Yes, Norditropin Comes in Pen Form
Norditropin, a brand of somatropin (human growth hormone), is delivered exclusively via prefilled, multi-dose injection pens. These pens—such as Norditropin FlexPro, Norditropin NordiFlex, and Norditropin SimpleXx—allow users to dial exact doses and inject subcutaneously without needing syringes or vials.[1]
How Do Norditropin Pens Work?
Users attach a needle, dial the prescribed dose (from 0.05 mg to 4 mg per injection, depending on the pen model), and press a button to inject. The pens have dose windows for visibility, hidden needles for comfort, and hold 5 mg to 30 mg of solution total. No refrigeration is needed after first use for up to 28 days at room temperature.[1][2]

Who Makes Norditropin Pens?
Novo Nordisk manufactures and markets Norditropin pens worldwide. They dominate the growth hormone market with this pen-exclusive design, approved by the FDA since 1995 for conditions like growth hormone deficiency.[2]
Why Pens Instead of Vials?
Pens reduce dosing errors, improve patient adherence (especially for children), and simplify self-administration compared to traditional vials and syringes. No vial-only version exists today.[1]
Storage and Travel Tips for Norditropin Pens
Keep unopened pens refrigerated (36–46°F). After first puncture, store at up to 77°F for 28 days. Pens are portable but protect from light and freezing. Travel cases are available from Novo Nordisk.[2]
