Consider Humalog for your patients with diabetes who:
- Need rapid-acting insulin, in addition to long-acting insulin, to manage postmeal glucose levels
- Need to add mealtime insulin injections to current basal insulin injections
- In your opinion are appropriate for this treatment plan
- Are ready to start mealtime insulin
- Want an insulin regimen that allows flexibility around family meals
Dosage of Humalog must be individualized. Humalog given by subcutaneous injection should generally be used in regimens with intermediate- or long-acting insulins.

Select Important Safety Information
Humalog and Insulin Lispro Injection are contraindicated during episodes of hypoglycemia and in patients who are hypersensitive to these insulins or any of their excipients.
In patients with Type 1 Diabetes:
Humalog U-100 reduced postprandial blood glucose compared to regular human insulin*1,2
In pediatric patients, Humalog reduced PPG to a greater extent than regular insulin; A1C did not differ between patients treated with regular insulin and those treated with Humalog.3,4
Study Design3
61 children (2.9 to 11.4 years), mean baseline A1C 8.4% ± 1.0%
- Diagnosed ≥12 months earlier
- Receiving human basal insulin (NPH, lente, or ultralente) plus human regular insulin (≥2 months prior to randomization)
3-way crossover study
-
3 treatment regimens
- Humalog immediately postmeal
- Humalog 15 minutes premeal
- Regular human insulin 30-45 minutes premeal
- Prestudy basal insulin regimen continued during study
- All patients received all 3 treatment regimens for 3 months per regimen in a crossover design
- Mean total daily insulin dose for all treatments was 0.8 U/kg/day
- No difference in A1C or rate of hypoglycemia among the 3 therapies
Insulin lispro administered 15 minutes compared with regular human insulin administered 30-45 minutes before meals lowered postprandial glucose after breakfast (11.7 mmol/L vs 15.0 mmol/L; p>.001) and the evening meal (8.8 mmol/L vs 10.8 mmol/L; p=.006).3 Insulin lispro administered before meals compared with regular human insulin administered 30-45 minutes before meals resulted in lower postprandial glucose after breakfast (9.7 mmol/L vs 10.6 mmol/L; p>.001) and the evening meal (8.6 mmol/L and 9.3 mmol/L, p=.003) in adolescents with type 1 diabetes.4
Select Safety Information
Humalog has not been studied in children with type 1 diabetes less than 3 years of age or in children with type 2 diabetes.
Never share a Humalog or Insulin Lispro Injection prefilled pen, cartridge, reusable pen compatible with Lilly 3 mL cartridges, or syringe between patients as it poses a risk for transmission of blood-borne pathogens.
In patients with Type 1 Diabetes:
Humalog U-100 provided improved glycemic control when used in an external insulin pump5
Humalog effectively improved A1C and blood glucose stability in patients with type 1 diabetes using insulin pumps.5,6,7 Humalog in an external insulin pump is approved for use in children with type 1 diabetes 4 years of age and older.
Adult Pump Use
In a 24-week, open-label, randomized, crossover multicenter study (N=39), using Humalog effectively improved A1C and blood glucose stability in patients using insulin pumps when compared to regular human insulin.6 The use of Humalog significantly reduced A1C and postprandial glucose levels, without increasing hypoglycemic episodes.6 See full study design and results below.
Administer Humalog U-100 by continuous subcutaneous infusion using an insulin pump. Do NOT mix Humalog U-100 with other insulins when administering using a continuous subcutaneous infusion pump.
Pediatric Pump Use
In a 16-week, open-label, parallel-group, multicenter study of children and adolescents with type 1 diabetes (N=298) aged 4 to 18 years, Humalog demonstrated comparable changes from baseline A1C and comparable rates of hypoglycemia as insulin aspart.7 See study design below.
Only the U-100 formulation of Humalog is approved for use in children age 3 or older by continuous subcutaneous infusion in insulin pumps.
Humalog has not been studied in pediatric patients younger than 3 years of age.
Humalog has not been studied in pediatric patients with type 2 diabetes.

Adult Pump Use Full Study Design and Results
A randomized, crossover, open-label study (N=39) compared insulin lispro (IL) with regular human insulin (U-100) in patients with type 1 diabetes mellitus (mean age 39). Both were administered in an insulin pump (MiniMed 506). Each treatment was given for 3 months and then switched to the other for 3 months. In the IL cohort, the A1C decreased from 7.74 ± 0.20% at baseline to 7.11 ± 0.15% at 12 weeks of period 1. The U-100 cohort showed a decrease in A1C from 7.97 ± 0.13 to 7.88 ± 0.16%; the difference between IL and U-100 was significant (p=.01). Mean daily and 2-hour postprandial blood glucose was also significantly lower in the IL than U-100 cohort (p<.0001). The rate of hypoglycemia determined in the last 30 days of the first treatment period was 7.03 versus 7.94 events/month with IL and U-100, respectively.6 In a second study, 113 subjects (mean age 37.1 years) with type 1 diabetes mellitus were treated with IL or U-100 administered by continuous subcutaneous insulin infusion. The study was a randomized, crossover design in which each treatment was administered for 4 months. The baseline A1C was 7.24% and decreased to 6.77 ± 0.88% and 6.90 ± 0.97% in the IL and U-100 cohorts, respectively (p<.02). The postprandial glucose was reduced after breakfast (run-in 8.5 to 7.0 and 8.6 mmol/L), lunch (8.4 to 7.6 and 8.7 mmol/L), and dinner (8.2 to 7.6 and 8.3 mmol/L) in IL and U-100 cohorts, respectively (all p<.001). The total number of hypoglycemia episodes per patient was not significantly different between treatments (12.4 versus 11.0 in the IL and U-100 cohorts, respectively).8
Pediatric Pump Use Study Design and Results
In a 16-week, parallel-group, open-label, multicenter study, children and adolescents with type 1 diabetes were randomly assigned to insulin aspart (n=198) or insulin lispro (n=100) administered by continuous subcutaneous insulin infusion.7 Approximately two-thirds of subjects in each treatment arm were aged 12-18 years. The A1C change from baseline to endpoint for insulin aspart and insulin lispro was 0.15% and 0.05%, respectively. Insulin aspart was noninferior to insulin lispro as the 95% CI for the difference in treatment did not exceed 0.4 (95% CI -0.27 to 0.07%). In general, the incidence and rate of hypoglycemia were similar between insulin aspart and insulin lispro. At least one major hypoglycemic event occurred in 9.6% of aspart and 8.0% of lispro subjects.
Important information about using Humalog U-100 in an insulin pump
Humalog should not be diluted or mixed with any other insulin when used in an external insulin pump. Change reservoir at least every 7 days. Change the infusion set and insertion site at least every 3 days.
Adverse reactions associated with Humalog in patients receiving continuous subcutaneous insulin infusion: in adult patients, catheter occlusions (0.09/month), infusion-site reactions (2.6%). In children and adolescents, infusion-site reactions (21%).
Select Important Safety Information
Malfunction of the insulin pump device, infusion set, or insulin degradation can rapidly lead to hyperglycemia and ketoacidosis. Patients using subcutaneous insulin infusion pumps must be trained to administer insulin by injection and have alternate insulin therapy available in case of pump failure.
In Adult Patients with Type 2 Diabetes:
Humalog dosed 15 minutes before or immediately after meals when added to a basal insulin:
- Reduced postprandial glucose levels1,2
- Lowered A1C
Compared to regular human insulin, Humalog U-100 lowered 2-hour postprandial glucose excursions
*In a study of 722 patients with type 2 diabetes, the increase in serum glucose levels at 2 hours following the test meal was 53% lower for Humalog relative to regular human insulin (p<.001). Actual values for the rise in glucose were 25.4 ± 1.8 mg/dL for Humalog vs 54.0 ± 1.8 mg/dL for regular human insulin.2
Select Important Safety Information
Changes in insulin regimen (e.g. insulin strength, manufacturer, type, injection site, or method of administration) may affect glycemic control and predispose patients to hypoglycemia and hyperglycemia. Make changes cautiously with increased frequency of blood glucose monitoring.
