About Omnitrope®

How does growth hormone treatment work?

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

In children, it works by increasing the amount of growth hormone, helping his or her bones to grow and muscles to develop.1 It is also indicated for adults with growth hormone disorders.

How is Omnitrope taken?

Omnitrope is taken via daily injection. There are two injection options available for Omnitrope1

  • a liquid-formulation pen 
  • a lyophilized powder

Convenient Injection Pens

  • Flexible dosing to fit your needs (5 mg and 10 mg)
  • Ready-to-use liquid cartridge eliminates the need to reconstitute
