About Levemir 

Levemir is a form of man-made insulin, a hormone produced in the body. Insulin functions by lowering levels of glucose (blood sugar).

Levemir is used for blood sugar control in adult and pediatric patients with diabetes mellitus. Levemir is available only by prescription. It is available in a generic formulation and under different brand names, including insulin detemir.

Levemir may be prescribed as an injection. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you're prescribed Levemir, complete the entire course of insulin injections unless your doctor specifically tells you to stop. If you don’t complete your prescription, the insulin injections may not fully treat your diabetes mellitus. 

Levemir uses

There are several FDA-approved uses for Levemir, but it may also be used off-label to treat other conditions. Your online medical professional may prescribe it for any of the following common reasons.

It’s also possible that your healthcare provider may prescribe it for other reasons not listed here. If you have questions about why a medication is prescribed, ask your online doctor or pharmacist.

  • Diabetes mellitus

    Levemir is FDA-approved to improve blood sugar levels in adult and pediatric patients with type 1 and type 2 diabetes mellitus. Levemir has a blood glucose-lowering effect that continues working for several hours after injection.

    Levemir is not used to treat diabetic ketoacidosis.

Levemir side effects

  • The side effects associated with taking Levemir are typically mild. Most Levemir side effects are associated with low blood sugar. Levemir has some common side effects. They may include:

    • Hypoglycemia (low blood sugar)

    • Weight gain

    • Swelling in your hands or feet

    • Injection site reactions, such as localized cutaneous amyloidosis

    Other side effects, which are less common but might be more severe, could include:

    • Fluid retention (edema)

    • Low potassium levels

    • Severe hypoglycemia (low blood sugar)

    You should call your doctor if you notice any adverse reactions, or if you develop any other new or concerning symptoms. The use of Levemir is approved for children over two years old with diabetes mellitus.

How to take Levemir

Your pharmacist will provide you with instructions on how to take your Levemir prescription. Be sure to read your prescription label and follow the instructions. Call your doctor or pharmacy if you have any questions.

Levemir can come in different forms and doses, so be sure to follow the specific instructions on your prescription. Levemir is injected under the skin, and your healthcare provider will show you how to properly inject your insulin dose.

Prepare your insulin dose only when you're ready for the injection. Avoid using medication that has changed color, is cloudy, or has particles in it. Your healthcare provider will help you choose the best injection site for your Levemir injection.

If you inject insulin detemir once daily, use the injection at your evening meal or bedtime. If you use it twice daily, use your evening dose at least 12 hours after your morning dose. Your doctor may recommend blood glucose monitoring while you're taking this medication.

What to avoid while taking Levemir

Levemir has 377 drug interactions. Don’t change what you take without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter medicines. 

Possible drug interactions with Levemir include:

  • Other insulin therapy, such as pioglitazone or rosiglitazone

  • Metformin

  • Certain oral contraceptives

  • Medications for mental illness and nausea, including monoamine oxidase inhibitors

Avoid sharing your needles or syringes with others. If you share needles, you may develop a severe infection or get a disease, even if the needle looks clean. Avoid medication errors by carefully checking your insulin detemir before each injection.

Drinking alcohol while taking Levemir can lead to hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar), depending on how much you drink. Avoid alcohol while taking this medication, mainly if you have poorly controlled diabetes.

Medication alternatives to Levemir

If your healthcare provider prefers to put you on another treatment, they may suggest human or other insulin injections in another drug class. Here are some common doctor-recommended alternatives based on your health issue:
