Levemir Side Effects

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

Levemir is used to treat type 2 diabetes in adults.

Levemir is also used to treat type 1 diabetes in adults and children who are at least 2 years old.

You should not use Levemir if you are allergic to insulin detemir, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with a short-acting insulin).

To make sure you can safely take Levemir, tell your doctor if you have liver or kidney disease, or if you are taking any other medications.

FDA pregnancy category B. Levemir is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. It is not known whether insulin detemir passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Get emergency medical help if you have any of these signs of insulin allergy to Levemir: itching skin rash over the entire body, wheezing, trouble breathing, fast heart rate, sweating, or feeling like you might pass out.
