Somatropin is used to treat growth failure in children and adults who lack natural growth hormone, and in those with chronic kidney failure, Noonan syndrome, Turner syndrome, Prader-Willi syndrome, short stature at birth with no catch-up growth, and other causes. Somatropin is also used to prevent severe weight loss in people with AIDS, or to treat short bowel syndrome. Somatropin may also be used for purposes not listed in this medication guide.
Norditropin is a recombinant human growth hormone used to treat people who have a growth hormone deficiency by communicating to the body to grow. Growth hormones are produced in the pituitary gland and work together with insulin like growth factor produced from the liver to send the growth messages to the body.
