Questions About Using the Original Prefilled Pen

Prefilled Pen

Insulin does not come out of the needle. What should I do?
To obtain an accurate dose, you must:

  1. Attach a new needle.
  2. Push in the injection button completely (even if a 0 is seen in the window) until a diamond (♦) or an arrow (→) is seen in the center of the dose window.
  3. Prime the Pen.

Note: You may need to prime a new Pen up to six times before a stream of insulin appears.

I dialed the wrong dose (too high or too low). How do I correct the problem?
If you have not pushed in the injection button, simply turn the dose knob backward or forward to correct the dose.

How much insulin is in the Pen?
Each Pen contains a 3 mL (100U/mL) cartridge, which is filled with enough insulin to ensure the delivery of 300 units.

Back to top

I am not sure how much insulin remains in the cartridge. How do I determine this?
Hold the Pen with the needle end pointing down. The scale on the clear cartridge holder (20 units between marks) shows an estimate of the number of insulin units remaining. These numbers should not be used for measuring an insulin dose.

Back to top

What should I do if my full dose cannot be dialed?
The Pen will not allow you to dial a dose greater than the number of insulin units remaining in the cartridge. For example, if you need 31 units and only 25 units remain in the Pen, you will not be able to dial past 25. Do not attempt to dial past this point. (The insulin that remains is unusable and not part of the 300 units.) If a partial dose remains in the Pen you may either:

  1. Give the partial dose and then give the remaining dose using a new Pen, or
  2. Give the full dose with a new Pen.

Back to top

A small amount of insulin remains in the cartridge, but a dose cannot be dialed. Why?
The Pen design prevents the cartridge from being completely emptied. The Pen has delivered 300 units of usable insulin.

What should I do if I cannot completely push in the injection button when priming the Pen or injecting a dose?

  1. Needle is not attached or is clogged.
    1. Attach a new needle.
    2. Push in the injection button completely (even if a "0" is seen in the window) until a diamond (♦) or an arrow (→) is seen in the center of the dose window.
    3. Prime the Pen.
  2. If you are sure insulin is coming out of the needle, push in the injection button more slowly to reduce the effort needed and maintain a constant pressure until the injection button is completely pushed in.

Back to top

Why do I need to prime a new Pen up to six times?
The first time you use a new Pen, priming up to six times may be needed to see a stream of insulin come out of the tip of the needle. If you do not prime until you see a stream of insulin, you may get too much or too little insulin.

How and where should I store my Pen?

  • Pens that have not been used should be stored in a refrigerator but not in a freezer. Do not use a Pen if it has been frozen.
  • After a Pen is used for the first time, it should NOT be refrigerated but should be kept at room temperature [below 86°F (30°C)]and away from direct heat and light.
  • Do not store the Pen with the needle attached. Doing so may allow insulin to leak from the Pen and air bubbles to form in the cartridge. Additionally, with suspension (cloudy) insulins, crystals may clog the needle.
  • Keep the Pen and needles out of the reach of children.

Humalog® Pens should be discarded 28 days after first use. Humalog® Mix75/25™ and Humalog® Mix50/50™ Pens should be discarded 10 days after first use. Be sure to also check the expiration date printed on the Prefilled Pen's label. The date must allow enough time for you to use all the insulin in the Pen.

Indication
Humalog is for use in patients with diabetes to control high blood sugar and should be used with longer-acting insulin, except when used in combination with sulfonylureas in patients with type 2 diabetes.
Humalog, Humalog Mix75/25, and Humalog Mix50/50 are for use in patients with diabetes to control high blood sugar. Humalog should be used with longer-acting insulin, except when used in combination with sulfonylureas in patients with type 2 diabetes.

Humalog (insulin lispro injection [rDNA origin]) is for use in patients with diabetes to control high blood sugar and should be used with longer-acting insulin, except when used in combination with sulfonylureas in patients with type 2 diabetes.

Important Safety Information
Starting or changing insulin therapy should be done cautiously and only under medical supervision.

Humalog should not be used during episodes of low blood sugar (hypoglycemia) or if you are allergic to anything in Humalog.

Humalog is an injectable, fast-acting insulin. Humalog starts working faster than other insulins that contain regular human insulin. Take Humalog within 15 minutes before eating or right after eating a meal. Check your blood sugar levels as told by your healthcare professional.

If you have type 1 diabetes, you need to take a longer-acting insulin in addition to Humalog (except when using an external insulin pump). If you have type 2 diabetes, you may be taking diabetes pills and/or a longer-acting insulin in addition to Humalog.

The safety and effectiveness of Humalog in patients less than 3 years of age have not been established. There are no adequate and well-controlled clinical studies of the use of Humalog in pregnant or nursing women.

Low Blood Sugar
Low blood sugar is the most common adverse effect associated with insulins, including Humalog. Low blood sugar can happen suddenly, and symptoms may be different for each person and may change from time to time. Know your symptoms of low blood sugar. Severe low blood sugar can cause seizures and be life threatening. Follow your healthcare professional's instructions for treating low blood sugar. Talk to your healthcare professional if low blood sugar is a problem for you.

Other Side Effects
Other potential side effects associated with the use of insulins include: low blood potassium, weight gain, changes in fat tissue at the injection site, and allergic reactions. Allergic reactions can happen at the site of injection and over the whole body. Whole-body allergic reactions are less common, but may be life threatening.

Pumps
When used in an external insulin pump, Humalog should not be diluted or mixed with any other insulin. Humalog administration in insulin pumps has not been studied in patients with type 2 diabetes. The infusion set and Humalog should be replaced and a new infusion site selected every 48 hours or less. Glucose monitoring is particularly important for patients using an external insulin pump. Humalog in the external pump should not be exposed to temperatures above 37°C (98.6°F).

Humalog was tested in the MiniMed® Models 506, 507, and 508 insulin pumps using MiniMed® Polyfin® infusion sets.

Humalog was also tested in Disetronic® H-TRONplus® V100 insulin pump (with plastic 3.15 mL insulin reservoir), and the Disetronic D-TRON® and D-TRONplus® insulin pumps (with Humalog 3 mL cartridges) using Disetronic Rapid® infusion sets. A Humalog 3 mL cartridge used in the D-TRON or D-TRONplus should be discarded after 7 days, even if it still contains Humalog. Infusion sets, D-TRON and D-TRONplus cartridge adapters, and Humalog in the external insulin pump reservoir should be discarded every 48 hours or less.

Humalog (insulin lispro injection [rDNA origin]), Humalog Mix75/25 (75% insulin lispro protamine suspension, 25% insulin lispro injection [rDNA origin]), and Humalog Mix50/50 (50% insulin lispro protamine suspension, 50% insulin lispro injection [rDNA origin]) are for use in patients with diabetes to control high blood sugar. Humalog should be used with longer-acting insulin, except when used in combination with sulfonylureas in patients with type 2 diabetes.

Important Safety Information
Starting or changing insulin therapy should be done cautiously and only under medical supervision.

Humalog, Humalog Mix75/25, and Humalog Mix50/50 should not be used during episodes of low blood sugar (hypoglycemia) or if you are allergic to anything in these insulins.

Humalog is an injectable, fast-acting insulin. Humalog Mix75/25 and Humalog Mix50/50 are a mixture of fast-acting and longer-acting insulins. These insulins start working faster than other insulins that contain regular human insulin. Humalog, Humalog Mix75/25, and Humalog Mix50/50 should be taken within 15 minutes before a meal. Humalog can be taken right after eating a meal. Check your blood sugar levels as told by your healthcare professional.

If you have type 1 diabetes, you need to take a longer-acting insulin in addition to Humalog (except when using an external insulin pump). If you have type 2 diabetes, you may be taking diabetes pills and/or a longer-acting insulin in addition to Humalog.

The safety and effectiveness of Humalog in patients less than 3 years of age have not been established. The safety and effectiveness of Humalog Mix75/25 and Humalog Mix50/50 in patients less than 18 years of age have not been established. There are no adequate and well-controlled clinical studies of the use of Humalog, Humalog Mix75/25, or Humalog Mix50/50 in pregnant or nursing women.
