Insulin detemir (brand name: Levemir[1]) is a long-acting insulin developed by Novo Nordisk. Levemir is used to maintain the basal level of insulin, and can provide up to 24 hours of blood sugar control, though more commonly closer to 12 hours of coverage. It is typically dosed twice a day. The duration of action is dependent on the dose, with higher doses remaining in the body longer.

Levemir cannot be mixed with other insulins.

Levemir is available in vials for injection, or with a Levemir FlexPen.
