Humalog U-100 Insulin
You may have been taking a long-acting insulin for a while now. So why did your doctor prescribe another insulin? Well, it’s to help control the blood sugar spikes that happen naturally when you eat. Everyone gets them, but when you have diabetes you may need extra help controlling them. That’s where Humalog comes in.
Humalog is different than your long-acting insulin. Long-acting insulin helps control your blood sugar throughout the whole day.
Humalog is a fast-acting insulin—it helps control the blood sugar spikes that happen naturally when you eat.

Use of Humalog U-100 in an Insulin Pump
For some people, an insulin pump can help improve diabetes management and make it more flexible. A pump may be a good option if any of these apply:
- You regularly test your blood sugar
- You are active and have an inconsistent meal and physical activity schedule
- You have demonstrated the ability to manage your diabetes but don't want to draw attention to it
Have your healthcare team discuss the pros and cons of external insulin pumps with you. They can help you decide whether taking Humalog with an external insulin pump is right for you.
Select Safety Information
Using Humalog or Insulin Lispro Injection (100 units/mL) in an insulin pump may cause serious side effects that can lead to death, such as high blood sugar and ketoacidosis. You can have these serious problems if your insulin pump or infusion set stops working. They can also happen if the insulin in your pump is no longer effective. For these reasons, always keep extra insulin injection supplies with you.
An insulin pump is another way to deliver Humalog U-100 to your body. The insulin pump stores Humalog inside it and has a small, bendable, plastic tube attached at one end. This tube goes into the skin through a small needle. Once the tube is set in place, the needle is removed. To deliver the amount of insulin needed, a button on the pump is pushed. The pump is small enough to be worn on a belt or kept in a pocket.

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:

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.

- sweating
- extreme drowsiness
- swelling of your face, tongue, or throat
- trouble breathing
- a faint feeling

- 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.

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 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.
