- Do NOT mix HUMALOG U-100 with other insulins when using a continuous subcutaneous infusion pump.
- Do NOT transfer HUMALOG U-200 from the prefilled pen to a syringe for administration [see Warnings and Precautions ].
- Do NOT perform dose conversion when using any HUMALOG U-100 or U-200 prefilled pens. The dose window shows the number of insulin units to be delivered and no conversion is needed.
Administration Instructions for the Approved Routes of Administration
Subcutaneous Injection: HUMALOG U-100 or U-200
- Administer the dose of HUMALOG U-100 or HUMALOG U-200 within fifteen minutes before a meal or immediately after a meal by injection into the subcutaneous tissue of the abdominal wall, thigh, upper arm, or buttocks.
- Rotate the injection site within the same region from one injection to the next (abdominal wall, thigh, upper arm, or buttocks) to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions and Adverse Reactions ].
- During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions ].
- HUMALOG administered by subcutaneous injection should generally be used in regimens with an intermediate- or long-acting insulin.
- The HUMALOG U-100 KwikPen, HUMALOG U-100 Tempo Pen and HUMALOG U-200 KwikPen each dial in 1 unit increments and delivers a maximum dose of 60 units per injection.
- The HUMALOG U-100 Junior KwikPen dials in 0.5 unit increments and delivers a maximum dose of 30 units per injection.
Subcutaneous Injection: Diluted HUMALOG U-100
- HUMALOG U-100 may be diluted with Sterile Diluent for HUMALOG for subcutaneous injection ONLY under medical supervision. Dilute one part HUMALOG U-100 to:
- Nine parts diluent to yield a concentration one-tenth that of HUMALOG U-100 (equivalent to U-10).
- One part diluent to yield a concentration one-half that of HUMALOG U-100 (equivalent to U-50).

Pregnancy
Risk Summary
Published studies with insulin lispro used during pregnancy have not reported an association between insulin lispro and the induction of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations).
Pregnant rats and rabbits were exposed to insulin lispro in animal reproduction studies during organogenesis. No adverse effects on embryo/fetal viability or morphology were observed in offspring of rats exposed to insulin lispro at a dose approximately 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day. No adverse effects on embryo/fetal development were observed in offspring of rabbits exposed to insulin lispro at doses up to approximately 0.2 times the human subcutaneous dose of 1 unit/kg/day (see Data).
The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with a HbA1c >7 and has been reported to be as high as 20-25% in women with a HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Clinical Considerations
Disease-associated maternal and/or embryo/fetal risk
Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity.
Data
Human Data
Published data from retrospective studies and meta-analyses do not report an association with insulin lispro and major birth defects, miscarriage, or adverse maternal or fetal outcomes when insulin lispro is used during pregnancy. However, these studies cannot definitely establish or exclude the absence of any risk because of methodological limitations including small sample size, selection bias, confounding by unmeasured factors, and some lacking comparator groups.
Animal Data
In a combined fertility and embryo-fetal development study, female rats were given subcutaneous insulin lispro injections of 1, 5, and 20 units/kg/day (0.2, 0.8, and 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area, respectively) from 2 weeks prior to cohabitation through Gestation Day 19. There were no adverse effects on female fertility, implantation, or fetal viability and morphology. However, fetal growth retardation was produced at the 20 units/kg/day-dose as indicated by decreased fetal weight and an increased incidence of fetal runts/litter.
In an embryo-fetal development study in pregnant rabbits, insulin lispro doses of 0.1, 0.25, and 0.75 unit/kg/day (0.03, 0.08, and 0.2 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area, respectively) were injected subcutaneously on Gestation days 7 through 19. There were no adverse effects on fetal viability, weight, and morphology at any dose.
Lactation
Risk Summary
Available data from published literature suggests that exogenous human insulin products, including insulin lispro, are transferred into human milk. There are no adverse reactions reported in breastfed infants in the literature. There are no data on the effects of exogenous human insulin products, including insulin lispro, on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for insulin, any potential adverse effects on the breastfed child from HUMALOG or from the underlying maternal condition.
Pediatric Use
The safety and effectiveness of HUMALOG to improve glycemic control have been established in pediatric patients with diabetes mellitus. Use of HUMALOG for this indication is supported by evidence from adequate and well-controlled studies in 831 pediatric patients with type 1 diabetes mellitus aged 3 years and older and from studies in adults with diabetes mellitus [see Adverse Reactions , Clinical Pharmacology , and Clinical Studies ].
Geriatric Use
Of the total number of patients (n=2,834) in eight clinical studies of HUMALOG, twelve percent (n=338) were 65 years of age or over. The majority of these patients had type 2 diabetes. HbA1c values and hypoglycemia rates did not differ by age. Pharmacokinetic/pharmacodynamic studies to assess the effect of age on the onset of HUMALOG action have not been performed.
Renal Impairment
Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent HUMALOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology ].
Hepatic Impairment
Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent HUMALOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology ].
HUMALOG is contraindicated:
- during episodes of hypoglycemia [see Warnings and Precautions ].
- in patients who are hypersensitive to insulin lispro or to any of the excipients in HUMALOG [see Warnings and Precautions ].
Never Share a HUMALOG Prefilled Pen, Cartridge, Reusable Pen Compatible with Lilly 3 mL Cartridges1, or Syringe Between Patients
HUMALOG prefilled pens, cartridges, and reusable pens compatible with Lilly 3 mL cartridges must never be shared between patients, even if the needle is changed. Patients using HUMALOG vials must never share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens.
Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen
Changes in an insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) may affect glycemic control and predispose to hypoglycemia [see Warnings and Precautions ] or hyperglycemia. Repeated insulin injections into areas of lipodystrophy or localized cutaneous amyloidosis have been reported to result in hyperglycemia; and a sudden change in the injection site (to an unaffected area) has been reported to result in hypoglycemia [see Adverse Reactions ].
Make any changes to a patient's insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. Advise patients who have repeatedly injected into areas of lipodystrophy or localized cutaneous amyloidosis to change the injection site to unaffected areas and closely monitor for hypoglycemia. For patients with type 2 diabetes, dosage adjustments of concomitant antidiabetic products may be needed.
Hypoglycemia
Hypoglycemia is the most common adverse reaction associated with insulins, including HUMALOG. Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery).
Hypoglycemia can happen suddenly, and symptoms may differ in each individual and change over time in the same individual. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using medications that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions ], or in patients who experience recurrent hypoglycemia.
Risk Factors for Hypoglycemia
The risk of hypoglycemia after an injection is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulins, the glucose lowering effect time course of HUMALOG may vary in different individuals or at different times in the same individual and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature [see Clinical Pharmacology ]. Other factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to co-administered medication [see Drug Interactions ]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations ].
Risk Mitigation Strategies for Hypoglycemia
Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended.
Hypoglycemia Due to Medication Errors
Accidental mix-ups between insulin products have been reported. To avoid medication errors between HUMALOG and other insulins, instruct patients to always check the insulin label before each injection.
Do not transfer HUMALOG U-200 from the HUMALOG KwikPen to a syringe. The markings on the insulin syringe will not measure the dose correctly and can result in overdosage and severe hypoglycemia [see Dosage and Administration and Warnings and Precautions ].
Hypersensitivity Reactions
Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulins, including HUMALOG. If hypersensitivity reactions occur, discontinue HUMALOG; treat per standard of care and monitor until symptoms and signs resolve [see Adverse Reactions ]. HUMALOG is contraindicated in patients who have had hypersensitivity reactions to insulin lispro or any of the excipients in HUMALOG [see Contraindications ].
Hypokalemia
All insulins, including HUMALOG, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia if indicated (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).
Fluid Retention and Heart Failure with Concomitant Use of PPAR-gamma Agonists
Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including HUMALOG, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered.
Hyperglycemia and Ketoacidosis Due to Insulin Pump Device Malfunction
Malfunction of the insulin pump or insulin infusion set or insulin degradation can rapidly lead to hyperglycemia and ketoacidosis. Prompt identification and correction of the cause of hyperglycemia or ketosis is necessary. Interim subcutaneous injections with HUMALOG may be required. Patients using continuous subcutaneous insulin infusion pump therapy must be trained to administer insulin by injection and have alternate insulin therapy available in case of pump failure [see How Supplied/Storage and Handling and Patient Counseling Information ].
