Insulin detemir is a man-made form of a hormone that is produced in the body. It works by lowering levels of glucose (sugar) in the blood. Insulin detemir is a long-acting form of insulin that is slightly different from other forms of insulin that are not man-made.

Insulin detemir is used to treat diabetes in adults and children.

Insulin detemir may also be used for other purposes not listed in this medication guide.

Many other drugs can potentially interfere with the effects of insulin detemir. It is extremely important that you tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.

Take care to keep your blood sugar from getting too low, causing hypoglycemia. Symptoms of low blood sugar may include headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, or trouble concentrating. Carry a piece of non-dietetic hard candy or glucose tablets with you in case you have low blood sugar. Also be sure your family and close friends know how to help you in an emergency.

Also watch for signs of blood sugar that is too high (hyperglycemia). These symptoms include increased thirst, loss of appetite, fruity breath odor, increased urination, nausea, vomiting, drowsiness, dry skin, and dry mouth. Check your blood sugar levels and ask your doctor how to adjust your insulin doses if needed.
