How To Use The Lantus SoloStar Insulin Pen?

Whether you’re new to insulin injection pens or switching from another one, it’s essential to learn how to use the Lantus SoloStar pen correctly. Follow these step-by-step instructions for safe and accurate insulin delivery.

Step 1: Gather Your Supplies

Before you begin, ensure you have all the necessary supplies: the Lantus Solostar Pen, a new disposable needle, an alcohol swab, and a sharps container for safe needle disposal.

Step 2: Prepare the Pen

Remove the pen cap and check the insulin for any abnormalities. Gently roll the pen between your palms to mix the insulin, being careful not to shake it vigorously.

Step 3: Attach a New Needle

Twist off the protective cap from the new disposable needle and screw it onto the pen firmly but not overtight. Ensure the needle is straight and securely attached.

Step 4: Prime the Pen

Set the dose selector to 2 units and hold the pen with the needle pointing upwards. Tap the cartridge gently to remove any air bubbles, then press the injection button until a drop of insulin appears at the needle tip.

Step 5: Choose the Dose

Set your prescribed dose by turning the dose selector clockwise or counterclockwise. Always consult your healthcare provider for the correct dosage.

Step 6: Inject the Insulin

Select the injection site, typically the fatty tissue of your abdomen or thigh. Clean the area with an alcohol swab, then pinch the skin and insert the needle at a 90-degree angle. Push the injection button down and hold it for at least 10 seconds to ensure the full dose is delivered.

Step 7: Remove the Needle

Carefully remove the needle from your skin and dispose of it in a sharps container. Do not recap the needle.

Always follow your healthcare provider’s instructions and consult them if you have any concerns or questions. Remember to rotate your injection sites, keep track of your insulin doses, and maintain good hygiene throughout the process. The Lantus Solostar Insulin Pen is designed to make insulin administration as convenient and safe as possible, empowering you to manage your diabetes effectively.

What’s The Right Amount Of Lantus Dosage For You?

Your doctor would make adjustments to your Lantus insulin dosage gradually based on factors like your blood sugar testing results or your blood sugar goal number. This process is known as titration. You’ll likely need to fine-tune your dose every 3 to 4 days until you find the optimal amount for your needs.

What Are The Side Effects Of Lantus?

While Lantus Insulin effectively manages blood sugar levels, it is essential to be aware of potential side effects. The most common side effects of Lantus include:

  1. Hypoglycemia (low blood sugar)
  2. Weight gain
  3. Headaches
  4. Upper respiratory infections
  5. Redness, itching or swelling

On the other hand, rare but serious side effects may include severe allergic reactions, heart failure, and hypokalemia (low potassium levels). It is essential to consult with your healthcare provider if you experience any unusual or severe side effects while using Lantus. They can provide guidance and determine the best course of action for you.

Can I Mix Lantus With Any Other Insulin?

No, you shouldn’t mix Lantus insulin with other insulin or injectable medication within the same syringe. Combining these substances can lead to unpredictable changes in the properties of Lantus, potentially causing inadequate blood sugar control.

Prescription Lantus Solostar Pen uses long-acting insulin used to treat adults with type 2 diabetes and adults and pediatric patients (children 6 years and older) with type 1 diabetes for the control of high blood sugar.

  • Do not use Lantus Solostar Pen to treat diabetic ketoacidosis.

Important Safety Information

Do not use Lantus Solostar Pen during episodes of low blood sugar or if you are allergic to insulin or any of the inactive ingredients in Lantus.

Do not share needles, insulin pens, or syringes with others. Do NOT reuse needles.

Before starting Lantus, tell your doctor about all your medical conditions, including if you have liver or kidney problems, if you are pregnant or planning to become pregnant or if you are breast-feeding or planning to breast-feed.

Change (rotate) your injection sites within the area you chose with each dose to reduce your risk of getting lipodystrophy (pitted or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the injection sites. Do not use the same spot for each injection or inject where the skin is pitted, thickened, lumpy, tender, bruised, scaly, hard, scarred or damaged.

Heart failure can occur if you are taking insulin together with certain medicines called TZDs (thiazolidinediones), even if you have never had heart failure or other heart problems. If you already have heart failure, it may get worse while you take TZDs with Lantus. Your treatment with TZDs and Lantus may need to be changed or stopped by your doctor if you have new or worsening heart failure. Tell your doctor if you have any new or worsening symptoms of heart failure, including:

  • Shortness of breath
  • Swelling of your ankles or feet
  • Sudden weight gain

Tell your doctor about all the medications you take, including OTC medicines, vitamins, and supplements, including herbal supplements.

Lantus should be taken once a day at the same time every day. Test your blood sugar levels while using insulin, such as Lantus. Do not make any changes to your dose or type of insulin without talking to your healthcare provider. Any change of insulin should be made cautiously and only under medical supervision.

Do NOT dilute or mix Lantus with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Lantus must only be used if the solution is clear and colorless with no particles visible. Always make sure you have the correct insulin before each injection.

While using Lantus, do not drive or operate heavy machinery until you know how Lantus affects you. You should not drink alcohol or use other medicines that contain alcohol.

The most common side effect of insulin, including Lantus, is low blood sugar (hypoglycemia), which may be serious and life threatening. It may cause harm to your heart or brain. Symptoms of serious low blood sugar may include shaking, sweating, fast heartbeat, and blurred vision.

Lantus may cause serious side effects that can lead to death, such as severe allergic reactions. Get medical help right away if you have:

  • A rash over your whole body
  • Trouble breathing
  • A fast heartbeat
  • Sweating
  • Swelling of your face, tongue, or throat
  • Shortness of breath
  • Extreme drowsiness, dizziness, or confusion

Other possible side effects may include swelling, weight gain, low potassium levels, injection site reactions, including changes in fat tissue at the injection site, and allergic reactions.
