may delay recovery from hypoglycemia. Patients with renal or hepatic impairment may be at a higher risk. Symptoms differ in patients and may change over time in the same patient; awareness may be less pronounced in those with long-standing diabetes, diabetic nerve disease, patients taking beta-blockers, or in those who experience recurrent hypoglycemia. Profound and prolonged episodes of hypoglycemia may result in convulsions, unconsciousness, temporary or permanent brain damage, or even death. Insulin requirements may be altered during illness, emotional disturbances, or other stressors. Instruct patients to use caution with ethanol; may increase risk of hypoglycemia.
• Hypersensitivity: Hypersensitivity reactions (serious, life-threatening and anaphylaxis) have occurred. If hypersensitivity reactions occur, discontinue administration and initiate supportive care measures.
• Hypokalemia: Insulin (especially IV insulin) causes a shift of potassium from the extracellular space to the intracellular space, possibly producing hypokalemia. If left untreated, hypokalemia may result in respiratory paralysis, ventricular arrhythmia and even death. Use with caution in patients at risk for hypokalemia (eg, loop diuretic use). Monitor serum potassium frequently with IV use and supplement potassium when necessary.
Disease-related concerns:
• Bariatric surgery:
– Type 2 diabetes, hypoglycemia: Closely monitor insulin dose requirement throughout active weight loss with a goal of eliminating antidiabetic therapy or transitioning to agents without hypoglycemic potential; hypoglycemia after gastric bypass, sleeve gastrectomy, and gastric band may occur (Mechanick 2013). Insulin secretion and sensitivity may be partially or completely restored after these procedures (Korner 2009; Peterli 2012). Rates and timing of type 2 diabetes improvement and resolution vary widely by patient. Insulin dose reduction of ≥75% has been suggested after gastric bypass for patients without severe β-cell failure (fasting c-peptide <0.3 nmol/L) (Cruijsen 2014). Avoid the use of bolus insulin injections or dose conservatively with close clinical monitoring in the early phases after surgery.
– Weight gain: Insulin therapy is preferred if antidiabetic therapy is required during the perioperative period (Mechanick 2019). Evaluate risk versus benefit of long-term postoperative use and consider alternative therapy due to potential for insulin-induced weight gain (Apovian 2015).
• Cardiac disease: Concurrent use with peroxisome proliferator-activated receptor (PPAR)-gamma agonists, including thiazolidinediones, may cause dose-related fluid retention and lead to or exacerbate heart failure, particularly when used in combination with insulin. If PPAR-gamma agonists are prescribed, monitor for signs and symptoms of heart failure. If heart failure develops, consider PPAR-gamma agonist dosage reduction or therapy discontinuation.
• Hepatic impairment: Use with caution in patients with hepatic impairment. Risk of hypoglycemia may be increased; more frequent monitoring and dosage adjustments may be required.
• Renal impairment: Use with caution in patients with renal impairment. Risk of hypoglycemia may be increased; more frequent monitoring and dosage adjustments may be required.
Special populations:
• Hospitalized patients: Prolonged use of a sliding scale insulin regimen in the inpatient setting is strongly discouraged. In the critical care setting, continuous IV insulin infusion (insulin regular) has been shown to best achieve glycemic targets. In noncritically ill patients with either poor oral intake or taking nothing by mouth, basal insulin use is preferred, with correctional doses (insulin regular or rapid-acting insulin) as needed. In noncritically ill patients with adequate nutritional intake, a combination of basal insulin along with nutritional and correctional components (insulin regular or rapid-acting insulin) is preferred. An effective insulin regimen will achieve the goal glucose range without the risk of severe hypoglycemia. A blood glucose value <70 mg/dL should prompt a treatment regimen review and change, if necessary, to prevent further hypoglycemia (ADA 2021).
Dosage form specific issues:
• Multiple dose injection pens: According to the Centers for Disease Control and Prevention (CDC), pen-shaped injection devices should never be used for more than one person (even when the needle is changed) because of the risk of infection. The injection device should be clearly labeled with individual patient information to ensure that the correct pen is used (CDC 2012).
• Prefilled pen devices: Do not transfer insulin aspart from a prefilled pen to a syringe.
Other warnings/precautions:
• Continuous subcutaneous insulin infusion administration: Insulin aspart may be administered via continuous subcutaneous insulin infusion; do not dilute or mix with other insulin formulations. Rule out external pump failure if unexplained hyperglycemia or ketosis occurs; temporary SUBQ insulin administration may be required until the problem is identified and corrected.
• IV administration: Insulin aspart may be administered IV in selected clinical situations to control hyperglycemia; close monitoring of blood glucose and serum potassium as well as medical supervision is required.
• Patient education: Diabetes self-management education is essential to maximize the effectiveness of therapy.
Insulin aspart is available in a conventional formulation (NovoLog) and a faster-acting formulation (Fiasp), which differ in onset of action and administration instructions. Pediatric patients with type 1 diabetes treated with mealtime and postmeal Fiasp experience a higher incidence of hypoglycemia compared to patients treated with NovoLog, with the greatest incidence occurring overnight. Monitor glucose levels closely.

Patients with diabetes mellitus who wish to conceive should use adequate contraception until glycemic control is achieved (ADA 2021). Rapid acting insulin aspart is one of the preferred insulins for use in patients with diabetes mellitus planning to become pregnant (Blumer 2013).
Rapid-acting insulin aspart (NovoLOG) can be detected in cord blood (Pettitt 2007).
Poorly controlled diabetes during pregnancy can be associated with an increased risk of adverse maternal and fetal outcomes, including diabetic ketoacidosis, preeclampsia, spontaneous abortion, preterm delivery, delivery complications, major malformations, stillbirth, and macrosomia. To prevent adverse outcomes, prior to conception and throughout pregnancy, maternal blood glucose and HbA1c should be kept as close to target goals as possible but without causing significant hypoglycemia (ADA 2021; Blumer 2013).
Due to pregnancy-induced physiologic changes, insulin requirements tend to increase as pregnancy progresses, requiring frequent monitoring and dosage adjustments. Following delivery, insulin requirements decrease rapidly (ACOG 201 2018; ADA 2021).
Insulin is the preferred treatment of type 1 and type 2 diabetes mellitus in pregnancy, as well as gestational diabetes mellitus when pharmacologic therapy is needed (ACOG 190 2018; ACOG 201 2018; ADA 2021). Rapid-acting insulin aspart is one of the preferred insulins for use in pregnancy (ACOG 190 2018; ACOG 201 2018; Blumer 2013).
Maternal use of faster-acting insulin aspart (Fiasp) compared to rapid-acting insulin aspart (NovoLog) in pregnancy is under study (NCT03770767).
In a study using rapid-acting insulin aspart (NovoRapid), both exogenous and endogenous insulin were present in breast milk (Whitmore 2012). Insulin is not systemically absorbed via breast milk but may provide local benefits to the infant GI tract (Anderson 2018).
Appropriate glycemic control is required for the establishment of lactation in patients with diabetes mellitus (Anderson 2018). Breastfeeding provides metabolic benefits to mothers with type 1, type 2, and gestational diabetes mellitus as well as their infants; therefore, breastfeeding is encouraged (ACOG 201 2018; ADA 2021; Blumer 2013). Breastfeeding also influences maternal glucose tolerance; close monitoring of patients treated with insulin is recommended as dose adjustments may be required (ADA 2021; Anderson 2018). A small snack before breastfeeding may help decrease the risk of hypoglycemia in patients with pregestational diabetes (ACOG 201 2018; Reader 2004). According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.
Individualized medical nutrition therapy (MNT) based on ADA recommendations is an integral part of therapy.
Diabetes mellitus: Blood glucose (individualize frequency based on treatment regimen, hypoglycemia risk, and other patient-specific factors) (ADA 2021); electrolytes; renal function; hepatic function; weight.
Gestational diabetes mellitus: Blood glucose 4 times daily (1 fasting and 3 postprandial) until glycemic targets are met, then as appropriate (ACOG 2018).
Hospitalized patients: In patients who are eating, monitor blood glucose before meals and at bedtime; in patients who are not eating or are receiving continuous enteral feeds, monitor blood glucose every 4 to 6 hours (ADA 2021; ES [Umpierrez 2012]). More frequent monitoring may be required in some cases (eg, recurrent hypoglycemia, changes in nutrition, medication changes affecting glycemic control) (ES [Umpierrez 2012]).
Critically ill patients receiving an IV insulin infusion: Monitor blood glucose every 1 to 2 hours; serum potassium (ADA 2021; SCCM [Jacobi 2012]; manufacturer’s labeling). Note: Arterial or venous whole blood sampling is recommended for patients in shock, on vasopressor therapy, or with severe edema, and when on a prolonged IV insulin infusion (SCCM [Jacobi 2012]).
HbA1c: Monitor at least twice yearly in patients who have stable glycemic control and are meeting treatment goals; monitor quarterly in patients in whom treatment goals have not been met, or with therapy change. Note: In patients prone to glycemic variability (eg, patients with insulin deficiency) or in patients whose HbA1c is discordant with serum glucose levels or symptoms, consider evaluating HbA1c in combination with blood glucose levels and/or a glucose management indicator (ADA 2021; KDIGO 2020).
Diabetic ketoacidosis: Frequent monitoring (eg, every 1 to 4 hours) of serum electrolytes (eg, sodium, potassium, bicarbonate, phosphate), serum glucose, anion gap, venous pH, serum BUN, serum creatinine, serum osmolality, fluid status (eg, BP, fluid intake/output, signs/symptoms of dehydration or fluid overload), anion gap, and mental status. Refer also to institutional protocols (Hirsch 2021; Kitabchi 2009).
Recommendations for glycemic control in patients with diabetes and/or hyperglycemia:
Nonpregnant adults (ADA 2021):
HbA1c: <7% (a more aggressive [<6.5%] or less aggressive [<8%] HbA1c goal may be targeted based on patient-specific characteristics). Note: In patients using a continuous glucose monitoring system, a goal of time in range >70% with time below range <4% is recommended and is similar to a goal HbA1c <7%.
Preprandial capillary blood glucose: 80 to 130 mg/dL (more or less stringent goals may be appropriate based on patient-specific characteristics).
Peak postprandial capillary blood glucose (~1 to 2 hours after a meal): <180 mg/dL (more or less stringent goals may be appropriate based on patient-specific characteristics).
Older adults (≥65 years of age) (ADA 2021):
Note: Consider less strict targets in patients who are using insulin and/or insulin secretagogues (sulfonylureas, meglitinides) (ES [LeRoith 2019]).
HbA1c: <7% to 7.5% (healthy); <8% to 8.5% (complex/intermediate health). Note: Individualization may be appropriate based on patient and caregiver preferences and/or presence of cognitive impairment. In patients with very complex or poor health (ie, limited remaining life expectancy), consider making therapy decisions based on avoidance of hypoglycemia and symptomatic hyperglycemia rather than HbA1c level.
Preprandial capillary blood glucose: 80 to 130 mg/dL (healthy); 90 to 150 mg/dL (complex/intermediate health); 100 to 180 mg/dL (very complex/poor health).
Bedtime capillary blood glucose: 80 to 180 mg/dL (healthy); 100 to 180 mg/dL (complex/intermediate health); 110 to 200 mg/dL (very complex/poor health).
Pregnant patients:
HbA1c: Pregestational diabetes (type 1 or type 2) (ADA 2021):
Preconception (patients planning for pregnancy): <6.5%.
During pregnancy <6% (if can be achieved without significant hypoglycemia) or <7% if needed to prevent hypoglycemia.
Capillary blood glucose: Note: Less stringent targets may be appropriate if goals cannot be achieved without causing significant hypoglycemia (ADA 2021).
Gestational diabetes mellitus (ACOG 2018; ADA 2021):
Fasting: <95 mg/dL.
Postprandial: <140 mg/dL (at 1 hour) or <120 mg/dL (at 2 hours).
Pregestational diabetes mellitus (type 1 or type 2) (ADA 2021 ):
Fasting: 70 to 95 mg/dL.
Postprandial: 110 to 140 mg/dL (at 1 hour) or 100 to 120 mg/dL (at 2 hours).
Hospitalized adult patients (ADA 2021): Target glucose range: 140 to 180 mg/dL (majority of critically ill and noncritically ill patients; <140 mg/dL may be appropriate for selected patients, if it can be achieved without excessive hypoglycemia).
Perioperative care in adult patients (ADA 2021): Target glucose range during perioperative period: Consider targeting 80 to 180 mg/dL.
Children and adolescents:
Preprandial glucose: 70 to 130 mg/dL (ISPAD [Dimeglio 2018]).
Postprandial glucose: 90 to 180 mg/dL (ISPAD [Dimeglio 2018]).
Bedtime/overnight glucose: 80 to 140 mg/dL (ISPAD [Dimeglio 2018]).
HbA1c: <7%; target should be individualized; a more stringent goal (<6.5%) may be reasonable if it can be achieved without significant hypoglycemia; less aggressive goals (<7.5% or <8%) may be appropriate in patients who cannot articulate symptoms of hypoglycemia, cannot check glucose frequently, have a history of severe hypoglycemia, or have extensive comorbid conditions (ADA 2021; ISPAD [Dimeglio 2018]).
Surgical patients (ISPAD [Jefferies 2018]):
Intraoperative: 90 to 180 mg/dL.
ICU, postsurgery: 140 to 180 mg/dL.
Classification of hypoglycemia (ADA 2021):
Level 1: 54 to 70 mg/dL; hypoglycemia alert value; initiate fast-acting carbohydrate (eg, glucose) treatment.
Level 2: <54 mg/dL; threshold for neuroglycopenic symptoms; requires immediate action.
Level 3: Hypoglycemia associated with a severe event characterized by altered mental and/or physical status requiring assistance.
Insulin acts via specific membrane-bound receptors on target tissues to regulate metabolism of carbohydrate, protein, and fats. Target organs for insulin include the liver, skeletal muscle, and adipose tissue.
Within the liver, insulin stimulates hepatic glycogen synthesis. Insulin promotes hepatic synthesis of fatty acids, which are released into the circulation as lipoproteins. Skeletal muscle effects of insulin include increased protein synthesis and increased glycogen synthesis. Insulin stimulates lipoprotein lipase synthesis and activity; this results in hydrolysis of triglycerides into free fatty acids and storage of free fatty acids in adipocytes, thereby reducing circulating triglyceride levels (Rawla 2018; Sadur 1982; Song 2019). In addition, insulin stimulates the cellular uptake of amino acids and increases cellular permeability to several ions, including potassium, magnesium, and phosphate. By activating sodium-potassium ATPases, insulin promotes the intracellular movement of potassium.
Normally secreted by the pancreas, insulin products are manufactured for pharmacologic use through recombinant DNA technology using either E. coli or Saccharomyces cerevisiae. Insulin aspart differs from human insulin by containing aspartic acid at position B28 in comparison to the proline found in human insulin. Insulins are categorized based on the onset, peak, and duration of effect (eg, rapid-, short-, intermediate-, and long-acting insulin). Insulin aspart is a rapid-acting insulin analog.
Note: Onset and duration of hypoglycemic effects depend upon the route of administration, site of injection (onset and duration are progressively slower with SUBQ injection into the abdomen, arm, buttock, or thigh respectively), volume and concentration of injection, and the preparation administered. Rate of absorption, onset, and duration of activity may be affected by exercise, presence of lipodystrophy, local blood supply, and/or temperature. Insulin aspart is available in a conventional formulation (eg, NovoLOG, NovoRapid [Canadian product]) and a faster-acting formulation (Fiasp) which have slightly different pharmacodynamic/kinetic profiles.
Onset of action: SUBQ:
Fiasp: 16.1 minutes in patients with type 1 diabetes (~5 minutes earlier than conventional insulin aspart) (Heise 2017); 22.4 ± 1.5 minutes in patients with type 2 diabetes (~9 minutes earlier than conventional insulin aspart) (Pieber 2019).
NovoLOG: ~0.2 to 0.3 hours (estimated from data in manufacturer's labeling).
Peak effect:
Fiasp: ~1.5 to 2.2 hours in patients with type 1 diabetes (Heise 2017; manufacturer's labeling); peak occurred (~10 minutes earlier than conventional insulin aspart) (Heise 2017); ~2.5 ± 0.15 hours in patients with type 2 diabetes (~5 minutes earlier than conventional insulin aspart) (Pieber 2019).
NovoLOG: 1 to 3 hours in patients with type 1 diabetes (manufacturer's labeling).
Duration: SUBQ:
Fiasp: ~5 to 7 hours in patients with type 1 diabetes (dose dependent) (manufacturer's labeling); the offset of glucose lowering effect (time to decrease to 50% of maximum effect) occurred ~14 minutes earlier with Fiasp compared to conventional insulin aspart (Heise 2017; Pieber 2019).
NovoLOG: 3 to 7.2 hours in patients with type 1 diabetes (Kapitza 2020; manufacturer's labeling).
Protein binding: <10%.
Half-life elimination: SUBQ: Fiasp: 1.1 hours; NovoLOG: 81 minutes.
Time to peak, plasma: SUBQ:
Fiasp: ~63 minutes in patients with type 1 diabetes (Heise 2017; manufacturer's labeling); peak occurred ~7 minutes earlier than conventional insulin aspart (Heise 2017); 70 ± 5.4 minutes in patients with type 2 diabetes (~17 minutes earlier than conventional insulin aspart) (Pieber 2019).
NovoLOG: 40 to 50 minutes (manufacturer's labeling).
Obesity: NovoLOG clearance is reduced 28% in patients with a BMI >32 kg/m2 compared with patients with a BMI <23 kg/m2.
