FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

HUMULIN N is indicated to improve glycemic control in adults and pediatric patients with diabetes mellitus.

2 DOSAGE AND ADMINISTRATION

2.1 Important Administration Instructions

Inspect HUMULIN N visually before use. It should not contain particulate matter and should appear uniformly cloudy after mixing. Do not use HUMULIN N if particulate matter is seen.

Use HUMULIN N KwikPen with caution in patients with visual impairment that may rely on audible clicks to dial their dose.

2.2 Route of Administration

HUMULIN N should only be administered subcutaneously.

Administer in the subcutaneous tissue of the abdominal wall, thigh, upper arm, or buttocks. Rotate injection sites 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)]. During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2)].

The HUMULIN N KwikPen dials in 1 unit increments.

Do not administer HUMULIN N intravenously and do not use HUMULIN N in an insulin infusion pump.

2.3 Dosage Information

Individualize and adjust the dosage of HUMULIN N based on the individual's metabolic needs, blood glucose monitoring results and glycemic control goal.

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)].

2.4 Dosage Adjustment due to Drug Interactions

Dosage adjustment may be needed when HUMULIN N is coadministered with certain drugs [see Drug Interactions (7)].

Dosage adjustment may be needed when changing from another insulin to HUMULIN N [see Warnings and Precautions (5.2)].

Instructions for Mixing with Other Insulins

HUMULIN N may be used with a prandial insulin if indicated. HUMULIN N may be mixed with HUMULIN R or HUMALOG before injection.

  • If HUMULIN N is mixed with HUMULIN R, HUMULIN R should be drawn into the syringe first. Injection should occur immediately after mixing.
  • If HUMULIN N is mixed with HUMALOG, HUMALOG should be drawn into the syringe first. Injection should occur immediately after mixing.

3 DOSAGE FORMS AND STRENGTHS

Injectable suspension: 100 units/mL (U-100) white and cloudy suspension available as:

4 CONTRAINDICATIONS

HUMULIN N is contraindicated:

5 WARNINGS AND PRECAUTIONS

5.1 Never Share a HUMULIN N KwikPen or Syringe Between Patients

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

5.2 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 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 antidiabetic products may be needed.

5.3 Hypoglycemia

Hypoglycemia is the most common adverse reaction associated with insulins, including HUMULIN N. Severe hypoglycemia can cause seizures, may be life-threatening or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place the patient 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 patient and change over time in the same patient. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic neuropathy, 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 HUMULIN N 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 concomitant drugs [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.

5.4 Hypoglycemia Due to Medication Errors

Accidental mix-ups between insulin products have been reported. To avoid medication errors between HUMULIN N and other insulins, instruct patients to always check the insulin label before each injection.

5.5 Hypersensitivity Reactions

Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulins, including HUMULIN N. If hypersensitivity reactions occur, discontinue HUMULIN N; treat per standard of care and monitor until symptoms and signs resolve [see Adverse Reactions (6)]. HUMULIN N is contraindicated in patients who have had hypersensitivity reactions to HUMULIN N or any of its excipients.

5.6 Hypokalemia

All insulins, including HUMULIN N, 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).

5.7 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, when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including HUMULIN N, 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.

6 ADVERSE REACTIONS

The following adverse reactions are discussed elsewhere in the labeling:

The following additional adverse reactions have been identified during post-approval use of HUMULIN N. 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.

Allergic Reactions

Some patients taking HUMULIN N have experienced erythema, local edema, and pruritus at the site of injection. These conditions were usually self-limiting. Severe cases of generalized allergy (anaphylaxis) have been reported [see Warnings and Precautions (5.5)].

Peripheral Edema

Some patients taking HUMULIN N have experienced sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.

Lipodystrophy

Administration of insulin subcutaneously, including HUMULIN N, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) [see Dosage and Administration (2.2)] 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.

Weight gain

Weight gain has occurred with insulins, including HUMULIN N, and has been attributed to the anabolic effects of insulin and the decrease in glycosuria.

Immunogenicity

Development of antibodies that react with human insulin have been observed with all insulins, including HUMULIN N.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

Available data from published studies over decades have not established an association with human insulin use during pregnancy and 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). Animal reproduction studies were not performed.

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

While available studies cannot definitively establish the absence of risk, published data from retrospective studies, open-label, randomized, parallel studies and meta-analyses over decades have not established an association with human insulin use during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes. All available studies have methodological limitations, including lack of blinding, unclear methods or randomization, and small sample size.

8.2 Lactation

Risk Summary

Available data from published literature suggests that exogenous human insulin products, including HUMULIN N, 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 HUMULIN N on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for HUMULIN N and any potential adverse effects on the breastfed child from HUMULIN N or from the underlying maternal condition.

8.4 Pediatric Use

HUMULIN N is indicated to improve glycemic control in pediatric patients with diabetes mellitus.

8.5 Geriatric Use

The effect of age on the pharmacokinetics and pharmacodynamics of HUMULIN N has not been studied [see Clinical Pharmacology (12.3)]. Patients with advanced age using any insulin, including HUMULIN N, may be at increased risk of hypoglycemia due to co-morbid disease and polypharmacy [see Warnings and Precautions (5.3)].

8.6 Renal Impairment

The effect of renal impairment on the pharmacokinetics and pharmacodynamics of HUMULIN N has not been studied [see Clinical Pharmacology (12.3)]. Patients with renal impairment are at increased risk of hypoglycemia and may require more frequent HUMULIN N dose adjustment and more frequent blood glucose monitoring.

8.7 Hepatic Impairment

The effect of hepatic impairment on the pharmacokinetics and pharmacodynamics of HUMULIN N has not been studied [see Clinical Pharmacology (12.3)]. Patients with hepatic impairment are at increased risk of hypoglycemia and may require more frequent HUMULIN N dose adjustment and more frequent blood glucose monitoring.

10 OVERDOSAGE

Excess insulin administration may cause hypoglycemia and hypokalemia [see Warnings and Precautions (5.3, 5.6)]. Mild episodes of hypoglycemia can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or physical activity level 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.

11 DESCRIPTION

Insulin isophane human is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli. Insulin isophane human is a suspension of crystals produced from combining human insulin and protamine sulfate under appropriate conditions for crystal formation. The amino acid sequence of insulin isophane human is identical to human insulin and has the empirical formula C257H383N65O77S6 with a molecular weight of 5.808 kDa.

HUMULIN N (insulin isophane human) injectable suspension is an intermediate acting human insulin. It is a sterile, white and cloudy suspension that contains insulin isophane human suspension (NPH) for subcutaneous use. Each milliliter of HUMULIN N contains 100 units of insulin human, dibasic sodium phosphate (3.78 mg), glycerin (16 mg), metacresol (1.6 mg), phenol (0.65 mg), protamine sulfate (0.35 mg), zinc oxide content adjusted to provide zinc ion (approximately 0.025 mg for the vials or approximately 0.035 mg for the KwikPen), and Water for Injection. The pH is 7.0 to 7.5. Sodium hydroxide and/or hydrochloric acid may be added during manufacture to adjust the pH.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

HUMULIN N lowers 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.

12.2 Pharmacodynamics

HUMULIN N is an intermediate-acting insulin with a slower onset of action and a longer duration of activity than that of regular human insulin. In a study in which healthy subjects (n=16) received subcutaneous injections of HUMULIN N (0.4 unit/kg) on 4 occasions, the median maximum effect occurred at 6.5 hours (range: 2.8 to 13 hours). In this study, insulin activity was measured by the rate of glucose infusions.

The time course of action of insulin, such as HUMULIN N may vary in different individuals or within the same individual. The parameters of HUMULIN N activity (time of onset, peak time, and duration) as designated in Figure 1 should be considered only as general guidelines. The rate of insulin absorption and consequently the onset of activity is known to be affected by the site of injection, physical activity level, and other variables [see Warnings and Precautions (5.3)].

Figure 1

Figure 1: Mean Insulin Activity Versus Time Profile After Subcutaneous Injection of HUMULIN N (0.4 unit/kg) in Healthy Subjects.

12.3 Pharmacokinetics

Absorption — In healthy subjects given subcutaneous doses of HUMULIN N (0.4 unit/kg), median peak serum concentration of insulin occurred at approximately 4 hours (range: 1 to 12 hours) after dosing.

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 — 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. In healthy subjects given subcutaneous doses of HUMULIN N (0.4 unit/kg), the mean apparent half-life was approximately 4.4 hours (range: 1-84 hours).

Specific Populations

The effects of age, gender, race, obesity, pregnancy, or smoking on the pharmacokinetics of HUMULIN N have not been studied.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity and fertility studies were not performed 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.

17 PATIENT COUNSELING INFORMATION

Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use).

Never Share a HUMULIN N KwikPen or Syringe Between Patients

Advise patients that they must never share a HUMULIN N KwikPen with another person, even if the needle is changed. Advise patients using HUMULIN N vials not to share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens [see Warnings and Precautions (5.1)].

Hyperglycemia or Hypoglycemia

Instruct patients on self-management procedures including glucose monitoring, proper injection technique, and management of hypoglycemia and hyperglycemia especially at initiation of HUMULIN N therapy. Instruct patients 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. Instruct patients on the management of hypoglycemia.

Inform patients that their ability to concentrate and react may be impaired as a result of hypoglycemia. Advise patients who have frequent hypoglycemia or reduced or absent warning signs of hypoglycemia to use caution when driving or operating machinery [see Warnings and Precautions (5.3)].

Advise patients that changes in insulin regimen can predispose to hyperglycemia or hypoglycemia and that changes in insulin regimen should be made under close medical supervision [see Warnings and Precautions (5.2)].

Inform patients that accidental mix-ups between insulin products have been reported. Instruct patients to always carefully check that they are administering the correct insulin (e.g., by checking the insulin label before each injection) to avoid medication errors between HUMULIN N and other insulins.

Hypersensitivity Reactions

Advise patients that hypersensitivity reactions have occurred with HUMULIN N. Inform patients on the symptoms of hypersensitivity reactions [see Warnings and Precautions (5.5)].

Instructions for Use

HUMULIN® N KwikPen®

(insulin isophane human)
injectable suspension, for subcutaneous use
3 mL single-patient-use pen (100 units/mL)

Figure

Read the Instructions for Use before you start taking HUMULIN N and each time you get another KwikPen. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

Do not share your HUMULIN N KwikPen with other people, even if the needle has been changed. You may give other people a serious infection or get a serious infection from them.

HUMULIN® N KwikPen® (“Pen”) is a disposable single-patient-use prefilled pen containing 300 units of HUMULIN N. You can give yourself more than 1 dose from the Pen. Each turn (click) of the Dose Knob dials 1 unit of insulin. You can give from 1 to 60 units in a single injection. If your dose is more than 60 units, you will need to give yourself more than 1 injection. The Plunger only moves a little with each injection, and you may not notice that it moves. The Plunger will only reach the end of the cartridge when you have used all 300 units in the Pen.

People who are blind or have vision problems should not use the Pen without help from a person trained to use the Pen.

How to recognize your HUMULIN N KwikPen

Supplies you will need to give your injection

Preparing your Pen

Step 1:
  • Pull the Pen Cap straight off.
    -
    Do not remove the Pen Label.
  • Wipe the Rubber Seal with an alcohol swab.
    -
    Do not attach the Needle before mixing.

Figure
Step 2:
  • Gently roll the Pen between your hands 10 times.

Figure
Step 3:
  • Move the Pen up and down (invert) 10 times.
    Mixing by rolling and inverting the Pen is important to make sure you get the right dose.

Figure
Step 4:
  • Check the liquid in the Pen. HUMULIN N should look white and cloudy after mixing. Do not use if it looks clear or has any lumps or particles in it.
Step 5:
  • Select a new Needle.
  • Pull off the Paper Tab from the Outer Needle Shield.

Figure
Step 6:
  • Push the capped Needle straight onto the Pen and twist the Needle on until it is tight.

Figure
Step 7:
  • Pull off the Outer Needle Shield. Do not throw it away.
  • Pull off the Inner Needle Shield and throw it away.

Figure

Priming your Pen

Prime before each injection.

Step 8:
  • To prime your Pen, turn the Dose Knob to select 2 units.

Figure
Step 9:
  • Hold your Pen with the Needle pointing up. Tap the Cartridge Holder gently to collect air bubbles at the top.

Figure
Step 10:
  • Continue holding your Pen with Needle pointing up. Push the Dose Knob in until it stops, and “0” is seen in the Dose Window. Hold the Dose Knob in and count to 5 slowly.
  • You should see insulin at the tip of the Needle.
    -
    If you do not see insulin, repeat priming steps 8 to 10, no more than 4 times.
    -
    If you still do not see insulin, change the Needle and repeat priming steps 8 to 10.
Small air bubbles are normal and will not affect your dose.

Figure

Figure

Selecting your dose

Step 11:
  • Turn the Dose Knob to select the number of units you need to inject. The Dose Indicator should line up with your dose.
    -
    The Pen dials 1 unit at a time.
    -
    The Dose Knob clicks as you turn it.
    -
    Do not dial your dose by counting the clicks.You may dial the wrong dose. This may lead to you getting too much insulin or not enough insulin.
    -
    The dose can be corrected by turning the Dose Knob in either direction until the correct dose lines up with the Dose Indicator.
    -
    The even numbers (for example, 12) are printed on the dial.
    -
    The odd numbers, (for example, 25) after the number 1, are shown as full lines.
  • Always check the number in the Dose Window to make sure you have dialed the correct dose.

Giving your injection

Step 12:
  • Choose your injection site.
    HUMULIN N is injected under the skin (subcutaneously) of your stomach area, buttocks, upper legs or upper arms.
  • Wipe your skin with an alcohol swab, and let your skin dry before you inject your dose.

Figure
Step 13:
  • Insert the Needle into your skin.
  • Push the Dose Knob all the way in.
  • Continue to hold the Dose Knob in and slowly count to 5 before removing the Needle.

    Figure
Do not try to inject your insulin by turning the Dose Knob. You will not receive your insulin by turning the Dose Knob.

Figure
Step 14:
  • Pull the Needle out of your skin.
    A drop of insulin at the Needle tip is normal. It will not affect your dose.
  • Check the number in the Dose Window.
    -
    If you see “0” in the Dose Window, you have received the full amount you dialed.
    -
    If you do not see “0” in the Dose Window, do not redial. Insert the Needle into your skin and finish your injection.
    -
    If you still do not think you received the full amount you dialed for your injection, do not start over or repeat the injection. Monitor your blood glucose as instructed by your healthcare provider.
    -
    If you normally need to give 2 injections for your full dose, be sure to give your second injection.
The Plunger only moves a little with each injection, and you may not notice that it moves.
If you see blood after you take the Needle out of your skin, press the injection site lightly with a piece of gauze or an alcohol swab. Do not rub the area.

Figure

After your injection

Step 15:
  • Carefully replace the Outer Needle Shield.
