•
Give IM or subcut, do not use IV
•
Discontinue therapy if final height is achieved or epiphyseal fusion occurs
•
Visually inspect parenteral products for particulate matter and discoloration
•
No reconstitution needed; before use, swirl the contents of the vial with a gentle rotary motion, do not shake; the solution should be clear
•
Store unopened vials refrigerated, do not freeze, protect from light; once opened, the vial may be stored refrigerated ≤14 days
•
This product is supplied as a powder, filled in a two-chamber cartridge with the active substance in the front chamber and the diluent in the rear chamber; the product is available in a 5-mg cartridge (green tip) and a 12-mg cartridge (purple tip); the 5- and 12-mg cartridges may be used with the Genotropin Pen or the Genotropin Mixer; genotropin is also available, in various doses ranging from 0.2 mg to 2 mg, in single use, auto-mix devices called Genotropin Miniquicks
•
Cartridges:
Store cartridges refrigerated before reconstitution, do not freeze; protect from light; a reconstitution device supplied by the manufacturer is used to mix the powder and the diluent; after the powder and diluent are mixed, gently tip the cartridge upside down a few times until powder is completely dissolved;
do not shake;
this can cause denaturation of the protein; if the solution is cloudy, do not use; following reconstitution, the 5-mg cartridge contains a 5 mg/ml solution and the 12 mg cartridge contains a 12 mg/ml solution; the 5-mg and 12-mg cartridges contain overfill; the cartridges contain diluent with preservative (m-cresol) and may be stored refrigerated ≤28 days after reconstitution; do not use the 5-mg and 12-mg cartridges in patients with m-cresol hypersensitivity
•
Genotropin Minquicks:
After dispensing but before reconstitution, store at ≤77 degrees ≤3 months; a reconstitution device supplied by the manufacturer is used to mix the powder and diluent; ten different strengths are available that each deliver a fixed volume of 0.25 ml; this product contains a diluent with no preservative, refrigerate after reconstitution and use within 24 hr; use the reconstituted solution only once and discard any remaining solution
•
Before reconstitution, store refrigerated
•
Vials:
Reconstitute each 5-mg vial with 1.5–5 ml of the supplied diluent (contains m-cresol as a preservative) or bacteriostatic water for injection (contains benzoyl alcohol as a preservative); sterile water for injection may be used for patients with a hypersensitivity to m-cresol and benzoyl alcohol; direct the liquid against the glass vial wall; swirl vial with a gentle rotary motion until contents are dissolved completely; do not shake; if the solution is cloudy, do not use; small, colorless particles may be present after refrigeration, this is not unusual for solutions containing proteins; vials reconstituted with the diluent or bacteriostatic water are stable for 14 days when stored refrigerated; for vials reconstituted with sterile water, use the vial only once and discard the unused portion; if not used immediately, refrigerate and use within 24 hr; avoid freezing reconstituted solutions
•
Cartridges:
Reconstitute cartridges using
only
the supplied diluent syringe; the cartridges are designed for use only with the Humatrope injection device; once reconstituted, the cartridges are stable for up to 28 days when stored refrigerated; store the injection device without the needle attached; avoid freezing reconstituted solutions
•
Do not use reconstituted solution if it is cloudy or contains particulate matter
•
Before use, store refrigerated
•
Reconstitution of the cartridges is not required; the cartridge is intended for use only with the NordiPen injector; a prefilled, disposable pen, NordiFlex Pen injector, is also available; each cartridge size (5 mg, 10 mg, or 15 mg per 1.5-ml cartridge) has a color-coded corresponding pen, which is graduated to deliver an appropriate dose based on the solution’s concentration; NordiPen and NordiFlex Pen allow administration of a minimum 0.25-mg dose to a maximum 4.5-mg dose, depending on cartridge concentrations; follow directions provided in NordiPen injector instruction booklet
•
After a cartridge has been inserted into the NordiPen injector or once a NordiFlex pen is in use, the pen should be stored refrigerated and used within 4 wk; alternatively, the 5-mg and 10-mg cartridges may be stored in the pen at room temperature, no higher than 77 degrees, for up to 3 wk; NovoFine needles are recommended for administration; wipe the stopper of the pen cartridge with rubbing alcohol
•
Before reconstitution, store refrigerated

Reconstitute each 5-mg vial with 1–5 ml bacteriostatic water for injection (benzyl alcohol preserved) and each 10-mg vial with 1–10 ml of bacteriostatic water for injection (benzyl alcohol preserved); if using for newborns, reconstitute with sterile water for injection; direct the liquid against the glass vial wall; swirl vial with a gentle rotary motion until contents are dissolved completely; do not shake; if the solution is cloudy after reconstitution or refrigeration, do not use; small, colorless particles may be present after refrigeration, this is not unusual for solutions containing proteins
•
Solutions reconstituted with bacteriostatic water for injection are stable for 14 days refrigerated
•
Solutions reconstituted with sterile water for injection should be used immediately and only once; discard any unused portions; avoid freezing reconstituted solutions
•

•
Pen cartridge:
Two strengths are available, 10 mg and 20 mg; intended for use only with Nutropin AQ Pen; each pen and cartridge are color coded to ensure accurate placement of the 10-mg or 20-mg cartridge into the appropriate pen; do not use the 20-mg cartridge in the pen intended for the 10-mg cartridge, and vice versa; wipe septum of pen cartridge with rubbing alcohol or antiseptic solution to prevent contamination by microorganisms that may be introduced by repeated needle insertions; administer using sterile, disposable needles; follow the directions provided in the Nutropin AQ Pen Instructions for Use; the Nutropin AQ 10 pen allows administration of a minimum 0.1-mg dose to a maximum 4-mg dose, in 0.1-mg increments; the Nutropin AQ 20 pen allows administration of a minimum 0.2-mg dose to a maximum 8-mg dose, in 0.2-mg increments
