📖 What it is MedlinePlus · NLM

Insulin lispro injection products are used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Insulin lispro injection products are also used to treat people with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) who need insulin to control their diabetes. In patients with type 1 diabetes, insulin lispro injection products are always used with another type of insulin, unless it is used in an external insulin pump. In...

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⏱️ Dosage and Administration ~2 min read ▾

2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for important preparation and administration instructions. ( 2.1 ) Inject HUMALOG Mix50/50 subcutaneously (within 15 minutes before a meal) in abdominal wall, thigh, upper arm, or buttocks and rotate injection sites to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.1 , 2.2 ) Individualize and adjust dosage based on metabolic needs, blood glucose monitoring results and glycemic control goal.

( 2.2 ) Do not administer HUMALOG Mix50/50 intravenously or by a continuous subcutaneous insulin infusion pump. ( 2.1 ) HUMALOG Mix50/50 is typically dosed twice daily (with each dose intended to cover 2 meals or a meal and a snack). ( 2.2 )

2.1Important Preparation and Administration Instructions Preparation Instructions Always check insulin labels before administration [see Warnings and Precautions ( 5.4 )] . HUMALOG Mix50/50 is a suspension that must be resuspended immediately before use. Resuspension is easier when the insulin has reached room temperature.

To resuspend the KwikPen, gently roll the KwikPen at least 10 times and then carefully invert the KwikPen at least 10 times until the suspension appears uniformly white and cloudy. Inspect HUMALOG Mix50/50 visually before use. Do not use if discoloration or particulate matter is seen.

Administration Instructions After resuspension, immediately administer HUMALOG Mix50/50 by subcutaneous injection into the abdominal wall, thigh, upper arm, or buttocks. Rotate the injection site within the same region from one injection to the next 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 ( 5.2 ) and Adverse Reactions ( 6 )] .

The HUMALOG Mix50/50 KwikPen dials in 1 unit increments. Use HUMALOG Mix50/50 KwikPen with caution in patients with visual impairment that may rely on audible clicks to dial their dose. Do not administer HUMALOG Mix50/50 intravenously or by a continuous subcutaneous insulin infusion pump.

Do not mix HUMALOG Mix50/50 with any other insulins or diluents.

2.2Dosage Recommendations Individualize and adjust the dosage of HUMALOG Mix50/50 based on the individual's metabolic needs, blood glucose monitoring results and glycemic control goal. Inject HUMALOG Mix50/50 subcutaneously within 15 minutes before a meal. HUMALOG Mix50/50 is typically dosed twice-daily (with each dose intended to cover 2 meals or a meal and a snack).

Dosage adjustments may be needed with changes in physical activity, changes in meal patterns (i.e., macronutrient content or timing of food intake), changes in renal or hepatic function or during acute illness [see Warnings and Precautions ( 5.2 , 5.3 ) and Use in Specific Populations ( 8.6 , 8.7 )] . When switching from another insulin to HUMALOG Mix50/50, a different dosage of HUMALOG Mix50/50 may be needed. During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions ( 5.2 )] .

2.3Dosage Modifications for Drug Interactions Dosage modification may be needed when HUMALOG Mix50/50 is used concomitantly with certain drugs [see Drug Interactions ( 7 )] .

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Never share a HUMALOG Mix50/50 KwikPen between patients, even if the needle is changed. ( 5.1 ) Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen: Make changes to a patient's insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) under close medical supervision with increased frequency of blood glucose monitoring. ( 5.2 ) Hypoglycemia: May be life-threatening.

Increase frequency of blood glucose monitoring with changes to insulin dosage, co-administered glucose lowering medications, meal pattern, physical activity; in patients with renal or hepatic impairment; and in patients with hypoglycemia unawareness. ( 5.3 ) Hypoglycemia Due to Medication Errors: Accidental mix-ups between insulin products can occur. Instruct patients to check insulin labels before injection.

( 5.4 ) Hypersensitivity Reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, can occur. Discontinue HUMALOG Mix50/50, monitor and treat if indicated. ( 5.5 ) Hypokalemia: May be life-threatening.

Monitor potassium levels in patients at risk of hypokalemia and treat if indicated. ( 5.6 ) Fluid Retention and Heart Failure with Concomitant Use of Thiazolidinediones (TZDs) : Observe for signs and symptoms of heart failure; consider dosage reductions or discontinuation if heart failure occurs. ( 5.7 )

5.1Never Share a HUMALOG Mix50/50 KwikPen Between Patients HUMALOG Mix50/50 KwikPens must never be shared between patients, even if the needle is changed. Sharing poses a risk for transmission of blood-borne pathogens.

5.2Hyperglycemia 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 ( 5.3 )] 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 ( 6 )] .

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 anti-diabetic products may be needed.

5.3Hypoglycemia Hypoglycemia is the most common adverse reaction associated with all insulins, including HUMALOG Mix50/50. Severe hypoglycemia can cause seizures, may lead to unconsciousness, 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 ( 7 )], 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 Mix50/50 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… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions ~2 min read ▾

6 ADVERSE REACTIONS The following adverse reactions are discussed elsewhere in the labeling: Hypoglycemia [see Warnings and Precautions ( 5.3 )] Hypoglycemia Due to Medication Errors [see Warnings and Precautions ( 5.4 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.5 )] Hypokalemia [see Warnings and Precautions ( 5.6 )] Adverse reactions observed with HUMALOG Mix50/50 include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, weight gain, edema, pruritus, and rash. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Adverse Reactions from Clinical Studies or Postmarketing Reports The following adverse reactions have been identified during post-marketing use of HUMALOG Mix50/50. Because some of these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Adverse reactions associated with insulin initiation and glucose control intensification Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy.

Over the long-term, improved glycemic control decreases the risk of diabetic retinopathy and neuropathy. Hypersensitivity reactions Severe, life-threatening, generalized allergy, including anaphylaxis. Hypoglycemia Hypoglycemia is the most commonly observed adverse reaction in HUMALOG Mix50/50.

Hypokalemia HUMALOG Mix50/50 can cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Injection site reactions HUMALOG Mix50/50 can cause local injection site reactions including redness, swelling, or itching at the site of injection. These reactions usually resolve in a few days to a few weeks, but in some occasions, may require discontinuation.

Localized reactions and generalized myalgias have been reported with the use of meta-cresol, which is an excipient in HUMALOG Mix50/50. Lipodystrophy Administration of insulin subcutaneously, including HUMALOG Mix50/50, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) [see Dosage and Administration ( 2.1 )] in some patients. Localized cutaneous amyloidosis Localized cutaneous amyloidosis at the injection site has occurred.

Hyperglycemia has been reported with repeated insulin injections into areas of localized cutaneous amyloidosis; hypoglycemia has been reported with a sudden change to an unaffected injection site. Medication Errors Medication errors in which other insulins have been accidentally substituted for HUMALOG Mix50/50 have been identified during postapproval use. Peripheral Edema Insulins, including HUMALOG Mix50/50, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.

Weight gain Weight gain can occur with insulins, including HUMALOG Mix50/50, and has been attributed to the anabolic effects of insulin and the decrease in glycosuria. Immunogenicity As with all therapeutic proteins, insulin administration may cause anti-insulin antibodies to form. The incidence of antibody formation with HUMALOG Mix50/50 is unknown.

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy 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, still birth, 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 Animal reproduction studies have not been performed with HUMALOG Mix50/50. However, subcutaneous reproduction and teratology studies have been conducted with insulin lispro (a component of HUMALOG Mix50/50). 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.

8.2Lactation 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 effec… [Excerpted — this section continues on DailyMed.]

🧓 Geriatric Use 57 words ▾

8.5Geriatric Use Clinical studies of Humalog Mix50/50 did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger patients. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.3 )].

🆘 Overdosage 85 words ▾

10 OVERDOSAGE Excess insulin administration may cause hypoglycemia and hypokalemia. Mild episodes of hypoglycemia usually can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise may be needed.

More severe episodes with coma, seizure, or neurologic impairment may be treated with a glucagon product for emergency use or concentrated intravenous glucose. Sustained carbohydrate intake and observation may be necessary because hypoglycemia may recur after apparent clinical recovery. Hypokalemia must be corrected appropriately [see Warnings and Precautions ( 5.3 , 5.6 )].

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The primary activity of insulin including HUMALOG Mix50/50 is the regulation of glucose metabolism. Insulins lower blood glucose by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis, and enhance protein synthesis.

12.2Pharmacodynamics In a glucose clamp study performed in 30 healthy subjects, the onset of action and glucose-lowering activity of HUMALOG, HUMALOG Mix50/50, HUMALOG ® Mix75/25™, and insulin lispro protamine suspension (ILPS) were compared ( see Figure 1). Graphs of mean glucose infusion rate versus time showed a distinct insulin activity profile for each formulation. The rapid onset of glucose-lowering activity characteristic of HUMALOG was maintained in HUMALOG Mix50/50.

The median maximum pharmacologic effect of HUMALOG Mix50/50 after administration of a 0.3 unit/kg dose to healthy subjects occurred at 2 hours (range: 1-5 hours); glucose lowering activity was detectable for a median of 22 hours (range: 11 to 22 hours), which was the end of the clamp. Figure 1 should be considered only as a representative example since the time course of action of insulin and insulin analogs, may vary in different individuals or within the same individual. Figure 1: Mean Insulin Activity Versus Time Profiles After Injection of 0.3 units/kg of HUMALOG, HUMALOG Mix50/50, HUMALOG Mix75/25, or Insulin Lispro Protamine Suspension (ILPS) in 30 Healthy Subjects.

Figure 1

12.3Pharmacokinetics Absorption — HUMALOG Mix50/50 has two phases of absorption. The early phase represents insulin lispro and its distinct characteristics of rapid onset. The late phase represents the prolonged absorption of insulin lispro protamine suspension.

In 30 healthy subjects given subcutaneous doses (0.3 unit/kg) of HUMALOG Mix50/50, the median peak serum concentration occurred at 60 minutes (range: 45 minutes to 13.5 hours) after dosing. In patients with type 1 diabetes, the median peak serum concentration occurred at 60 minutes (range: 45 minutes to 2 hours) after dosing. Metabolism — Human metabolism studies of HUMALOG Mix50/50 have not been conducted.

However, studies in animals indicate that the metabolism of HUMALOG, the rapid-acting component of HUMALOG Mix50/50, is identical to that of regular human insulin. Elimination — Because of the absorption-rate limited kinetics of insulin mixtures, a true half-life cannot be accurately estimated from the terminal slope of the concentration versus time curve. Specific Populations The effects of age, race, obesity, pregnancy, smoking, or renal or hepatic impairment on the pharmacokinetics of HUMALOG Mix50/50 have not been studied.

Gender — Pharmacokinetic and pharmacodynamic comparisons between men and women administered HUMALOG Mix50/50 showed no gender differences.

📋 Description ~1 min read ▾

11 DESCRIPTION Insulin lispro is a rapid-acting insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli . Insulin lispro differs from human insulin in that the amino acid proline at position B28 is replaced by lysine and the lysine in position B29 is replaced by proline. Chemically, it is Lys(B28), Pro(B29) human insulin analog and has the empirical formula C 257 H 383 N 65 O 77 S 6 and a molecular weight of 5.808 kDa, both identical to that of human insulin.

Humalog Mix50/50 (insulin lispro protamine and insulin lispro) injectable suspension is a mixture of 50% insulin lispro protamine, an intermediate-acting human insulin analog, and 50% insulin lispro, a rapid-acting human insulin analog. Insulin lispro protamine suspension is a suspension of crystals produced from combining insulin lispro and protamine sulfate under appropriate conditions for crystal formation. Insulin lispro has the following primary structure: HUMALOG Mix50/50 (insulin lispro protamine and insulin lispro) injectable suspension is a sterile, white and cloudy suspension for subcutaneous use.

Each mL of HUMALOG Mix50/50 contains 100 units of insulin lispro; dibasic sodium phosphate (2.0 mg), glycerin (16 mg), metacresol (2.20 mg), phenol (0.89 mg), protamine sulfate (0.19 mg), zinc oxide content adjusted to provide zinc ion (0.0305 mg), and Water for Injection, USP. The pH is 7.0 to 7.8. Sodium hydroxide and/or hydrochloric acid is added during manufacture to adjust the pH.

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Standard 2-year carcinogenicity studies in animals have not been performed with HUMALOG Mix50/50. In Fischer 344 rats, a 12-month repeat-dose toxicity study was conducted with insulin lispro (a component of HUMALOG Mix50/50) at subcutaneous doses of 20 and 200 units/kg/day (approximately 3 and 32 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area). Insulin lispro did not produce important target organ toxicity including mammary tumors at any dose.

Insulin lispro was not mutagenic in the following genetic toxicity assays: bacterial mutation, unscheduled DNA synthesis, mouse lymphoma, chromosomal aberration and micronucleus assays. Male fertility was not compromised when male rats given subcutaneous insulin lispro injections of 5 and 20 units/kg/day (0.8 and 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area) for 6 months were mated with untreated female rats. In a combined fertility, perinatal, and postnatal study in male and female rats given 1, 5, and 20 units/kg/day subcutaneously (0.2, 0.8, and 3 times the human subcutaneous dose of 1 unit insulin lispro/kg/day, based on units/body surface area), mating and fertility were not adversely affected in either gender at any dose.

Change (rotate) your injection sites within the area you choose for each dose to reduce your risk of getting lipodystrophy (pits in skin or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the injection sites. Do not inject where the skin has pits, is thickened, or has lumps. Do not inject where the skin is tender, bruised, scaly or hard, or into scars or damaged skin.

Step 11: Choose your injection site. HUMALOG Mix50/50 is injected under the skin (subcutaneously) of your stomach area (abdomen), buttocks, upper legs or upper arms. Wipe the skin with an alcohol swab.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q1 2026 · 5 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

💵 About the dollar figures: “reimbursed” is what Medicaid paid pharmacies before confidential manufacturer rebates, so the program’s real net cost is lower than these numbers. Fee-for-service and managed-care claims are combined unless split above. Source: CMS State Drug Utilization Data; per-100k rates use 2023 Census population estimates.

Medicaid utilization by pack size

Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Humalog Mix 50-50 Kwikpen — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Humalog Mix 50-50 Kwikpen. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.
