What is Lantus?

Lantus (insulin glargine) is a long-acting insulin that controls blood sugar levels in adults and children with diabetes mellitus. Diabetes mellitus occurs when the body does not produce enough insulin or cannot properly use insulin, leading to high blood sugar. 

Lantus contains insulin glargine, a man-made insulin that helps maintain steady blood sugar control for up to 24 hours. It is available as a clear, colorless solution in vials or prefilled pens called Lantus SoloStar, making it convenient for diabetes management. 

Lantus is not suitable for treating diabetic ketoacidosis, a serious condition caused by dangerously high blood sugar and insulin deficiency. 

If you are considering Lantus for diabetes treatment, consult your doctor, especially if you have liver or kidney issues, are pregnant, or take medications that could interact with Lantus.

How Does Lantus Work?

Lantus lowers blood sugar levels by regulating glucose metabolism. It contains insulin glargine, a long-acting insulin that helps the body absorb glucose from the bloodstream. 

Lantus stimulates glucose uptake in muscles and fat while reducing glucose production in the liver. It also prevents the breakdown of fats and proteins, helping the body maintain stable energy levels. 

After injection, Lantus provides a steady blood sugar-lowering effect for up to 24 hours, making it a practical option for managing diabetes.

General Instructions for All Lantus Products:

  • Inspect the insulin: Ensure the solution is clear and colorless with no particles. Do not use if discolored or expired.
  • Choose the injection site: Inject subcutaneously into the abdomen, thigh, or upper arm. Rotate injection sites within the same area to avoid skin issues such as lipodystrophy or lumps.

  4. Pull air into the syringe equal to your required dose. Insert the needle into the vial, push the air in, and then withdraw the correct insulin dose. 
  5. Check for air bubbles in the syringe and remove them by tapping the syringe gently.
  6. Pinch the skin, insert the needle, and slowly push the plunger to administer the insulin.
  7. Wait 10 seconds before removing the needle. Then, safely discard the used syringe and needle in a sharps container.

Using the Lantus SoloStar Pen:

  1. Remove the pen cap and attach a new needle. 
  2. Remove the protective caps from the needle. 
  3. Prime the pen by dialing a small dose (1-2 units), pointing the needle upward, and pressing the injection button until insulin appears at the tip. 
  4. Turn the dial to select your prescribed dose, ensuring it matches your specified amount.
  5. Pinch the skin, insert the needle, and press the injection button fully. 
  6. Hold the needle in place for 10 seconds before removing it.

Storage Information of Lantus

Keep unopened Lantus vials and SoloStar pens refrigerated between 36°F and 46°F (2°C to 8°C) and protect them from direct heat and light. 

Do not freeze Lantus, and discard it if frozen. Once opened, the 10 mL multi-dose vial can be stored at room temperature or refrigerated for up to 28 days. 

However, the 3 mL SoloStar prefilled pen should only be stored at room temperature (up to 86°F or 30°C) after opening and used within 28 days.

Side Effects

Common side effects of Lantus insulin include issues like low blood sugar and injection site reactions. However, some individuals may experience severe side effects that require immediate medical attention, such as severe allergic reactions or heart problems.

Common Side Effects

  • Low blood sugar (hypoglycemia)
  • Weight gain
  • Allergic reactions, including redness or swelling at the injection site
  • Skin thickening or pitting at the injection site (lipodystrophy)

Severe Side Effects

  • Severe allergic reactions, such as rash, swelling, or difficulty breathing
  • Low potassium levels in the blood (hypokalemia)
  • Heart failure, especially when used with thiazolidinedione medications (TZDs)
  • Symptoms of worsening heart failure, including shortness of breath, ankle swelling, or sudden weight gain

Warnings and Precautions

Lantus carries important warnings and precautions that patients should be aware of. These include the risk of serious side effects such as hypoglycemia (low blood sugar), allergic reactions, and changes in insulin regimens.

Below is the complete list of warnings and precautions when using Lantus:

  • Never share insulin devices: Lantus SoloStar pens, syringes, or needles should never be shared between patients to avoid transmitting blood-borne diseases.
  • Changes in insulin regimen may cause hypoglycemia or hyperglycemia: Modifying your insulin type, dose, or injection site can affect your blood sugar levels and lead to either low or high blood sugar.
  • Hypoglycemia (low blood sugar) is the most common side effect of insulin use. It can cause dizziness, confusion, or even life-threatening conditions like seizures. Patients must monitor blood glucose levels closely when changing diet, exercise, or medications.
  • Medication errors: Always check the insulin label before each injection to prevent accidental mix-ups with other insulin products.
  • Severe allergic reactions: If you experience symptoms like a rash, difficulty breathing, or swelling, discontinue Lantus immediately and seek emergency care.
  • Hypokalemia (low potassium levels): Insulin may cause potassium to shift within the body, leading to dangerous levels. Regular monitoring of potassium is important, especially in patients at risk.
  • Fluid retention and heart failure: Lantus should be used cautiously with thiazolidinediones (TZDs), as this combination can increase the risk of heart failure. Continuously monitor for signs such as shortness of breath and ankle swelling.

When taking Lantus, monitor your blood sugar levels regularly.

If you are at risk of hypokalemia, take appropriate action to address it.

Monitor your blood sugar levels regularly when taking Lantus to avoid hypoglycemia or hyperglycemia.
