Starting hormone therapy can be both exciting and overwhelming, especially when it involves self-injection. Fortunately, Norditropin® FlexPro Pens are designed to make the process as simple, safe, and stress-free as possible. Whether you're just starting HGH therapy or switching to Norditropin from another brand, this guide will walk you through the basics of using the FlexPro pen — safely and effectively.
What Is the FlexPro Pen?
The FlexPro pen is a prefilled, disposable injection device that contains somatropin, the active ingredient in Norditropin. It’s engineered for subcutaneous injection, which means it delivers medication just under the skin, typically in the abdomen or thigh.
Unlike older HGH delivery systems, there's no need to mix powders, calculate doses manually, or handle syringes. Each FlexPro pen is designed for precise, preset dosing based on your doctor’s prescription.
Steps for Safe Use
- Wash your hands thoroughly before handling the pen.
- Inspect the pen to make sure it’s not expired, damaged, or cloudy. It should contain clear, colorless liquid.
- Attach a new needle (usually included with the prescription). Twist it on securely, then remove both caps.
- Prime the pen (if necessary) by releasing a small drop to ensure proper flow.
- Set your prescribed dose by turning the dose selector until the correct number appears.
- Choose your injection site — abdomen, thigh, or the back of the upper arm. Rotate injection sites regularly to avoid irritation.
- Pinch the skin gently and insert the needle at a 90-degree angle.
- Press the injection button and hold it in place for about 5–10 seconds to ensure full delivery.
- Dispose of the needle in a proper sharps container.
Always follow the instructions provided by your physician or pharmacist and review the manufacturer’s official guide.
Storage Tips
- Before first use: Keep the pen refrigerated between 36°F and 46°F (2°C to 8°C).
- After first use: It can be stored at room temperature (up to 77°F or 25°C) for up to 21 days.
- Avoid freezing or exposing the pen to direct heat or sunlight.
Safety & Hygiene
- Never share your pen or needles with anyone else.
- Use a new needle for each injection.
- Don’t reuse or try to refill the pen once it’s empty.
Common Questions from New Users
Does it hurt?
Most users find the injections to be virtually painless, especially with the ultrafine needles that come with the pen.
Can I travel with my pen?
Yes. Just store it properly and bring documentation from your doctor if traveling by air.
What if I miss a dose?
Don’t double up. Simply resume your schedule the next day unless your doctor says otherwise.
Final Tip: The best way to ensure safe and successful HGH therapy is to stay in regular contact with your prescribing physician. Report any side effects or questions immediately, and follow your dosing schedule closely.
With the FlexPro pen, Norditropin® puts simplicity, precision, and safety in your hands — making hormone therapy manageable for beginners and experienced users alike.
