What is Levemir?

Levemir is a long-acting insulin designed to help manage high blood sugar levels in adults and children with diabetes.

It imitates the natural hormone insulin, which helps the body move sugar from the blood into the cells for energy.

Levemir works slowly to provide steady blood sugar control throughout the day and night.

Levemir is not suitable for treating diabetic ketoacidosis, a serious condition caused by very high blood sugar and ketones in the blood or urine.

How Does Levemir Work?

Levemir lowers blood sugar by increasing glucose absorption by muscles and fat and reducing the amount of sugar the liver produces. Levemir also helps the body store fat and protein more effectively by slowing their breakdown.

This insulin acts steadily over 24 hours without an intense peak, offering consistent blood sugar control.

After injection, Levemir absorbs slowly into the bloodstream and binds to albumin, which helps extend its effects and deliver stable blood sugar management throughout the day.

Dosage Information and Usage

Levemir is available in dosage and forms of 100 units/mL solution in 3 mL FlexPen prefilled pens or 10 mL multiple-dose vials.

As your doctor prescribes, you can use Levemir once or twice daily. Its flexible dosing schedule makes it suitable for personalized diabetes management.

Dosage Form and Strengths of Levemir

Levemir is a clear, colorless solution containing 100 units of insulin detemir per milliliter (U-100). It is available in:

  • 3 mL FlexPen prefilled pens for single-patient use
  • 10 mL multiple-dose vials for repeated use

How to Use Levemir?

Follow these steps for proper use of Levemir:

  • Check if the solution is clear and colorless before injecting.
  • Use the FlexPen or syringe to measure the prescribed amount accurately.
  • Inject subcutaneously into the abdomen, thigh, or upper arm. Rotate injection sites to avoid skin issues.
  • Do not inject into veins or muscles. Avoid areas with lumps, thickened skin, or scars.
  • Keep unused Levemir in the refrigerator and open pens or vials at room temperature.

Side Effects

Levemir may cause both common and severe side effects. Common issues include discomfort at the injection site and weight changes, while more severe effects may include low blood sugar or allergic reactions.

Watch out for any common or severe side effects of Levemir:

Common Side Effects

These are mild side effects that may occur when using Levemir:

  • Reactions at the injection site (redness, swelling, or pain)
  • Skin thickening or pits at the injection site (lipodystrophy)
  • Weight gain
  • Swelling of hands and feet
  • Rash or itching

Severe Side Effects

These side effects are rare but require immediate medical attention:

  • Low blood sugar
  • Severe allergic reactions
  • Low potassium levels (hypokalemia)
  • Heart failure

Warnings and Precautions

  • Do not share your Levemir pen, needle, or syringe. Sharing can spread infections through the blood.
  • Switching the type and method of insulin or where you inject it can impact how well Levemir manages your blood sugar. This might cause low blood sugar (hypoglycemia) or high blood sugar (hyperglycemia).
  • Levemir can cause low blood sugar, which may lead to serious problems like seizures. The risk of hypoglycemia increases if you change your eating habits, exercise more, or take other medications. Symptoms include dizziness, sweating, and confusion.
  • Some people may have severe allergic reactions, including difficulty breathing or swelling of the face and throat. If this happens, stop using Levemir and seek emergency help.
  • Levemir can cause your potassium levels to drop. Low potassium can lead to serious health problems, like heart issues. Your doctor may monitor your potassium levels if you are at risk (e.g., taking other medications that lower potassium).
  • If you are taking Levemir with thiazolidinediones (TZDs), a type of diabetes medicine, it can cause fluid buildup in your body, which may worsen heart failure. You should be monitored for signs of heart failure, such as shortness of breath or swelling in your feet or ankles.

Below is a list of drugs that may interact with Levemir, including those that may increase or decrease its effect on blood sugar levels:

  • Antidiabetic agents (metformin)
  • ACE inhibitors (lisinopril)
  • Angiotensin II receptor blockers (losartan)

  • GLP-1 receptor agonists (liraglutide)
  • DPP-4 inhibitors (sitagliptin)
  • SGLT-2 inhibitors (empagliflozin)
  • Atypical antipsychotics (olanzapine, clozapine)
  • Corticosteroids (prednisone)

Frequently Asked Questions

Levemir (insulin detemir) is a prescription medication used to lower blood sugar in adults and children with type 1 or type 2 diabetes. It is a long-acting insulin administered through subcutaneous injection. It is available in vial, syringe, or prefilled pen forms.

Levemir typically lasts 24 hours, but some people may notice their blood sugar levels rising before the next dose.

Levemir is a long-acting insulin that helps maintain steady blood sugar levels over time, including between meals and overnight.

A Levemir pre-filled pen contains 3 ml of solution, equivalent to 300 units of insulin detemir.

Before using Levemir, inform your doctor about your health history, especially if you have hypoglycemia, low potassium levels, kidney or liver problems, heart failure, or allergies to insulin. Your doctor may closely monitor your potassium, blood sugar, and overall health. Avoid alcohol in excess, as it can affect your blood sugar levels. Levemir is generally safe during pregnancy, but consult your doctor if you are breastfeeding, as its effects on breast milk are not fully known.

Levemir is contraindicated during episodes of hypoglycemia and in patients who are hypersensitive to insulin detemir or any of its ingredients, as this can cause severe reactions like anaphylaxis.

To use Levemir, follow these instructions:

  • Check the insulin label before use.
  • Ensure the solution is clear and colorless.
  • Inject into the thigh, upper arm, or abdomen. Rotate sites within the same area.
  • Avoid injecting into areas with lipodystrophy (abnormal changes in fat tissue) or localized cutaneous amyloidosis (skin conditions caused by abnormal protein deposits).
  • Monitor blood glucose more often when changing your insulin regimen.
  • Do not mix Levemir with other insulins or inject it into veins.
  • Levemir can be given once or twice daily, usually with an evening meal or at bedtime.

Levemir may help some patients with type 2 diabetes reduce their weight. A study showed that it lowers blood glucose levels and decreases body weight. However, it is not specifically approved for weight loss.

Do not mix Levemir with other insulins in the same syringe before injection. Although people often use it with rapid- or short-acting insulin, avoid vigorously shaking or reusing it.

Yes, Levemir can cause hypoglycemia as one of its potential adverse reactions.

Store unopened Levemir at room temperature for up to 42 days, then discard it. Keep opened vials in the refrigerator or at room temperature.

Yes, you can administer Levemir once or twice daily, depending on your needs and glycemic targets. Adjust your dosage and administration of Levemir based on your doctor’s advice.

Overdose of Levemir can lead to severe hypoglycemia, neurological damage, and electrolyte abnormalities, such as low potassium, magnesium, and phosphate levels. It may also cause liver enzyme derangement.

The manufacturer of Levemir is Novo Nordisk.

Inject Levemir under the skin of your stomach area, upper legs, or upper arms. Rotate the injection site with each injection.
