Preparing the Pen Before the First Injection

Before the FIRST injection, you must prepare your pen as described below.

You only need to perform this step once. You do NOT need to repeat this procedure for the second injection or any subsequent injections.

Attaching the Needle

1. Remove the pen cap.
2. Take a new needle and remove the sealing film from the external needle protector.

1. Place the needle with the external needle protector onto the pen. Screw the external needle protector clockwise until it stops.

1. Remove the external needle protector and set it aside for later use.

Setting the Dose

1. Turn the dose selector until it stops. Make sure the number "80" is completely visible and centered in the dose window with the white mark aligned in the dose window slot.

1. Remove the internal needle protector and discard it.

1. Hold the pen with the needle facing upwards. Press the dose button until it stops and hold it for 5 seconds (see the figure on the next page).

1. Confirm the dose. Make sure the number "0" is completely visible and centered in the dose window, the white mark is aligned in the dose window slot, and the engraved marks on the dose selector and the pen body are aligned.

Removing the Needle

Always remove the needle immediately after using the pen.

1. Carefully insert the needle into the external needle protector that you set aside in step 4. Do not touch the needle to avoid pricking yourself.

Now your pen is ready for the first and all subsequent injections as described in the following section:

Injecting Duratil

Prepare for Injection

• Wash your hands before each injection.
• Prepare the injection site (on the thigh or abdomen) according to the instructions of your doctor, pharmacist, or caregiver.

Use a new needle for each injection because a new needle is sharp and allows for a virtually painless injection. A used needle poses a risk of being obstructed or contaminated.

Attaching the Needle

1. Remove the pen cap.
2. Take a new needle and remove the sealing film from the external needle protector.

1. Place the needle with the external needle protector onto the pen. Screw the external needle protector clockwise until it stops.

1. Remove the external needle protector and set it aside for later use.

Setting the Dose

1. Turn the dose selector until it stops. Make sure the number "80" is completely visible and centered in the dose window with the white mark aligned in the dose window slot.

1. Remove the internal needle protector and discard it.

1. Gently pinch a skin fold on the thigh or abdomen.
2. Insert the needle preferably at a 90-degree angle into the prepared injection site. Press the dose button until it stops and hold it for 5 seconds. Count slowly to 5.

1. Remove the needle from the skin.

1. Confirm administration of the dose. Make sure the number "0" is completely visible and centered in the dose window, the white mark is aligned in the dose window slot, and the engraved marks on the dose selector and the pen body are aligned.

Removing the Needle

Always remove the needle immediately after using the pen.

1. Carefully insert the needle into the external needle protector that you set aside in step 4. Do not touch the needle to avoid pricking yourself.

1. Unscrew the needle by turning the external needle protector counterclockwise and remove the needle from the pen.

1. Discard the needle with the external needle protector in a puncture-proof container that you can obtain from your pharmacy or doctor.

1. Put the pen cap back on the pen.

Storing the Pen

Do not store the pen with a needle attached. This can cause air bubbles to form in the medication cartridge. Always cover the pen with the pen cap.

Remove the pen from the refrigerator only when you are about to use it. Store the pen in the refrigerator, preferably in the door compartment. Do not store the pen near the back wall of the refrigerator or in the freezer. The medicinal product becomes unusable if it freezes.

If your pen has not been stored in the refrigerator for a long time, do not discard it. Put the pen back in the refrigerator and consult your doctor, pharmacist, or caregiver.

Disposable Pen

The pen must be discarded on the day of the last injection (see the Injection Diary). Discard the pen even if there is still medicinal product left in the cartridge.

Discard the pen according to the instructions of your doctor or pharmacist.

Put the pen cap on before discarding it. Do not throw away the pen with the needle attached.

What to Do If…

Air Bubbles in the Cartridge: you can use your pen without any problems.

While Preparing the Pen for the First Use, the Pen Does Not Expel Medicinal Product: repeat the steps described in the "Setting the Dose" section (page 5).

The Dose Button is Blocked or You Have the Impression That You Have Not Injected the Full Dose: do not administer a second injection on the same day. Continue with your regular injection the next day.
