IMPORTANT PREVENTION NOTIFICIATION

To help prevent infection, always wash your hands with soap and water before
preparing or using the GENOTROPIN PEN 12.

A

– Attach the Needle

 Remove the front cap from the GENOTROPIN PEN 12.
 Unscrew the metal front part and detach it from the plastic body of the pen.
 Remove the paper covering from the back of a new needle.
 Screw the needle onto the metal front part by gently turning it clockwise (to the right).

B

– Insert the Two-Chamber Cartridge of GENOTROPIN

 Use only the 12mg cartridge.
 Wipe the metal/rubber tip of the cartridge with an alcohol swab.
 Insert the cartridge into the metal front part of the pen, with the metal/rubber tip towards the needle end. Push the cartridge firmly into place.

C

– Prepare the Body of the Pen

 Press the red release button to release the black/white injection knob.
 Turn the black/white injection knob counterclockwise (to the left) as far as it will go.
 Check that the plunger rod is not visible through the window at the top of the plastic
body of the pen. Do NOT proceed if the plunger rod is visible, as the medication will
not be properly mixed. Instead, press the red release button again to draw back the plunger rod. After the rod is no longer visible through the window, proceed to the next step.

D

– Screw the GENOTROPIN PEN 12 Together

 Hold the metal front part upright.
 While holding upright, gently screw the metal front part and the plastic body back together. This mixes the diluent in the rear chamber of the cartridge with the growth hormone powder in the front chamber.
 Gently tip the assembled GENOTROPIN PEN 12 from side to side to help dissolve the powder completely. DO NOT SHAKE as that might inactivate the growth hormone.

E

– Examine Solution and Release Trapped Air

 Look through the cartridge windows in the metal front part of the pen and make sure the drug solution is clear. If you see particles or if the solution is discolored, DO NOT INJECT IT. Instead, call the toll-free number listed at the end of these instructions.
 Remove the outer needle cap and save it for later.
 Remove and discard the inner needle cap. Be careful not to touch the exposed needle.
 Remove any trapped air from the solution as follows:

a) Turn the black/white injection knob clockwise (to the right) one click. This will line up the white mark on the injection knob and the black mark on the body of the pen.

b) Hold the GENOTROPIN PEN 12 upright and gently tap the metal front part with your finger to move any air bubbles to the top.

c) Push the black/white injection knob all the way in. You will see a drop of liquid appear at the needle point. Any trapped air has now been released.

d) If no liquid squirts out, press the red release button and turn the black/white injection knob clockwise (to the right) until it clicks once. Repeat steps b) and c).

 If desired, attach the reusable needle guard over the needle—push until it snaps in place. Again, be careful not to touch the exposed needle. To avoid an accidental needle stick, grip the sides of the needle guard; never push on the end.

F

– Dial Your Prescribed Dose

Press the red release button to reset the device.
 The black/white injection knob will pop out and the dose display window will read 0.0.
 With the dose display activated, turn the black/white injection knob clockwise (to the right) until your prescribed dose is displayed.
 If you go too far, just turn the knob back the other way until the correct dose is displayed. NOTE: If you turn the black/white injection knob backwards beyond zero after a cartridge has been inserted, the pen display will show (–). Just turn the injection knob forward (clockwise) until numbers reappear on the dose display.
 The GENOTROPIN PEN 12 contains a battery for the dose display. To save the battery’s energy, the dose display is activated for two minutes and then automatically disappears. Although the display is no longer visible, the dose remains available for
delivery. NOTE: Each click of the black/white injection knob equals a two-tenth-of-a milligram dose (or 0.2 mg). One click—or 0.2mg—is the minimum possible dose per injection; 20 clicks—or 4.0 mg—is the maximum possible dose per injection. If you accidentally dial

COMMON QUESTIONS

How do I tell how much GENOTROPIN is left in the GENOTROPIN PEN 12?

Look at the dose scale imprinted along the side of the window on the metal front part of the pen. The front edge of the gray rubber plunger lines up with the number of milligrams remaining in the cartridge.

What happens when the battery runs low?

The battery in the GENOTROPIN PEN 12 should run for two years. When it begins to run low due to the end of the battery´s life, you will see a flashing symbol ( ) in the dose display.
This means the battery will last about another month. When the battery is dead, the dose display will show a steady .
A flashing”bt” means the battery is running very low for some other reason and will last for about another month.
When the battery is dead, the display will then show a steady “bt”.
