Drug Information

About Lantus SoloStar (Insulin Glargine)

What is Lantus Solostar?

Lantus Solostar (insulin glargine) is a prescription medication that is classified as a basal (long-acting) insulin. 


What is Lantus Solostar used for? 

It is used for the treatment of type 1 and type 2 diabetes mellitus.

How does it work?

It lowers blood glucose by inhibiting hepatic glucose production, stimulating glucose uptake, and regulating glucose metabolism.


How do I use Lantus Solostar? 

Step 1: Check the label on your SoloSTAR to make sure that you are using the correct insulin.

Step 2: You will need to attach a new needle with each use. Keep the needle as straight as possible when attaching it to your pen. The Lantus SoloSTAR uses screw-on or push-on needles.

Step 3: Perform a safety test to remove any air bubbles and ensure that your pen and needle are working correctly. Select a dose of 2 units. Make sure to always perform a safety test prior to each injection.

Remove the outer needle cap and keep it to remove the needle later after your injection. Then take off the inner needle cap and dispose of it in a sharps container. 

Hold the pen upright, with the need pointing upwards. Gently tap the reservoir to remove any air bubbles that are in the needle. 

Press the injection button all the way inwards and check if any insulin comes out of the needle. If no insulin, check for air bubbles and repeat the safety test two more times. If no insulin comes out a third time, try the safety test again with a new needle.

Step 4: Make sure that the dose window shows “0” after performing the safety test. Then select your prescribed insulin dose in 1-unit steps. If your required dose is > 80 units, you will need to use 2 or more injections.

Step 5: Use the injection method that your doctor or pharmacist showed you. You will either inject the needle subcutaneously in your upper arm, stomach area (abdomen), or thigh (upper leg).

Press the injection button all the way in. Hold the button in that position and slowly count to 10. Then, withdraw the needle.

Step 6: You must remove the needle after each injection and dispose of it appropriately in a sharps container. Place the outer needle cap back on the needle and use it to unscreen the needle from the pen.

Administer the dose prescribed by your doctor. Only administer if the insulin solution is colorless and clear. Avoid administering cold injections. 

Inject subcutaneously into the thighs, abdomen, arms, or buttock. Injection sites should be rotated within the same region to prevent lipodystrophy or localized cutaneous amyloidosis from occurring. Do not inject into skin with lipodystrophy or localized cutaneous amyloidosis.

What is the recommended dosage?

What if I miss a dose?

Pharmacist Tips

  • Write down the date when you start (opened and used) your Lantus vial. Your Lantus vial should be stored in the refrigerator. If unopened and unused, your Lantus vial can be stored until its expiration date. If you have opened and used your Lantus vial, dispose of it after 28 days even if there is insulin left.
  • Do not use your insulin if it is cloudy or has been frozen.
  • Signs and symptoms of hypoglycemia can include: sweating, hunger, dizziness/lightheadedness, blurred vision, fast heart beat, shakiness, trouble concentrating/confusion, slurred speech, anxiety, irritability, or mood changes. 
  • If your blood sugar < 70 mg/dL, that is hypoglycemia. Follow the “Rule of 15” if this occurs: 
    • Consume 15 grams of carbohydrates, which is about 1⁄2 cup of juice or a tablespoon of sugar, honey, or corn syrup. 
    • Then, wait 15 minutes and re-check your blood sugar. If it is still  < 70 mg/dL, repeat the step again. 
    • If the second check is > 70 mg/dL, consume a small portion of protein afterwards.
  • Be sure to check your blood sugar daily and document the readings.
