HumuLIN N KwikPen
Medically reviewed on June 22, 2018
What is HumuLIN N KwikPen?
Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. HumuLIN N KwikPen is an intermediate-acting insulin that starts to work within 2 to 4 hours after injection, peaks in 4 to 12 hours, and keeps working for 12 to 18 hours.
HumuLIN N KwikPen is used to improve blood sugar control in adults and children with diabetes mellitus.
HumuLIN N KwikPen may also be used for purposes not listed in this medication guide.
Never share an injection pen or syringe with another person, even if the needle has been changed.
Before taking this medicine
Do not give HumuLIN N KwikPen to a child without a doctor's advice.
To make sure HumuLIN N KwikPen is safe for you, tell your doctor if you have:
liver or kidney disease; or
low levels of potassium in your blood (hypokalemia).
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 HumuLIN N KwikPen?
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.
HumuLIN N KwikPen must not be given with an insulin pump. Do not inject this medicine into a vein or a muscle.
Your care provider will show you the best places on your body to inject HumuLIN N KwikPen. 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 HumuLIN N KwikPen. Attach a new needle before each use. Do not transfer the insulin from the pen into a syringe.
Never share an injection pen 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.
HumuLIN N KwikPen 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.

Wear a diabetes medical alert tag in case of emergency. Any medical care provider who treats you should know that you have diabetes.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the 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. Symptoms include drowsiness, confusion, blurred vision, numbness or tingling in your mouth, trouble speaking, muscle weakness, clumsy or jerky movements, seizure (convulsions), or loss of consciousness.

Insulin can cause low blood sugar. Avoid driving or operating machinery until you know how HumuLIN N KwikPen will affect you.
Some brands of insulin isophane and syringes are interchangeable, while others are not. Your doctor and/or pharmacist know which brands can be substituted for one another.
Avoid medication errors by always checking the medicine label before injecting your insulin.
Avoid drinking alcohol. It can cause low blood sugar and may interfere with your diabetes treatment.

What other drugs will affect HumuLIN N KwikPen?
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.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
