Uses

What is Humalog® (insulin lispro) used for?

Humalog® is a fast-acting insulin that starts to work about 15 minutes after injection, peaks in about 1 hour, and keeps working for 2 to 4 hours. Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood.

Humalog® is used to improve blood sugar control in adults and children with diabetes mellitus.

Humalog® is used to treat type 2 diabetes in adults.

Humalog® is also used to treat type 1 diabetes in adults and children who are at least 3 years old.

How should I take Humalog® (insulin lispro)?

Use Humalog® exactly as it was prescribed for you. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Humalog® is injected under the skin, or into a vein through an IV. 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 needles, IV tubing, and other items used.

After using Humalog®, eat a meal within 15 minutes. If you did not use an injection before the meal, use the medicine right after you eat.

If you use this medicine with an insulin pump, do not mix or dilute Humalog® with any other insulin. Infusion pump tubing, catheters, and the needle location on your skin should be changed every 3 days. Change the medicine in the reservoir every 7 days.

Concentrated Humalog® (200 units/ml) must not be given with an insulin pump, or mixed with other insulins. Do not inject concentrated Humalog® into a vein.

If you use an injection pen, use only the injection pen that comes with Humalog®. A dose counter on the injection pen shows your dose in units. Do not convert your dose. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe or infusion pump.

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.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your insulin dose or schedule.

Humalog® 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.

Keep this medicine in its original container protected from heat and light. Do not draw insulin from a vial into a syringe until you are ready to give an injection. Do not freeze insulin or store it near the cooling element in a refrigerator. Throw away any insulin that has been frozen.
