Insulin lispro protamine/insulin lispro is used along with a proper diet and exercise program to control high blood sugar in people with diabetes. This product is a combination of two man-made insulins: intermediate-acting insulin lispro protamine and rapid-acting insulin lispro. This combination starts working faster and lasts for a longer time than regular insulin.
Insulin is a natural substance that allows the body to properly use sugar from the diet. It replaces the insulin that your body no longer produces, thereby lowering your blood sugar. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke.
Read the Patient Information Leaflet if available from your pharmacist before you start using this medication and each time you get a refill. If you have any questions, ask your doctor, diabetes educator, or pharmacist.
Learn all preparation and usage instructions from your health care professional and the product package.
Do not inject cold insulin because this can be painful. The insulin container you are currently using can be kept at room temperature (see also Storage section). Wash your hands before measuring and injecting insulin. Check the product visually for particles, thickening, or clumps before rolling and turning the container. If any are present, discard that container.
To avoid damaging the insulin, do not shake the container. Gently roll and turn it between your palms at least 10 times. If using a cartridge or prefilled syringe, turn it upside down so that the glass ball moves from one end to the other. Gently mix the insulin until it appears evenly white and cloudy. If it does not appear this way, discard it.
The dosage is based on your medical condition and response to treatment. Measure each dose carefully, and use exactly as prescribed by your doctor. Even small changes in the amount of insulin may have a large effect on your blood sugar.
Before injecting each dose, make sure the injection site is clean and dry. Inject this medication under the skin of the abdomen, upper arms, or thighs as directed by your doctor, usually twice daily (15 minutes or less before the morning and evening meal). Do not inject into a vein or muscle. Eat promptly after taking this insulin to avoid low blood sugar (see also Side Effects section). Change where you inject each time to lessen the risk of problems or damage under the skin (for example, pits/lumps or thickened skin). Do not inject into skin that is red, swollen, itchy, or damaged.
Do not mix this product with other insulins or use it in an insulin pump.
Do not change brands or types of insulin without directions on how to do so from your doctor.
Use this medication regularly as directed by your doctor in order to get the most benefit from it. Carefully follow the insulin treatment plan, meal plan, and exercise program your doctor has recommended. Monitor your blood sugar on a regular basis. Keep track of the results, and share them with your doctor. This is very important in order to determine the correct insulin dose.
If you are measuring doses from vials, do not reuse needles and syringes. If you are using the cartridges or pens, use a new needle each time. Do not share your pen device with another person, even if the needle is changed. You may give other people a serious infection, or get a serious infection from them. Learn how to store and discard medical supplies safely.
Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).
Information about Insulin Lispro Protamine (Npl)/Insulin Lispro - Injection
Injection site reactions (such as pain, redness, irritation) or weight gain may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including:
- signs of low potassium level in the blood (such as muscle cramps, weakness, irregular heartbeat)
Too much insulin can cause low blood sugar (hypoglycemia). This effect may also occur if you do not consume enough calories. The symptoms include chills, cold sweats, blurred vision, dizziness, drowsiness, shaking, fast heartbeat, weakness, headache, fainting, tingling of the hands/feet, or hunger. It is a good habit to carry glucose (sugar) tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda. Tell your doctor right away about the reaction. To help prevent low blood sugar, eat meals on a regular schedule and do not skip meals.
Symptoms of high blood sugar (hyperglycemia) include increased thirst/urination. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medication, exercise program, or diet.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
- rash

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs.
Check the labels on all your medicines (such as cough-and-cold products) carefully. Some products may contain sugar or alcohol and may affect your blood sugar. Ask your doctor or pharmacist about using these products safely.
Other medications can affect the results of urine tests for sugar or ketones. Consult your doctor or pharmacist for more information.
