Admelog Prescribing Information
ADMELOG is indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus.
Important Preparation and Administration Instructions
- Always check insulin labels before administration [see Warnings and Precautions (5.4)].
- Inspect ADMELOG visually before use. It should appear clear and colorless. Do not use ADMELOG if particulate matter or coloration is seen.
- Use ADMELOG SoloStar prefilled pen with caution in patients with visual impairment who may rely on audible clicks to dial their dose.
- Do NOT mix ADMELOG with other insulins when administering using a continuous subcutaneous infusion pump.
Preparation and Administration Instructions for the Approved Routes of Administration
Subcutaneous Injection
- Administer the dose of ADMELOG subcutaneously within fifteen minutes before a meal or immediately after a meal into the abdominal wall, thigh, upper arm, or buttocks.
- Rotate 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), Adverse Reactions (6)].
- During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2)].
- ADMELOG administered by subcutaneous injection should generally be used in regimens with intermediate or long-acting insulin.
- The ADMELOG SoloStar prefilled pen dials in 1-unit increments.
- Prior to subcutaneous use, ADMELOG may be diluted with sterile 0.9% Sodium Chloride Injection. Dilute one-part ADMELOG to one-part 0.9% Sodium Chloride Injection to yield a concentration one-half that of ADMELOG (equivalent to U-50). If diluted ADMELOG is not used immediately, refrigerate at 2°C to 8°C (36°F to 46°F) for no more than 24 hours or store at room temperature up to 30°C (86°F) for 4 hours. Discard the unused diluted ADEMLOG after 24 hours if refrigerated or after 4 hours if stored at room temperature.
Continuous Subcutaneous Infusion (Insulin Pump)
- Refer to the continuous subcutaneous insulin infusion pump user manual to see if ADMELOG can be used with the insulin pump. Use ADMELOG in accordance with the insulin pump system's instructions for use.
- Administer ADMELOG by continuous subcutaneous infusion in a region recommended in the instructions from the pump manufacturer. Rotate infusion sites within the same region 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), Adverse Reactions (6)].
- Train patients using continuous subcutaneous insulin infusion therapy to administer insulin by injection and have alternate insulin therapy available in case of insulin pump failure [see Warnings and Precautions (5.8)].
- During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2)].
- Change ADMELOG in the pump reservoir at least every 7 days or according to the pump user manual, whichever is shorter.
- Change the infusion sets and the infusion set insertion site according to the manufacturer's user manual.
- Do NOT dilute or mix ADMELOG when administering by continuous subcutaneous infusion.
- Do NOT expose ADMELOG in the pump reservoir to temperatures greater than 98.6°F (37°C).
Intravenous Administration
- Administer ADMELOG intravenously ONLY under medical supervision [see Warnings and Precautions (5.3, 5.6)].
- Dilute ADMELOG to concentrations from 0.1 unit/mL to 1 unit/mL using 0.9% Sodium Chloride Injection, USP [see How Supplied/Storage and Handling (16.2)].
- Closely monitor of blood glucose and potassium levels to avoid hypoglycemia and hypokalemia [see Warnings and Precautions (5.3, 5.6)].
Dosage Recommendations
- Individualize and adjust the dosage of ADMELOG based on the route of administration, the patient's metabolic needs, blood glucose monitoring results, and glycemic control goal.
- Dosage modifications 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 lispro product to ADMELOG, the dose of ADMELOG should be the same as the other insulin lispro product [see Warnings and Precautions (5.2)].
- When switching from other insulins to ADMELOG, the ADMELOG dosage may need to be adjusted [see Warnings and Precautions (5.2)].
Dosage Adjustment for Drug Interactions
- Dosage modification may be needed when ADMELOG is coadministered with certain drugs [see Drug Interactions (7)].
- Do NOT mix ADMELOG with any other insulin.
Injection: 100 units/mL (U-100) is a clear and colorless solution available as:
- 10 mL multiple-dose vials
- 3 mL multiple-dose vials
- 3 mL single-patient-use SoloStar prefilled pens
Pregnancy
Risk Summary
Published studies with another insulin lispro product 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 another insulin lispro product in animal reproduction studies during organogenesis. Fetal growth retardation was observed in offspring of rats exposed to insulin lispro at a dose approximately 3 times the human subcutaneous dose of 1.0 unit/kg/day. No adverse effects on embryo-fetal development were observed in offspring of rabbits exposed to insulin lispro at doses up to approximately 0.24 times the human subcutaneous dose of 1.0 unit/kg/day [see Data].
The estimated background risk of major birth defects is 6%–10% in women with pregestational 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, preeclampsia, 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 another insulin lispro product 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 with another insulin lispro product, female rats were given subcutaneous insulin lispro injections of 5 and 20 units/kg/day (0.8 and 3 times the human subcutaneous dose of 1 unit/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 observed 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 with another insulin lispro product, insulin lispro doses of 0.1, 0.25, and 0.75 unit/kg/day (0.03, 0.08, and 0.24 times the human subcutaneous dose of 1 unit/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 suggest 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 ADMELOG and any potential adverse effects on the breastfed child from ADMELOG or from the underlying maternal condition.
Pediatric Use
The safety and effectiveness of ADMELOG to improve glycemic control have been established in pediatric patients with diabetes mellitus. Use of ADMELOG for this indication is supported by evidence from an adequate and well-controlled study with another insulin lispro product, 100 units/ml, in 60 pediatric patients 3 years of age and older with type 1 diabetes mellitus and studies in adult patients with diabetes mellitus [see Clinical Studies (14)].
Geriatric Use
Of the total number of patients (n=2,834) in eight clinical studies of another insulin lispro product, 100 units/mL, 12% (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.
Of the total number of patients (n=1,011) in clinical studies of ADMELOG or another insulin lispro product, 100 units/mL, 26.5% (n=268) 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 ADMELOG action have not been performed.
Renal Impairment
Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent ADMELOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology (12.3)].
Hepatic Impairment
Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent ADMELOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology (12.3)].
ADMELOG is contraindicated:
- during episodes of hypoglycemia [see Warnings and Precautions (5.3)].
- in patients who are hypersensitive to insulin lispro or to any of the excipients in ADMELOG [see Warnings and Precautions (5.5)].
Never Share an ADMELOG SoloStar Pen or Syringe Between Patients
ADMELOG SoloStar prefilled pen must never be shared between patients, even if the needle is changed. Patients using ADMELOG 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 (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 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.
Hypoglycemia
Hypoglycemia is the most common adverse reaction associated with insulins, including ADMELOG.
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 (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 ADMELOG 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 (12.2)]. 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 (7)]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6, 8.7)].
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 ADMELOG and other insulins, instruct patients to always check the insulin label before each injection.
Hypersensitivity Reactions
Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulins, including ADMELOG. If hypersensitivity reactions occur, discontinue ADMELOG; treat per standard of care and monitor until symptoms and signs resolve [see Adverse Reactions (6.1)]. ADMELOG is contraindicated in patients who have had hypersensitivity reactions to insulin lispro or any of the excipients in ADMELOG [see Contraindications (4)].
Hypokalemia
All insulins, including ADMELOG, 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 ADMELOG, 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 ADMELOG 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 (16.2) and Patient Counseling Information (17)].
