SIDE EFFECTS

The following adverse reactions are discussed elsewhere:

• Hypoglycemia [see警告ANDPRECAUTIONS].
• Hypokalemia[see警告ANDPRECAUTIONS].

The following additional adverse reactions have been identified during post-approval use of HUMULIN R U-500. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to establish a causal relationship to drug exposure.

Hypoglycemia

低血糖症是最常见的不良reaction in patients using insulin, including HUMULIN R U-500 [see警告ANDPRECAUTIONS].

Allergic Reactions

Severe, life-threatening, generalizedallergy, includinganaphylaxis, generalized skin reactions, rash,angioedema, bronchospasm,hypotension, andshockmay occur with any insulin, including HUMULIN R U-500 and may be life threatening [see警告ANDPRECAUTIONS].

Lipodystrophy

Long-term use of insulin, including HUMULIN R U-500, can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening ofadiposetissue) and lipoatrophy (thinning of adipose tissue) and may affect insulin absorption. Rotate insulin injections sites within the same region to reduce the risk of lipodystrophy [seeDOSAGE AND ADMINISTRATION].

Injection Site Reactions

Patients taking HUMULIN R U-500 may experience injection site reactions, including injection sitehematoma, pain,hemorrhage,erythema, nodules, swelling, discoloration,公关uritus, warmth, and injection site mass.

Weight Gain

Weight gain can occur with insulin therapy, including HUMULIN R U-500, and has been attributed to the anabolic effects of insulin.

Peripheral Edema

Insulin, including HUMULIN R U-500, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.

Immunogenicity

As with all therapeutic proteins, insulin administration may cause anti-insulin antibodies to form. The presence of antibodies that affect clinical efficacy may necessitate dose adjustments to correct for tendencies toward hyper- or hypoglycemia.

The incidence of antibody formation with HUMULIN R U-500 is unknown.

DRUG INTERACTIONS

Drugs That May Increase The Risk Of Hypoglycemia

The risk of hypoglycemia associated with HUMULIN R U-500 use may be increased with antidiabetic agents,ACE inhibitors,angiotensinII receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, propoxyphene, salicylates,somatostatinanalogs (e.g., octreotide), and sulfonamide antibiotics. Dose adjustment and increased frequency of glucose monitoring may be required when HUMULIN R U-500 is co-administered with these drugs.

Drugs That May Decrease The Blood Glucose Lowering Effect Of HUMULIN R U-500

The glucose lowering effect of HUMULIN R U-500 may be decreased when co-administered withatypicalantipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics,estrogens, glucagon, isoniazid,niacin、口服避孕药、吩噻嗪类、孕激素s (e.g., in oral contraceptives),公关oteaseinhibitors,somatropin, sympathomimetic agents (e.g., albuterol,epinephrine, terbutaline) andthyroid hormones. Dose adjustment and increased frequency of glucose monitoring may be required when HUMULIN R U-500 is co-administered with these drugs.

Drugs That May Increase Or Decrease The Blood Glucose Lowering Effect Of HUMULIN R U-500

The glucose lowering effect of HUMULIN R U-500 may be increased or decreased when co-administered with alcohol, betablockers, clonidine, andlithiumsalts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Dose adjustment and increased frequency of glucose monitoring may be required when HUMULIN R U-500 is co-administered with these drugs.

Drugs That May Affect Signs And Symptoms Of Hypoglycemia

The signs and symptoms of hypoglycemia [see警告ANDPRECAUTIONS] may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are co-administered with HUMULIN R U-500.

PRECAUTIONS

Hyperglycemia, Hypoglycemia Or Death Due To Dosing Errors With The Vial Presentation

Medication errors associated with the HUMULIN R U-500 vial presentation resulting in patients experiencing hyperglycemia, hypoglycemia or death have been reported. The majority of errors occurred due to errors in dispensing, prescribing or administration. Attention to details at all levels may prevent these errors.

配药错误

Instruct patients to always inspect insulin vials to confirm that the correct insulin is dispensed including the correct insulin brand and concentration.

The HUMULIN R U-500 vial, which contains 20 mL, has a band of aqua coloring, a 500 units/mL concentration statement consisting of white lettering on a green rectangular background, and a green “U-500” statement prominently displayed next to the trade name. Additionally, the vial has a green flip top and a red warning on the front panel describing the highly concentrated dose and a statement advising use with only U-500 insulin syringes.

Prescribing Errors

Dosing errors have occurred when the HUMULIN R U-500 dose was administered with syringes other than a U-500 insulin syringe. Patients should be prescribed U-500 syringes for use with the HUMULIN R U-500 vials. The prescribed dose of HUMULIN R U-500 should always be expressed in units of insulin [seeDOSAGE AND ADMINISTRATION].

Administration Errors

Instruct patients to always check the insulin label before each injection.

只使用一个U - 500与HUMULIN R U -胰岛素注射器500 to avoid administration errors. Do not use any other type of syringe to administer Humulin R U-500. Adhere to administration instructions [seeDOSAGE AND ADMINISTRATION].

Instruct the patient to inform hospital or emergency department staff of the dose of HUMULIN R U-500 prescribed, in the event of a future hospitalization or visit to the急诊科.

Never Share A HUMULIN R U-500 KwikPen Or U-500 Insulin Syringe Between Patients

HUMULIN R U-500 KwikPens should never be shared between patients, even if the needle is changed. Patients using HUMULIN R U-500 vials should never share needles or U-500 insulin syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens.

Hyperglycemia Or Hypoglycemia With Changes In Insulin Regimen

Changes in insulin, manufacturer, type, or method of administration may affect glycemic control and公关edisposeto hypoglycemia or hyperglycemia. These changes should be made cautiously and only under medical supervision and the frequency of blood glucose monitoring should be increased. For patients withtype 2 diabetes, adjustments in concomitant oral anti-diabetic treatment may be needed.

Hypoglycemia

Hypoglycemia is the most common adverse reaction associated with insulin, including HUMULIN R U-500. Severe hypoglycemia can cause seizures, may be life-threatening or cause death. Severe hypoglycemia may develop as long as 18 to 24 hours after an injection of HUMULIN R U-500. 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) [seeDRUG INTERACTIONS], or in patients who experiencerecurrenthypoglycemia.

Risk Factors For Hypoglycemia

The timing of hypoglycemia usually reflects the time-action profile of the administered insulin formulation. As with all insulin preparations, the glucose lowering effect time course of HUMULIN R U-500 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. 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 [seeDRUG INTERACTIONS]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [seeUse 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 anessentialrole 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. To minimize the risk of hypoglycemia do not administer HUMULIN R U-500 intravenously, intramuscularly or in aninsulin pumpor dilute or mix HUMULIN R U-500 with any other insulin products or solutions [seeDOSAGE AND ADMINISTRATION].

Hypersensitivity And Allergic Reactions

Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including HUMULIN R U-500 [seeADVERSE REACTIONS]. If hypersensitivity reactions occur, discontinue HUMULIN R U-500; treat per标准治疗and monitor until symptoms and signs resolve [seeADVERSE REACTIONS].

Hypokalemia

All insulin products, including HUMULIN R U-500, cause a shift inpotassiumfrom theextracellularto intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratoryparalysis,ventriculararrhythmia, and death. Use caution in patients who may be at risk for hypokalemia (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 doserelated fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbateheart failure. Patients treated with insulin, including HUMULIN R U-500, and a PPAR-gammaagonistshould 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.

Patient Counseling Information

See FDA-approvedpatient labeling.

Patients should be counseled that HUMULIN R U-500 is a 5-times concentrated insulin product. Extreme caution must be observed in the measurement of dosage because inadvertent overdose may result in serious adverse reaction or life-threatening hypoglycemia. Accidental mix-ups between HUMULIN R U-500 and other insulins have been reported. To avoid medication errors between HUMULIN R U-500 and other insulins, patients should be instructed to always check the insulin label before each injection [see警告AND PRECAUTIONS].

If using the HUMULIN R U-500 KwikPen, patients should be counseled to dial and dose the prescribed number of units of insulin (no dose conversion is required) [seeDOSAGE AND ADMINISTRATION].

When using HUMULIN R U-500 from a vial, patients should be counseled to use only a U-500 insulin syringe and be informed that no dose conversion is required [seeDOSAGE AND ADMINISTRATION].

Patients should be instructed on self-management procedures including glucose monitoring, proper injection technique, and management of hypoglycemia and hyperglycemia, especially at initiation of HUMULIN R U-500 therapy. Patients must be instructed on handling of special situations such as intercurrent conditions (illness,stress, or emotional disturbances), an inadequate or skipped insulin dose, inadvertent administration of an increased insulin dose, inadequate food intake, and skipped meals. Refer patients to the HUMULIN R U-500 Patient Information Leaflet for additional information [see警告AND PRECAUTIONS].

Women with diabetes should be advised to inform their doctor if they are pregnant or are contemplating pregnancy.

Parenteraldrug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Never use HUMULIN R U-500 if it has become viscous (thickened) or cloudy; use it only if it is clear and colorless.

HUMULIN R U-500 should not be used after the printed expiration date.

Do not dilute or mix HUMULIN R U-500 with any other insulin products or solutions [seeDOSAGE AND ADMINISTRATION].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity and fertility studies were not performed with HUMULIN R U-500 in animals. Biosynthetic human insulin was not genotoxic in the in vivo sister chromatid exchange assay and the in vitro gradient plate and unscheduled DNA synthesis assays.

Use In Specific Populations

Pregnancy

Pregnancy Category B

Risk Summary

All pregnancies have a background risk of birth defects, loss, or other adverse outcome regardless of drug exposure. This background risk is increased in pregnancies complicated by hyperglycemia and may be decreased with good metabolic control. It is essential for patients with diabetes or history ofgestational diabetesto maintain good metabolic control beforeconceptionand throughout pregnancy. In patients with diabetes or gestational diabetes, insulin requirements may decrease during the first trimester, generally increase during the second and third trimesters, and rapidly decline after delivery. Careful monitoring of glucose control is essential in these patients. Therefore, female patients should be advised to tell their physicians if they intend to become, or if they become pregnant while taking HUMULIN R U-500.

Human Data

While there are no adequate and well-controlled studies in pregnant women, evidence from published literature suggests that good glycemic control in patients with diabetes during pregnancy provides significant maternal and fetal benefits.

Animal Data

Reproduction and fertility studies were not performed in animals.

Nursing Mothers

Endogenous insulin is present in human milk. Insulin orally ingested is degraded in thegastrointestinal tract. No adverse reactions associated with infant exposure to insulin through the consumption of human milk have been reported. In a study of eight preterm infants between 26 to 30 weeks gestation,enteraladministration of biosynthetic human insulin did not result in hypoglycemia. Good glucose control supports lactation in patients with diabetes. Women with diabetes who are lactating may require adjustments in their insulin dose.

Pediatric Use

There are no well-controlled studies of use of HUMULIN R U-500 in children. Standard precautions as applied to use of HUMULIN R U-500 in adults are appropriate for use in children. As in adults, the dosage of HUMULIN R U-500 in pediatric patients must be individualized based on metabolic needs and results of frequent monitoring of blood glucose.

Geriatric Use

The effect of age on the pharmacokinetics and pharmacodynamics of HUMULIN R U-500 has not been studied. Caution should be exercised when HUMULIN R U-500 is administered to geriatric patients. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemia.

Renal Impairment

Frequent glucose monitoring and insulin dose reduction may be required in patients with renal impairment.

Hepatic Impairment

Frequent glucose monitoring and insulin dose reduction may be required in patients with hepatic impairment.

OVERDOSE

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 withintramuscular/subcutaneous glucagon or concentrated intravenous glucose. Sustainedcarbohydrateintake and observation may be necessary because hypoglycemia may recur after apparent clinical recovery. Hypokalemia must be corrected appropriately.

CONTRAINDICATIONS

HUMULIN R U-500 is contraindicated:

• During episodes of hypoglycemia
• In patients who are hypersensitive to HUMULIN R U-500 or any of its excipients.

CLINICAL PHARMACOLOGY

Mechanism Of Action

Regulation of glucosemetabolismis the primary activity of insulins, including HUMULIN R U-500. Insulins lower blood glucose by stimulating peripheral glucose uptake byskeletal muscleand fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis, and enhance protein synthesis.

Pharmacodynamics

In a euglycemic clamp study of 24 healthyobesesubjects (BMI=30-39 kg/m²), single doses of HUMULIN R U-500 at 50 units (0.4-0.6 unit/kg) and 100 units (0.8-1.3 unit/kg) resulted in a mean time of onset of action of less than 15 minutes at both doses and a mean duration of action of 21 hours (range 13-24 hours). The time action characteristics reflect both公关andialand basal activity, consistent with clinical experience. This effect has been attributed to the high concentration of the preparation.

Figure 1 should be considered a representative example since the time course of action of insulin may vary in different individuals or within the same individual. The rate of insulin absorption and consequently the onset of activity is known to be affected by the site of injection, exercise, and other variables [see警告ANDPRECAUTIONS].

Figure 1: Mean Insulin Activity Versus Time Profiles After Subcutaneous Injection of a 100 U Dose of HUMULIN R U-500 in Healthy Obese Subjects

Pharmacokinetics

Absorption

In a euglycemic clamp study of 24 healthy obese subjects, the median peak insulin level occurred between 4 hours (50 unit dose) and 8 hours (100 unit dose) with a range of 0.5-8 hours.

Metabolism

The uptake and degradation of insulin occurs predominantly in liver, kidney, muscle, and adipocytes, with the liver being the major organ involved in the clearance of insulin.

Elimination

Mean apparent half-life after subcutaneous administration of single doses of 50 units and 100 units to healthy obese subjects (N≥21) was approximately 4.5 hours (range=1.9-10 hours) for HUMULIN R U-500.
