Insulin lispro and insulin lispro-aabc are biologic medications (medications made from living organisms). Biosimilar insulin lispro-aabc injection is highly similar to insulin lispro and works the same way as insulin lispro in the body. Therefore, the term insulin lispro products will be used to represent these medications in this discussion.
Why is this medicine prescribed?
Insulin lispro injection products are used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Insulin lispro injection products are also used to treat people with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) who need insulin to control their diabetes. In patients with type 1 diabetes, insulin lispro injection products are always used with another type of insulin, unless it is used in an external insulin pump. In patients with type 2 diabetes, insulin lispro injection products may be used with another type of insulin or with oral medication(s) for diabetes. Insulin lispro injection products are a short-acting, manmade version of human insulin. Insulin lispro injection products work by replacing the insulin that is normally produced by the body and by helping move sugar from the blood into other body tissues where it is used for energy. They also stops the liver from producing more sugar.
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Using medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease.Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
How should this medicine be used?
Insulin lispro injection products come as a solution (liquid) and a suspension (liquid with particles that will settle on standing) to inject subcutaneously (under the skin). Insulin lispro solution (Admelog, Humalog) is usually injected within 15 minutes before a meal or immediately after a meal. Insulin lispro suspension (Humalog Mix 75/25 or Humalog Mix 50/50) should be injected 15 minutes before a meal. Insulin lispro-aabc solution (Lyumjev) should be injected at the beginning of a meal or within 20 minutes after you start eating a meal.Your doctor will tell you how many times you should inject insulin lispro products 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 insulin lispro injection products exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Insulin lispro injection products may also be injected intravenously (into a vein) by a doctor or nurse in a healthcare setting. A doctor or nurse will carefully monitor you for side effects.
Never use insulin lispro injection products when you have symptoms of hypoglycemia (low blood sugar) or if you have checked your blood sugar and found it to be low.
Insulin lispro injection products control diabetes but do not cure it. Continue to use insulin lispro products even if you feel well. Do not stop using insulin lispro injection products without talking to your doctor. Do not switch 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 received the right type of insulin from the pharmacy.
Insulin lispro injection products come in vials, cartridges that contain medication and are to be placed in dosing pens, and dosing pens that contain cartridges of medication. Be sure you know what type of container your insulin lispro comes in and what other supplies, such as needles, syringes, or pens you will need to inject your medication.
If your insulin lispro injection product comes in vials, you will need to use syringes to inject your dose. Ask your doctor or pharmacist to show you how to inject an insulin lispro injection product using a syringe. Ask your doctor or pharmacist if you have questions about the type of syringe you should use.
If your insulin lispro injection product comes in cartridges, you will need to purchase an insulin pen separately. Check the manufacturer's information for the patient to see what type of pen is right for the cartridge size you are using. Carefully read the instructions that come with your pen, and ask your doctor or pharmacist to show you how to use it. Ask your doctor or pharmacist if you have questions about the type of pen you should use.
If your insulin lispro injection product comes in pens, be sure to read and understand the manufacturer's instructions. Ask your doctor or pharmacist to show you how to use the pen. Follow the directions carefully, and always prime the pen before use.
Never reuse needles or syringes and never share needles, syringes, cartridges, or pens. If you are using an insulin pen, always remove the needle right after you inject your dose. 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 insulin lispro solution with another type of insulin (NPH insulin) in the same syringe. Your doctor will tell you exactly how to do this. Always draw insulin lispro into the syringe first, always use the same brand of syringe, and always inject the insulin immediately after mixing. Insulin lispro injection products should not be mixed with insulin preparations other than NPH insulin. Insulin lispro suspension should not be mixed with any other insulin preparations.
Your doctor may tell you to dilute insulin lispro injection products before injection to allow easier measurement of your dose. Your doctor will tell you exactly how to do this.
You can inject your insulin lispro injection product in your thighs, stomach, upper arms, or buttocks. Change (rotate) the injection site within the chosen area with each dose. Do not inject where the skin is thick, lumpy, tender, bruised, scaly, hard, or into areas of skin where there are scars or skin is damaged.
Always look at your insulin lispro product before you inject it. If you are using insulin lispro solution, the insulin should be clear and colorless. Do not use this type of insulin lispro product if it is colored, cloudy, or contains solid particles. If you are using insulin lispro suspension, the insulin should appear cloudy or milky after you mix it. Do not use this type of insulin product if there are clumps in the liquid or if there are solid white particles sticking to the bottom or walls of the bottle. Do not use any type of insulin after the expiration date printed on the bottle has passed.
Insulin lispro suspension must be gently shaken or rolled between your 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.
Insulin lispro solution (Admelog, Humalog U-100, Lyumjev U-100) also can be used with an external insulin pump. Before using insulin lispro products in a pump system, read the pump label to make sure the pump can be used for continuous delivery of fast-acting insulin. Read the pump manual for recommended reservoir and tubing sets, and ask your doctor or pharmacist to show you how to use the insulin pump. Do not dilute insulin lispro or mix it with any other type of insulin when using it with an external insulin pump. When using insulin lispro products with an external insulin pump, replace the insulin in the reservoir at least every 7 days (Admelog, Humalog U-100,) or at least every 9 days (Lyumjev U-100), and change the infusion set and infusion set insertion site at least every 3 days. If the infusion site is red, itchy, lumpy, or thickened, tell your doctor and use a different infusion site.
When using insulin lispro solution in an external insulin pump, high blood sugar may occur quickly if the pump stops working properly or if the insulin in the pump reservoir is exposed to direct sunlight or temperatures greater than 98.6°F (37°C). High blood sugar may also occur if the tubing leaks or becomes blocked, disconnected, or kinks. If the problem cannot be found quickly and corrected, call your doctor right away. You may need to temporarily use insulin by subcutaneous injection (using syringes or an insulin pen). Make sure you have back-up insulin and any necessary supplies on hand, and ask your doctor or pharmacist to show you how to use them.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to insulin lispro injection products. Your doctor will also tell you how to check your response to insulin lispro injection products by measuring your blood sugar levels at home. Follow these instructions carefully.
You should always wear a diabetic identification bracelet to be sure you get proper treatment in an emergency.
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.
