How should I use Humalog KwikPen (insulin lispro)?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended. Insulin lispro is given as an injection (shot) under your skin, using a needle and syringe or an insulin pump. It may also be given through a needle placed into a vein.
You will be shown how to use injections at home. Do not self inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes. Choose a different area of skin in your injection area each time you use this medicine. Do not inject into the same place two times in a row.
Insulin lispro is a fast-acting medicine that begins to work very quickly. After using insulin lispro, you should eat a meal within 5 to 10 minutes.
If you use this medicine with an insulin pump, do not mix or dilute insulin lispro 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. Throw away any medication leftover in the reservoir.
Never share an injection pen or cartridge with another person. Sharing injection pens or cartridges can allow disease such as hepatitis or HIV to pass from one person to another.
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.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.
If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. If your doctor changes your brand, strength, or type of insulin, your dosage needs may change. Do not change your medication dose or schedule without your doctor's advice.
Insulin lispro is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Do not freeze insulin or expose it to high heat or bright light. Do not use any insulin that has been frozen or has been in temperatures above 98 degrees F.
Storing unopened insulin lispro in a refrigerator: Store in the original carton and do not freeze. Throw away unopened insulin if the expiration date on the label has passed.

What happens if I miss a dose?
Since insulin lispro is used before meals, you may not be on a timed dosing schedule. Whenever you use insulin lispro, be sure to eat a meal within 15 minutes. Do not use extra insulin lispro to make up a missed dose.
Use insulin lispro regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
