What is NovoLog FlexPen?
Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. NovoLog FlexPen 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.
NovoLog FlexPen may also be used for purposes not listed in this medication guide.
Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed.
Before taking this medicine
NovoLog FlexPen is not approved for use by anyone younger than 2 years old, and should not be used to treat type 2 diabetes in a child of any age. Fiasp is for use only in adults.
Tell your doctor if you have ever had:
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 NovoLog FlexPen?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
NovoLog FlexPen is injected under the skin, or as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
After using NovoLog FlexPen, you should eat a meal within 5 to 10 minutes.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
If you use an injection pen, use only the pen provided with your medicine. If you use NovoLog FlexPen with an insulin pump, do not mix or dilute NovoLog FlexPen with any other insulin.
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 needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it 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, and feeling 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 dose or medication schedule.
NovoLog FlexPen 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.
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.

Do not use the medicine if it has changed colors or looks cloudy. Call your pharmacist for new medicine.
In case of emergency, wear or carry medical identification to let others know you have diabetes.
What happens if I miss a dose?
Since NovoLog FlexPen is used before meals, you may not be on a timed dosing schedule. Whenever you use NovoLog FlexPen, be sure to eat a meal within 5 to 10 minutes. Do not use extra this 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. 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.
What should I avoid while using NovoLog FlexPen?
Insulin can cause low blood sugar. Avoid driving or operating machinery until you know how NovoLog FlexPen will affect you.
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.
NovoLog FlexPen side effects
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:
heart problems--swelling, rapid weight gain, feeling short of breath; or
Common side effects may include:

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 other drugs will affect NovoLog FlexPen?
Insulin may not work as well when you use other medicines at the same time. Some drugs can also cause you to have fewer symptoms of hypoglycemia, making it harder to tell when your blood sugar is low. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all medicines you start or stop using.
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.
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.
