Humulin® R U-100Short-acting insulin to cover blood sugar increases from meals eaten within 30 minutes

Humulin is similar to the insulin the body makes naturally. Introduced by Eli Lilly and Company in 1982, Humulin U-100 insulins are affordable choices that celebrate over 30 years of helping people manage type 1 and type 2 diabetes.

For the treatment of high blood sugar (glucose) levels, 3 types of Humulin U-100 insulin can help manage diabetes. Each type varies in how fast it starts working and how long the effects last. Keep in mind that insulin should only be used under a healthcare provider’s advice and care.

What is Humulin R U-100?

Humulin R U-100 is a short-acting insulin, which means it can cover insulin needs for meals eaten within 30 minutes.

There are 2 types of Humulin R insulin: Humulin R U-100 and a more concentrated insulin, Humulin R U-500. U-100 insulins, including Humulin R, contain 100 units per mL. It’s important to make sure you have the correct one.

Humulin R U-100 is for injection under the skin. It should not be injected into the muscle. Doses of insulin are measured in units. With Humulin R U-100, it is important to use a syringe that is marked for U-100 insulins.

Do not use Humulin R U-100:

  • If it appears cloudy, thickened, or slightly colored, or
  • If solid particles are visible

If you notice your insulin requirements changing, talk to your doctor.

Be sure to read the Patient Information that comes with your Humulin R U-100 insulin.

Also be sure to read the Instructions for Use for your Humulin R U-100 vial.

To learn more about Humulin R U-100, call The Lilly Answers Center at 1-800-LillyRx (1-800-545-5979).

Pens and needles are for single-patient use only and should not be shared, even in healthcare facilities, as infection or disease can be spread from one person to another.

Do not withdraw insulin from the pen using a syringe.

Indication

Humulin R U-100 is indicated as an adjunct to diet and exercise to improve glycemic control in adults and children with type 1 and type 2 diabetes mellitus.

Important Considerations for Use for Humulin R U-100, Humulin N, and Humulin 70/30:

  • Low blood sugar (hypoglycemia) is the most common side effect of insulin, including Lilly Humulin insulins. Signs of severe hypoglycemia can include: disorientation, unconsciousness, seizures, or death.
  • Humulin KwikPens must never be shared, even if the needle is changed. If you use Humulin vials, you must never share needles or syringes with another person. Sharing poses a risk that you may give someone a serious infection or get a serious infection from them.
  • Any change of insulin should be made cautiously and only under medical supervision.
  • Changes in strength, manufacturer, type (eg, regular, NPH, analog), species, or method of manufacture may result in the need for a change in dosage.
  • Some patients taking Humulin may require a change in dosage from that used with other insulins. If an adjustment is needed, it may occur with the first dose or during the first several weeks or months.
  • High blood sugar (hyperglycemia) may develop if the body has too little insulin. In people with type 1 or insulin-dependent diabetes, prolonged hyperglycemia can result in diabetic ketoacidosis (DKA). DKA is a life-threatening emergency.
  • Always check the carton and bottle label for the name and letter designation of the insulin received from the pharmacy to make sure it’s the correct insulin.
  • Do not use any other insulin except on your healthcare provider's advice and direction.
  • Do not use Humulin after the expiration date stamped on the label or if it has been frozen.
  • Do not share needles or syringes, because you may give or get an infection.
  • Before using Lilly Humulin insulin, tell your healthcare providers about all of your medical conditions, including liver, kidney, or heart problems, if you are pregnant or breast-feeding, and about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.
  • Serious side effects can include heart failure when taking certain pills called thiazolidinediones or “TZDs” with Lilly Humulin insulin. Tell your healthcare provider if you have any new or worse symptoms of heart failure, such as shortness of breath, swelling of your ankles or feet, or sudden weight gain.

Important Safety Information for Humulin R U-500

Contraindications

  • Humulin R U-500 is contraindicated during episodes of hypoglycemia and in patients hypersensitive to Humulin R U-500 or any of its excipients.

Warnings and Precautions

  • Dosing Errors: Extreme caution must be observed in measuring the dose of Humulin R U-500 because inadvertent overdose may result in serious adverse reaction or life-threatening hypoglycemia.

Medication errors associated with the Humulin R U-500 vial have occurred and resulted in patients experiencing hyperglycemia, hypoglycemia, or death.

Dispensing

  • Instruct patients to always inspect insulin vials to confirm that the correct insulin is dispensed including the correct brand and concentration.
  • The Humulin R U-500 vial, which contains 20 mL, has a band of diagonal brown stripes. “U-500” is also highlighted in red on the Humulin R U-500 vial label.

Prescribing

  • When using a U-100 insulin syringe or tuberculin syringe, express the prescribed dose of Humulin R U-500 in units of insulin along with the appropriate corresponding markings on the syringe the patient is using.

Administration

  • Instruct patients to always check the insulin label before each injection.
  • A majority of the medication errors with Humulin R U-500 vial occurred due to dosing confusion when the dose was prescribed in units or volume corresponding to a U-100 syringe or tuberculin syringe markings, respectively, or the prescribed dose was administered without recognizing that the markings on the syringe used do not directly correspond to the U-500 dose. Instructions for use should always be read and followed before use.
  • Instruct the patient to inform hospital or emergency department staff of the dose of Humulin R U-500 prescribed.
  • A conversion chart should always be used when administering doses from the Humulin R U-500 vial with U-100 insulin syringes or 1 mL tuberculin syringes.

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).

DO NOT transfer Humulin R U-500 from the Humulin R U-500 KwikPen into a syringe for administration. Overdose and severe hypoglycemia can occur.

  • Patients Should Never Share KwikPens, Needles, or Syringes with Other People, even if the needle is changed. 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 should be made cautiously and only under medical supervision and the frequency of blood glucose monitoring should be increased.
  • 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, such as driving or operating other machinery.

Hypoglycemia can happen suddenly and symptoms may differ in each individual and change over time in the same individual.

Early warning symptoms 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, or in patients who experience recurrent 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.

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.

  • Hypersensitivity and Allergic Reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including Humulin R U-500. If hypersensitivity reactions occur, discontinue Humulin R U-500; treat per standard of care and monitor until symptoms and signs resolve.
  • Hypokalemia: Insulin use can lead to hypokalemia that left untreated may cause respiratory paralysis, ventricular arrhythmia, 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 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. Observe patients 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.

Adverse Reactions

  • Adverse reactions include hypoglycemia, allergic reactions, lipodystrophy, injection site reactions, weight gain, peripheral edema, and immunogenicity.

Drug Interactions

  • Some medications may alter glucose metabolism and may necessitate insulin dose adjustment. Signs of hypoglycemia may be reduced or absent in patients taking antiadrenergic drugs. Particularly close monitoring may be required.

Use in Specific Populations

  • Pregnancy Category B: 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.
  • 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.
  • Geriatric Use: There are no well-controlled studies of use of Humulin R U-500 in geriatric patients. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemia.
