The Novolog FlexPen is a pre-filled device designed for convenient insulin delivery, aiding in diabetes management. It contains NovoLog, a rapid-acting insulin analog that quickly controls blood sugar levels. Its user-friendly design makes it a common choice for insulin therapy. This guide details the proper and safe steps for using a Novolog FlexPen.
Getting Ready for Injection
Before administering insulin, wash your hands thoroughly with soap and water. Examine your Novolog FlexPen to ensure the insulin is clear and colorless, without particles. Verify the expiration date and discard if expired.
Attach a new, sterile needle (e.g., NovoFine or NovoTwist) by screwing it securely onto the pen. Use a new needle for each injection to ensure sterility and prevent blockages. Remove both the outer and inner needle caps.
Perform a safety prime (an “air shot”) to ensure proper insulin flow and remove air bubbles. Dial 2 units, hold the pen with the needle pointing upward, and gently tap the cartridge to encourage air bubbles to rise. Press the injection button fully until a drop of insulin appears at the needle tip. If no drop appears after six attempts, replace the needle and repeat the priming process.
Performing the Injection
Carefully dial the prescribed insulin units using the dose selector, ensuring the dose counter is at zero before selecting your dose. The FlexPen allows precise one-unit adjustments, providing flexibility for individual insulin needs. If you dial past your dose, the selector can be turned backward without losing insulin.
Choose an injection site from the abdomen, thigh, or upper arm. Consistent rotation of injection sites is important to prevent lipodystrophy, which affects insulin absorption and blood sugar control. Clean the chosen site with an alcohol swab and allow it to air dry completely.
If advised by your healthcare provider, gently pinch the skin. Insert the needle straight into the skin at a 90-degree angle, ensuring it’s fully beneath the surface. Press the injection button firmly until the dose counter returns to “0,” indicating the full dose has been pushed out. Keep pressure on the button and the needle in the skin for at least 6 seconds to ensure complete delivery into the subcutaneous tissue.
Smoothly withdraw the needle straight out from the skin. Avoid rubbing or pressing the injection site immediately after removing the needle to prevent insulin leakage or bruising. Novolog is rapid-acting, typically working within 5 to 10 minutes. Timing with meals is important for effective blood sugar management.
After Injection Steps
Immediately unscrew or detach the used needle from the FlexPen. Remove the needle after each injection to maintain sterility, prevent leakage, and ensure accurate future dosing. Never recap the used needle, as this can lead to accidental needle sticks.
Dispose of the used needle immediately in an FDA-cleared sharps container. If unavailable, use a heavy-duty plastic container with a tight-fitting, puncture-resistant lid (e.g., a laundry detergent bottle) as a temporary solution. Replace the cap on the Novolog FlexPen to protect the insulin and the pen mechanism.
Essential Usage Tips
Proper storage of your Novolog FlexPen maintains insulin effectiveness. Unopened pens should be refrigerated (36-46°F / 2-8°C) until expiration. Once opened or in use, store FlexPens at room temperature (below 86°F / 30°C), away from direct heat and light. Discard them after 28 days, even if some insulin remains.
When traveling, carry your FlexPen in hand luggage if flying. Avoid extreme temperatures. Use an insulated travel case to protect the pen. Bring more insulin and supplies than anticipated for unexpected delays.
Small air bubbles may appear, which priming addresses. A small drop of insulin at the injection site after withdrawal is generally normal. If you experience persistent issues, have concerns about your insulin dose, or notice unusual symptoms, contact your healthcare provider or pharmacist for guidance.
