Storage Instructions

Before use, keep Omnitrope cartridges and loaded pens in the refrigerator between 36°F and 46°F (2°C and 8°C). 

Once a cartridge has been loaded into the pen, it should not be removed until it is empty or 28 days have passed since its first use. The pen with the loaded cartridge should be stored in the refrigerator for a maximum of 28 days. Do not freeze Omnitrope. To protect medicine from light, keep Omnitrope cartridges in their original packaging until a cartridge is loaded into the pen. Remember to always keep Omnitrope and injection needles away from children.

After reconstitution of Omnitrope vials, the contents of the vial must be used within 3 weeks. Before use and after the first injection, the vial should be stored in the carton in a refrigerator between 36°F and 46°F.



Omnitrope (somatropin) injection is a laboratory-created human growth hormone. It is indicated to treat people with: 

  • Growth failure due to growth hormone deficiency (GHD)
  • Prader-Willi syndrome
  • Small for gestational age
  • Turner syndrome
  • Idiopathic short stature


How to Give Subcutaneous Injection

There are three places that a subcutaneous injection may be given: the abdomen, the thigh, or the back of your arm as shown here

  1. Select your injection site (the abdomen is preferred)
  2. Cleanse the area with alcohol and let dry. Do not blow on it.
  3. Take a pinch of the fatty tissue you have cleansed. The injection is given here.
  4. Hold the syringe like a pencil or a dart approximately 1 inch away from the skin.
  5. Insert the needle quickly (not hard), with one fluid motion, into the skin.
  6. Let go of the pinch of skin. Depress the plunger and inject all of the medication. Pull the needle straight out.
  7. Apply pressure to the injection site with a sterile gauze pad.
  8. Never reuse needles or syringes.
  9. Dispose of the syringe in a biohazard container such as a Sharps container – or in a sealable, unbreakable plastic container such as a laundry detergent bottle.

Please be aware that some of these instructions may vary based on your particular situation or preference.
