What is Humalog Junior?

Humalog Junior KwikPen is a special insulin pen for managing diabetes in children and adults. It contains rapid-acting insulin lispro to swiftly control blood sugar levels. 

This pen offers precise dosing in half-unit increments, beneficial for those needing small insulin adjustments.

Unlike some pens, Humalog Junior KwikPen doesn’t require refrigeration once in use. Its compact design allows for easy carrying and use anywhere. Remember not to use Humalog in cases of low blood sugar or if allergic to any ingredients.

How Does Humalog Junior Work?

Humalog Junior works by helping your body use sugar from food more effectively. It lowers blood sugar by allowing your muscles and fat to take in sugar from your blood. It also stops your liver from making too much sugar. 

Besides controlling blood sugar, Humalog Junior helps your body store fat and build proteins. This insulin works as well as regular human insulin, but it acts faster to control blood sugar levels right after meals.

Dosage Information and Usage

Dosage Form and Strengths of Humalog Junior

  • Injection: 100 units/mL (U-100)
  • Available as a 3 mL single-patient-use Junior KwikPen® prefilled pen


To use the Humalog Junior KwikPen:

  1. Wipe the pen tip with an alcohol swab and secure the needle.
  2. Select the needed dose.
  3. Disinfect the skin injection site with an alcohol swab.
  4. Pinch the skin and inject it into the pinched area (pinching may not be needed if using a short needle).
  5. Allow a few days before using the same injection site again.

Important Tips:

  • Do not share your Humalog Junior KwikPen, even if you change the needle.
  • Talk to your doctor before switching your insulin type.
  • Insulin doses might need to be adjusted due to sickness, stress, diet changes, more physical activity, or other medications.
  • Regularly check your blood glucose levels as directed by your doctor.
  • Always inject under the skin (subcutaneously) and never into a muscle or vein.
  • Change injection sites frequently to prevent skin issues and avoid areas with lumps.
  • Make sure you are using the correct insulin dosage.
  • If you miss a dose, consult a healthcare professional. Never take an extra dose to make up for a missed one.

How to dispose of Humalog Junior:

  • Place used needles in a sharps container or a plastic container with a secure lid. Avoid discarding needles in household trash.
  • After removing the needle, dispose of the used pen as directed by your healthcare professional.
  • Do not recycle the filled sharps container.
  • Consult your healthcare professional for proper disposal options.


  • If the pen cap is difficult to remove, gently twist it back and forth before pulling it straight off.
  • If the dose knob is tough to push, try pressing it more slowly. If the needle is blocked, replace it with a new one and prime the pen.
  • If the pen contains dust, food, or liquid, discard it and use a new pen.

Storage Information

Keep unused pens in the refrigerator at temperatures between 2°C and 8°C, and do not freeze them. If a pen has been frozen, do not use it. Unused pens stored in the refrigerator can be used until their expiration date. 

The pen you are currently using should be kept at room temperature, up to 30°C, and protected from heat and light. Discard the pen 28 days after starting to use it, even if it contains insulin.

Side Effects of Humalog Junior

Common Side Effects

  • Low blood sugar (hypoglycemia)
  • Reactions at the injection site
  • Skin thickening or pits at the injection site (lipodystrophy)
  • Weight gain
  • Swelling in hands or feet
  • Itching
  • Rash

Serious but Rare Side Effects

  • Severe low blood sugar (hypoglycemia) leading to shakiness and fast heartbeat; may require emergency glucagon treatment
  • Serious allergic reactions with symptoms like rash all over the body, difficulty breathing, and rapid heartbeat
  • Low potassium levels in the blood (hypokalemia)
  • Potential worsening of heart failure symptoms, especially when taking certain diabetes medications called thiazolidinediones (TZDs) alongside Humalog; symptoms include shortness of breath, swelling in ankles or feet, and sudden weight gain

Warnings and Precautions

  • Never Share Insulin Pens or Syringes: Sharing insulin pens or syringes, even with a new needle, can spread blood-borne pathogens and cause serious health risks. Always use your insulin device to avoid infections.
  • Changes in Insulin Regimen and Glycemic Control: Altering the type, strength, or method of insulin injections can affect blood sugar levels, causing hypo- or hyperglycemia. Adjust insulin regimens with medical guidance and closely monitor blood sugar levels to avoid dangerous fluctuations.
  • Hypoglycemia: Low blood sugar can be a common risk with insulin therapy, leading to confusion, shakiness, or worse. It’s important to know the symptoms and have glucose tablets or gel available for emergencies.
  • Medication Errors and Hypoglycemia: Always double-check insulin labels to avoid mistakes that can lead to incorrect dosing and severe hypoglycemia. Never transfer Humalog U-200 from a KwikPen to a syringe to prevent overdosing.
  • Hypersensitivity Reactions: Severe allergic reactions to insulin, like rash or trouble breathing, need immediate medical attention. Stop using Humalog and get medical help right away if you notice these symptoms.
  • Hypokalemia: Insulin therapy, including Humalog, can lower blood potassium levels, potentially causing dangerous hypokalemia. If you’re at risk, monitor your potassium levels closely and report any symptoms to your healthcare provider.
  • Fluid Retention and Heart Failure: Using insulin with TZDs can cause fluid retention and worsen or trigger heart failure. Look out for symptoms like swelling and sudden weight gain, and inform your doctor immediately if they happen.
  • Insulin Pump Device Malfunction: If an insulin pump or infusion set fails, it can cause high blood sugar levels and diabetic ketoacidosis. Have backup insulin methods ready and keep a close eye on your blood sugar if you use an insulin pump.


Administering too much insulin can result in hypoglycemia (low blood sugar) and hypokalemia (low potassium levels). Mild hypoglycemic episodes can typically be managed with oral glucose or adjustments to medication, meal timing, or physical activity. 

In more severe cases leading to coma, seizures, or neurological impairment, emergency interventions such as administering a glucagon product or concentrated intravenous glucose may be necessary. 

Continuous monitoring and sustained carbohydrate intake may be required following treatment, as hypoglycemia can recur even after apparent recovery. 

Drug Interactions With Other Medications

  • Drugs That May Increase the Risk of Hypoglycemia: Certain medications, such as antidiabetic agents, ACE inhibitors, and fibrates, can increase Humalog’s blood sugar-lowering effects, potentially causing hypoglycemia. To avoid low blood sugar, you may need to adjust your Humalog dose and monitor your blood glucose more frequently.
  • Drugs That May Decrease the Blood Glucose Lowering Effect of Humalog: Medications like corticosteroids and some antipsychotics can make Humalog less effective at lowering blood sugar. It’s recommended to adjust the insulin dose and monitor blood glucose levels more closely when using these drugs with Humalog.
  • Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of Humalog: Alcohol, beta-blockers, and lithium salts can either boost or reduce Humalog’s blood sugar-lowering effects. It’s important to closely monitor blood glucose levels and adjust insulin doses as needed when using these drugs with Humalog to maintain good glycemic control.
  • Drugs That May Blunt Signs and Symptoms of Hypoglycemia: Beta-blockers and clonidine can hide the usual signs of low blood sugar, making it harder to spot hypoglycemia quickly. It’s recommended to monitor blood glucose levels more frequently when using these medications with Humalog to catch and manage hypoglycemia early.

Important Considerations to Tell Your Healthcare Provider Before Taking Humalog

  • Medical Conditions: Inform your healthcare provider about any kidney or liver problems you have, as these conditions may affect how your body responds to Humalog.
  • Other Medications: Mention all medications you are currently taking, especially thiazolidinediones (TZDs), as they can interact with Humalog and affect your blood sugar levels.
  • Heart Health: If you have heart failure or other heart problems, discuss this with your healthcare provider. Taking TZDs along with Humalog may worsen heart failure symptoms.
  • Pregnancy: Notify your healthcare provider if you are pregnant or planning to become pregnant. They can help you manage your blood sugar levels effectively during pregnancy.
  • Breastfeeding: If you are breastfeeding or plan to breastfeed, discuss this with your healthcare provider to determine the safest way to manage your blood sugar while taking Humalog and feeding your baby.

Humalog Junior KwikPen is a prefilled insulin pen for kids with diabetes. It provides fast-acting insulin to control blood sugar levels. With half-unit dosing, adjusting doses precisely is simple. No need to refrigerate after first use, making it convenient for insulin administration on the go.

Humalog Junior KwikPen and standard Humalog KwikPen both contain fast-acting insulin, but the Junior version offers the advantage of adjusting insulin doses in half-unit increments. This is particularly beneficial for precise dosing, especially for those who require smaller amounts of insulin.

Humalog should only be mixed with NPH insulin, as combining it with regular insulin or other types is not advised. NPH insulin is an intermediate-acting insulin that boosts glucose uptake in various tissues. Avoid mixing Humalog with regular insulin based on prescribing guidelines.

The frequency of Humalog Junior administration depends on your diabetes management plan, which is determined by your healthcare provider. Typically, it is taken before meals to control blood sugar levels during food intake.

To ensure effective administration of Humalog Junior KwikPen, follow these steps: Clean the injection site, attach a new needle, prime the pen, dial your dose, inject as directed, dispose of the needle safely, and store it as instructed by your healthcare provider. Always consult your provider for guidance on managing diabetes with Humalog Junior KwikPen.

Humalog typically lasts around 4 to 5 hours in your body. Its half-life, which is the time it takes for half of the dose to be eliminated, is about 1 hour. This means that after an hour, half of the Humalog you injected will no longer be active in your system.

Humalog Junior KwikPen contains a total of 300 units of Humalog insulin in a single prefilled disposable pen. This amount allows for multiple doses of insulin to be administered as prescribed by a healthcare provider for managing diabetes.

No, Humalog Junior KwikPen does not need to be refrigerated once it has been opened and is in use. After removing it from the refrigerator and starting to use it, you can store it at room temperature, which should be below 86°F (30°C).

No, you cannot refill a Humalog KwikPen. It is designed as a disposable insulin pen, meaning once you have used up all the insulin inside, you dispose of the entire device. 

The best time to take Humalog Junior KwikPen insulin is within 15 minutes before eating a meal or immediately after starting a meal.
