What is insulin lispro and insulin lispro protamine?
Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. Insulin lispro is a fast-acting insulin. Insulin lispro protamine is an intermediate-acting insulin. This combination insulin starts to work within 10 to 20 minutes after injection, peaks in 2 hours, and keeps working for up to 24 hours.
Insulin lispro and insulin lispro protamine may also be used for purposes not listed in this medication guide.
What are the possible side effects of this medicine?
Get emergency medical help if you have signs of insulin allergy: redness or swelling where an injection was given, itchy skin rash over the entire body, trouble breathing, fast heartbeats, feeling like you might pass out, or swelling in your tongue or throat.
Call your doctor at once if you have:
- fluid retention--weight gain, swelling in your hands or feet, feeling short of breath; or
- low potassium--leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling.
Common side effects may include:
- low blood sugar;
- itching, mild skin rash; or
- thickening or hollowing of the skin where you injected the medicine.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the most important information I should know about this medicine?
Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed.
What should I discuss with my healthcare provider before using this medicine?
You should not use this medicine if you are allergic to insulin lispro, or if you are having an episode of hypoglycemia (low blood sugar).
Insulin lispro and insulin lispro protamine is not approved for use by anyone younger than 18 years old.
To make sure this medicine is safe for you, tell your doctor if you have:
Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes contained in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while you are using insulin may increase your risk of serious heart problems.
Follow your doctor's instructions about using insulin if you are pregnant or breast-feeding a baby. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester of pregnancy. Your dose needs may also be different while you are breast-feeding.
How should I use this medicine?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Insulin is injected under the skin. You will be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes. Do not inject insulin lispro and insulin lispro protamine into a vein.
Use this medication within 15 minutes before eating a meal.
Your care provider will show you the best places on your body to inject this insulin. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
If you use an injection pen, use only the injection pen that comes with insulin lispro and insulin lispro protamine. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.
Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or disease to pass from one person to another.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Insulin is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Since this medicine is used before meals, you may not be on a timed dosing schedule. Whenever you use the medicine, be sure to eat a meal within 15 minutes. Do not use extra medicine to make up a missed dose.
Keep insulin on hand at all times. Get your prescription refilled before you run out of medicine completely.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Insulin overdose can cause life-threatening hypoglycemia.

What should I avoid while using this medicine?

What other drugs will affect insulin lispro and insulin lispro protamine?
Many other medicines can affect your blood sugar, and some medicines can increase or decrease the effects of insulin. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using. This includes prescription and over-the-counter medicines, vitamins, and herbal products.
