Humalog : Uses, Side Effects, Interactions & More
Why is this medication prescribed?
Humalog (Insulin Lispro) is used to treat type 1 diabetes (a condition in which the body does not make insulin and therefore cannot control the amount of sugar in the blood). It is also used to treat people with type 2 diabetes (a condition in which the body does not normally use insulin and therefore cannot control the amount of sugar in the blood) who need insulin to control their diabetes. In patients with type 1 diabetes, Humalog is always used with another type of insulin, unless it is used in an external insulin pump. In patients with type 2 diabetes, Humalog can be used with another type of insulin or with oral diabetes medications. Humalog is a short-acting artificial version of human insulin. Humalog works by replacing the insulin normally produced by the body and helping to move sugar from the blood to other tissues in the body where it is used for energy. It also prevents the liver from making more sugar.
Over time, people who have diabetes and high blood sugar levels can develop serious or life-threatening complications, such as heart disease, stroke, kidney problems, nerve damage, and eye problems. Using medications, making lifestyle changes (for example, diet, exercise, quitting smoking), and checking your blood sugar regularly can help control your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other complications related to diabetes, such as kidney failure, nerve damage (numbness, cold legs or feet; decreased sexual ability in men and women), eye problems, including vision loss or changes or gum disease. Your doctor and other health care providers will talk to you about the best way to control your diabetes.
How should this medicine be used?
Humalog (Insulin Lispro) comes as a solution (liquid) and a suspension (liquid with particles that will settle at rest) to be injected subcutaneously (under the skin). Humalog solution (Admelog, Humalog) is usually injected within 15 minutes before a meal or immediately after a meal. The Humalog suspension (Humalog Mix 75/25 or Humalog Mix 50/50) should be injected 15 minutes before a meal. Your doctor will tell you how many times you should inject Humalog each day. Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part you do not understand. Use Humalog exactly as directed. Do not use more or less or use it more often than prescribed by your doctor.
Humalog solution can also be injected intravenously (into a vein) by a doctor or nurse in a healthcare setting. A doctor or nurse will monitor you carefully for side effects.
Never use Humalog when you have symptoms of hypoglycemia (low blood sugar) or if you have checked your blood sugar level and found it low. Do not inject insulin into an area of the skin that is red, swollen, itchy, or thickened.
Humalog controls diabetes but does not cure it. Continue to use Humalog even if you feel well. Do not stop using Humalog without talking to your doctor. Do not change to another brand or type of insulin or change the dose of any type of insulin you are using without talking to your doctor. Always check the insulin label to make sure you have received the correct type of insulin from the pharmacy.

Make sure you know what type of container your Humalog comes in and what other supplies, such as needles, syringes, or pens, you will need to inject your medication.
If your Humalog comes in vials, you will need to use syringes to inject your dose. Ask your doctor or pharmacist to show you how to inject Humalog with a syringe. Ask your doctor or pharmacist if you have questions about the type of syringe to use.
If your Humalog comes in cartridges, you will need to purchase a separate insulin pen. Check the manufacturer’s information for the patient to see which pen type is appropriate for the size of the cartridge you are using.

Dispose of needles and syringes in a puncture-resistant container. Ask your doctor or pharmacist how to dispose of the puncture-resistant container.
Your doctor may tell you to mix your Humalog solution with another type of insulin (NPH insulin) in the same syringe. Your doctor will tell you exactly how to do this. Always put Humalog into the syringe first, always use the same brand of syringe, and inject insulin immediately after mixing. Humalog solution should not be mixed with insulin preparations other than NPH insulin. The Humalog suspension should not be mixed with any other insulin preparation.
Your doctor may direct you to dilute Humalog prior to injection to allow easier measurement of your dose. Your doctor will tell you exactly how to do it.

Do not use this type of Humalog if it is colored, cloudy, or contains solid particles. If you are using the Humalog suspension, the insulin should appear cloudy or milky after mixing. Do not use this type of insulin if there are lumps in the liquid or if there are solid white particles sticking to the bottom or the walls of the bottle.

Humalog suspension should be gently shaken or rolled between hands to mix before use. Ask your doctor or pharmacist if the type of insulin you are using should be mixed and how you should mix it if necessary.
Humalog in vials or cartridges can also be used with an external insulin pump. Before using Humalog in a pump system, read the label on the pump to ensure that the pump can be used for continuous delivery of rapid-acting insulin. Read the pump manual for recommended reservoir and tube sets, and ask your doctor or pharmacist to show you how to use the insulin pump. Do not dilute Humalog or mix it with any other type of insulin when using it with an external insulin pump. When using Humalog with an external insulin pump, replace the insulin in the reservoir at least every 7 days and change the infusion set and infusion set insertion site at least every 3 days. tell your doctor and use a different infusion site.
