Levemir Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Levemir is a brand name. Its generic name is Insulin Detemir.


Levemir is an insulin analog that is used as a long-acting insulin for adults and children with diabetes mellitus. It has a "tail" attached to it that binds to body tissues and slows the absorption and action of insulin. This helps it to provide more even levels of blood glucose control for up to 24 hours.

Uses for

Levemir is used to lower blood glucose in people who have type 1 diabetes (diabetes mellitus) and to help control blood glucose levels in people who have type 2 diabetes. It is usually used together with a short-acting insulin that is taken before meals.

Mechanism of Action

Levemir works by stimulating the uptake of glucose into cells, increasing the production of glycogen, and inhibiting the production of glucose by the liver. It also helps to reduce ketoacidosis (high levels of ketones in the blood due to an insufficiency of insulin).

How Long Does It Take To Work

Levemir typically begins to work after 30 minutes and can be effective for up to 24 hours.


Levemir is slowly absorbed by the body, with peak levels typically occurring between 6 and 8 hours after administration.

Route of Elimination

Levemir is eliminated from the body by renal excretion and metabolism in the liver.


Dosage of Levemir is individualized and based on the needs and response of the patient. The usual starting dose for adults with type 1 diabetes is 8–16 U per day. The dosage should be adjusted according to the patient's blood glucose levels, usually every five to 10 days.


Levemir can be taken either subcutaneously by injection or by an insulin pump.

Side Effects

Common side effects of Levemir include hypoglycemia (low blood sugar), weight gain, headaches, nausea, and injection site reactions.


Levemir is considered to be well tolerated, however high doses may lead to hypoglycemia (low blood sugars).


Patients taking Levemir should monitor their blood glucose levels regularly and follow instructions for proper injection techniques. Additionally, patients should monitor for side effects such as hypoglycemia, weight gain, or injection site reactions.
