Questions and Answers

Questions and Answers
Question Answer
How long is the use period of my pen? The pen has a use period of 2 year starting from the first use by the patient.
How can I tell how much GENOTROPIN is left in my pen? The indicative scale along the side of the cartridge window is a guide. The number that aligns with the front edge of the rubber stopper shows you how many milligrams are left in the cartridge. If your cartridge is nearly empty you can also dial the injection button until it can’t go any further; the dose display will then show the maximum dose that can be delivered. When the cartridge is empty, the injection button will not turn any further.
If the display doesn’t work, can my pen still be used? Yes, but it is not recommended. When the display or the battery doesn’t function any more, it is still possible to set the dose of your pen by counting the clicks (one click = ‘0.1’mg). Your pen can still be used while waiting for a new one. Contact your Healthcare provider.
What happens if I dial the injection button beyond the maximum dose (‘2.0’ mg)? Some liquid may appear from the needle tip, and the numbers may disappear from the dose display. This is normal and will not affect your injection. To correct this, turn the injection button in the direction of the arrow until numbers reappear on the dose display. Then dial back to your correct dose.

Instructions for Use

GENOTROPIN Mixer
(JEEN-o-tro-pin MIX-er) Growth Hormone Delivery Device for Mixing Genotropin® Lyophilized powder (somatropin [rDNA] for injection)

Important Note

Please read these instructions completely before using GENOTROPIN MIXER. If there is anything you do not understand or cannot do, call the Pfizer Bridge Program’s toll-free number at 1-800-645-1280.

The GENOTROPIN MIXER is a device used to mix growth hormone that is provided in a 2-chamber cartridge of GENOTROPIN.

For each injection you will need:

  • GENOTROPIN MIXER
  • A pressure-release needle (also called dental needle) (not included).
  • One cartridge of GENOTROPIN® Lyophilized Powder (somatropin [rDNA origin] for injection), which contains growth hormone powder in one chamber and the liquid in the other (not included).
  • Alcohol swab (not included).
  • Insulin syringe for injection (not included).
  • Proper disposal container (not included).

The diagram below identifies the different components of the GENOTROPIN MIXER. (See Figure A)

FIGURE A

Components of the GENOTROPIN MIXER - Illustration

Storage instructions for your GENOTROPIN MIXER

  • Store your GENOTROPIN MIXER (with cartridge) in the refrigerator [36°F to 46°F (2°C to 8°C)]. Always remove the needle before storing.

Using your GENOTROPIN MIXER

Step 1. Before you begin

  • First, wash and dry your hands.
  • Completely unscrew the dark green plunger rod from the light green holder of the GENOTROPIN MIXER.
  • Remove the two-chamber cartridge of GENOTROPIN from its package.

Step 2. Mixing GENOTROPIN

Insert the cartridge into the GENOTROPIN MIXER with the metallic/rubber tip of the cartridge facing into the open end of the holder. The metallic/rubber tip of the cartridge should be visible sticking out from the opening at the front of the holder.

  • Screw the plunger rod back into the holder. When the two halves are completely screwed together, the growth hormone and the diluent are automatically mixed. (See Figure B)

CAUTION: Look in the window of the GENOTROPIN MIXER to make sure the growth hormone is completely dissolved. If it is not, gently tip the GENOTROPIN MIXER from side to side until the liquid is clear. DO NOT SHAKE. The solution should be inspected visually for particulate matter and discoloration prior to administration. If the solution is still cloudy, do not inject it. Remove the cartridge and return it to your supplier. Repeat the procedure using a new cartridge.

FIGURE B

Screw the plunger rod back into the holder - Illustration

Step 3. Releasing Pressure

  • Disinfect the metallic/rubber tip of the cartridge by wiping it with an alcohol swab.
  • Remove the protective cap from the pressure-release needle. Do not touch the exposed needle. With the metallic/rubber tip of the cartridge pointing upwards, pierce the rubber tip with the needle. This will release the excess pressure in the cartridge. Be sure the cartridge is vertical when pierced, to avoid spilling the growth hormone. (This step is only performed the first time you use a new cartridge.) (See Figure C)
  • Remove the pressure-release needle from the cartridge and discard the needle in a proper disposal container.

FIGURE C

Releasing Pressure - Illustration

Step 4. Injecting GENOTROPIN

  • Disinfect the metallic/rubber tip of the cartridge by wiping it with an alcohol swab. This must be done each time before the solution is taken from the cartridge.
  • Take out an insulin syringe and remove its needle guard. Hold the GENOTROPIN MIXER upside down so that the metallic/rubber tip is pointing downwards.
  • Insert the needle of the syringe through the rubber tip of the cartridge contained in the GENOTROPIN MIXER, making sure that the needle tip always stays below the fluid level. This will minimize air from entering your syringe.
  • Holding the side of the syringe body and the end of the syringe plunger rod, pull the plunger of the syringe back slowly to draw out your prescribed dose of growth hormone.
  • Still holding the GENOTROPIN MIXER and syringe with its needle pointing upwards, gently tap the side of the syringe to move any air bubbles to the top of the syringe. Then push the syringe’s plunger gently to force the air bubbles out of the syringe. Remove the syringe. It is now ready for your injection. (See Figure D)
  • Disinfect the area to be injected as directed by your healthcare provider. Pinch the skin firmly between your thumb and forefinger. Hold the syringe close to the needle—like a dart—and push it into the skin at a 45° to 90° angle with a quick, firm action.
  • Gently and smoothly inject the growth hormone until the syringe is empty. Withdraw the needle quickly, by pulling it straight out, and apply pressure over the injection site with a dry gauze pad.
  • Discard the needle in a proper disposal container.
  • The site of the injection should be changed each day.
