Norditropin: if you take 0.2mg from the green pen; how much do you take from the orange pen!?

Short answer:
If you normally use a 0.2 mg dose from the green Norditropin pen, you would still take 0.2 mg of the drug from the orange pen. The difference is only in how much liquid you have to draw.

Why that matters

How it works in practice

• Same active dose – Whether you’re using the green or the orange pen, the goal is to deliver the same amount of somatropin (0.2 mg).
• Different volumes – The orange pen contains a higher concentration, so you’ll need to withdraw a smaller volume (about 0.02 mL if the pen is 10 mg/mL) to achieve 0.2 mg.
• Device instructions – Most pens have a built‑in scale or an injection volume indicator. Follow the manufacturer's instructions or your prescriber’s guidance on how many units to pull.

Important reminders

1. Always check the label – Some Norditropin pens come in 1 mg/10 mL vials, others in 0.2 mg/2 mL vials. The volume per milligram can vary.
2. Ask your healthcare provider – If you’re unsure how to dose, your doctor or pharmacist can confirm the correct volume for each pen.
3. Keep a dosing log – Write down which pen you used, the volume drawn, and the date/time of each injection. This helps avoid accidental overdosing.

Bottom line:
Take 0.2 mg from the orange pen (the same dose you take from the green pen). Because the orange pen is more concentrated, you’ll draw a smaller liquid volume (roughly 0.02 mL if the pen’s concentration is 10 mg/mL). Always double‑check the concentration on the vial or your prescription label and follow your prescriber’s instructions.
