What to know about Lilly's Portfolio of Non-Branded Insulins

Insulin Lispro Injection U-100 Vial (100 units/mL) and KwikPens®
Insulin Lispro Injection 100 units/mL logo


Because it’s the same molecule as Humalog® (insulin lispro injection), Lilly’s Insulin Lispro Injection U-100 helps control the blood sugar spikes that happen naturally when you eat. Lilly’s Insulin Lispro Injection U-100 (a fast-acting insulin) works to manage those blood sugar spikes and may help keep your sugar levels in balance. Lilly’s Insulin Lispro Injection U-100 is taken within 15 minutes before eating or right after eating a meal.

Insulin Lispro Injection is different than your long-acting insulin. Long-acting insulin helps control your blood sugar throughout the whole day. It's important to talk to your doctor about when and how often you should check your blood sugar levels.

Select Safety Information

Do not take Humalog or Insulin Lispro Injection if you have symptoms of low blood sugar (hypoglycemia) or an allergy to insulin lispro products or any of their ingredients.

The Insulin Lispro Injection U-100 KwikPen is a small, lightweight pen that's prefilled with mealtime insulin. Since it shouldn't be refrigerated after the first use*, you can take it just about anywhere. You can carry it in a purse or slip it into a jacket or coat pocket. It's a good idea to always carry an extra pen.

*Once you start using Insulin Lispro Injection U-100 KwikPen, it should be stored at room temperature, below 86˚F (30˚C), and must be used within 28 days or be discarded, even if it still contains Insulin Lispro Injection U-100.

Select Safety Information

Do not reuse needles or share your insulin injection supplies with other people. This includes your prefilled pen for use by a single patient, cartridges, reusable pen that works with Lilly 3 mL cartridges, needles, and syringes. You or the other person can get a serious infection. This can happen even if you change the needle.

Lilly’s Insulin Lispro Injection U-100 may be injected under your skin in the stomach area, the back of your upper arms, upper legs, or buttocks (see diagram). Never inject Lilly’s Insulin Lispro Injection U-100 into a muscle or vein. Ask your doctor for help determining the most appropriate injection sites for you.

Be sure to use a different injection site each time and do not overuse any site.

Select Safety Information

Do not change the type of insulin you take or your dose, unless your doctor tells you to. This could cause low or high blood sugar, which could be serious. Do not inject your insulin into the exact same spot or where the skin has pit or lumps. Avoid injecting into thickened, tender, bruised, scaly, hard, scarred, or damaged skin.

Blood sugar variations

When you track your blood sugar every day, you will probably see different numbers all the time. These variations in your blood sugar from day to day are normal.

Your blood sugar varies based on stress, what you eat, other medications, exercise, and other factors. Don’t be discouraged by changes in your blood sugar. With your doctor’s input, these variations may provide learning opportunities.



Select Safety Information

Humalog and Insulin Lispro Injection may cause serious side effects that can lead to death, such as low blood sugar. Low blood sugar can cause dizziness or light-headedness, sweating, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, anxiety, irritability, mood change, and hunger. If you are at risk of having severely low blood sugar, your doctor may prescribe a glucagon emergency kit. These are used when your blood sugar becomes too low and you are unable to take sugar by mouth. Glucagon helps your body release sugar into your bloodstream.

Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 KwikPen (100 units/mL) logo


Lilly’s Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 is a combination of fast- and longer-acting insulins that work together to help manage your blood sugar between meals and at night, as well as blood sugar spikes that can happen when you eat.

Note that Lilly’s Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 starts working faster than other insulins that contain regular human insulin.

It's important to take Lilly’s Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 within 15 minutes before eating a meal to help prevent low blood sugar.

Select Safety Information

Insulin mixes—such as Lilly’s Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 KwikPen—combine fast-acting and longer-acting insulins to give you the benefit of both insulins.

Lilly’s Insulin Lispro Injection Junior KwikPen is an insulin pen that offers the combined benefits of a prefilled disposable pen with rapid-acting insulin and half-unit dosing.

Warnings

Do not take Humalog, Insulin Lispro Injection, Humalog Mix50/50, Humalog Mix75/25, or Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 if you have:

  • symptoms of low blood sugar (hypoglycemia)

  • prefilled pen for use by a single patient
  • cartridges
  • reusable pen that works with Lilly 3 mL cartridges
  • needles
  • syringes

You or the other person can get a serious infection. This can happen even if you change the needle.

Do not change the type of insulin you take or your dose, unless your doctor tells you to. This could cause low or high blood sugar, which could be serious.

Humalog, Insulin Lispro Injection, Humalog Mix50/50, Humalog Mix75/25, and Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 may cause serious side effects. Some of these can lead to death. The possible serious side effects are:

  • Low blood sugar. This can cause:
    • dizziness or light-headedness
    • headache
    • shakiness
    • irritability
    • sweating
    • blurred vision
    • fast heartbeat
    • mood change

  • Heart failure. Taking diabetes pills called thiazolidinediones (thIE-uh-zOH-li-dEEn-dIE-OHns), or “TZDs,” with insulin lispro products may cause heart failure in some people. This includes people who do not have any heart problems. If you have heart failure, it may get worse if you take TZDs with these insulin lispro products. Tell your doctor if you have any new symptoms of heart failure, or if they get worse. Some symptoms of heart failure include: shortness of breath, swelling of ankles and feet, and sudden weight gain. Your doctor may need to change or stop treatment with TZDs and your insulin lispro product.
  • High blood sugar and ketoacidosis. You can have these serious problems when your insulin pump or infusion set stops working. They can also happen if your insulin is no longer effective. For these reasons, always keep extra insulin injection supplies with you.

These are not all of the possible side effects. Tell your doctor if you have any side effects. You can report side effects at 1-800-FDA-1088 or www.fda.gov/medwatch.

Before Using

Talk with your doctor about low blood sugar and how to manage it. Also tell your doctor:

  • about all of the medicines you take, including over-the-counter medicines, vitamins, and herbal supplements.
  • about any other prescription medicines you take, especially ones called TZDs.
  • about all of your medical conditions, including if you have heart failure or other heart, liver, or kidney problems.
  • if you are pregnant, breastfeeding, or plan to become pregnant or breastfeed.

How to Take

Read the Instructions for Use that come with your Humalog, Insulin Lispro Injection, Humalog Mix50/50, Humalog Mix75/25, or Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25. Be sure to take your insulin lispro product and check your blood sugar levels exactly as your doctor tells you to. Your doctor may tell you to change your dose because of illness, increased stress, or changes in your weight, diet, or physical activity level. He or she may also tell you to change the amount or time of your dose because of other medicines or different types of insulin you take.

Before injecting your insulin lispro product

You can inject your insulin dose yourself, or you can have a trained caregiver inject it for you. Make sure you or your caregiver:

  • Check the insulin label before each injection. This will help you make sure that you are taking the correct insulin.
  • Use a new needle for each injection. You can get a serious infection or the wrong dose of insulin if you re-use needles.
  • Change (rotate) where you inject your insulin with each dose. This can reduce your chance of getting pits, lumps, or thickened skin where you inject your insulin. Do not inject your insulin into the exact same spot or where the skin has pits or lumps. Avoid injecting into thickened, tender, bruised, scaly, hard, scarred, or damaged skin.

When you are ready to inject

  • If you are taking Humalog or Insulin Lispro Injection, inject it under your skin within 15 minutes before or right after you eat a meal.
  • If you are taking Humalog Mix50/50, Humalog Mix75/25, or Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25, inject it under your skin within 15 minutes before you eat a meal.

Staying safe while taking your insulin lispro product

To stay safe while taking your insulin, be sure to never inject Humalog U-200, Humalog Mix50/50, Humalog Mix75/25, or Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 in your vein, muscle, or with an insulin pump. Also be sure not to:

  • mix Humalog U-200, Humalog Mix50/50, Humalog Mix75/25, or Insulin Lispro Protamine and Insulin Lispro Injectable Suspension Mix75/25 with other insulins or liquids.
