Levemir (insulin detemir) is a long-acting insulin that is used to treat diabetes. The drug helps to lower levels of sugar in the blood. Levemir is part of the insulins drug class and may be used to treat Type 1 diabetes and Type 2 diabetes. Currently, this drug is only available as a brand name drug. Levemir or insulin detemir as some refer to it is a hormone produced in the human's body. Sometimes, it is referred to as a man-made insulin. Doctors recommend it for the treatment of type 2 diabetes in adult patients. Research also indicates that Levemir records remarkable results in the treatment of type 1 diabetes in children above the age of two years, as well as in adults. The drug is different from other forms of insulin. In fact, it is considered long-acting. When applied in patients with either type 1 or type 2 diabetes, Levemir lowers glucose or sugar levels that are present in the blood.
