What is insulin detemir?
Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. Insulin detemir is a man-made long-acting insulin that starts to work several hours after injection and keeps working evenly for 24 hours.
Insulin detemir is used to improve blood sugar control in people with diabetes mellitus.
Insulin detemir is for use in adults and children at least 2 years old.
Insulin detemir is not to be used to treat diabetic ketoacidosis.
Warnings
Never share an injection pen or syringe with another person, even if the needle has been changed.
Before taking this medicine
You should not use insulin detemir if you are allergic to it. Do not use during an episode of hypoglycemia (low blood sugar) or diabetic ketoacidosis (call your doctor for treatment).
To make sure insulin detemir is safe for you, tell your doctor if you have ever had:
-
low levels of potassium in your blood (hypokalemia); or
-
liver or kidney disease.
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 detemir may increase your risk of serious heart problems.
Tell your doctor if you are pregnant or breastfeeding.
Follow your doctor's instructions about using insulin detemir if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications in both the mother and the baby.
How should I use insulin detemir?
Use insulin detemir exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Insulin detemir is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Prepare an insulin detemir injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
Your healthcare provider will show you where on your body to inject insulin detemir. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
Do not inject insulin detemir into skin that is damaged, tender, bruised, pitted, thickened, scaly, or has a scar or hard lump.
If you use insulin detemir once daily, use the injection at your evening meal or at bedtime. If you use the medicine twice daily, use your evening dose at least 12 hours after your morning dose.
Your doctor may want you to also use a short-acting insulin. Always inject your insulins separately. Insulin detemir must not be given with an insulin pump, or mixed with other insulins. Do not inject into a vein or a muscle.
If you use an injection pen, use only the injection pen that comes with insulin detemir. 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 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.
You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).
Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or 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.
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.
Insulin detemir 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 insulin detemir 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.
Storing unopened (not in use) insulin detemir:
-
Refrigerate and use until expiration date; or

Storing opened (in use) insulin detemir:
