Uses For Nutropin
Somatropin injection is a man-made version of human growth hormone. Growth hormone is naturally produced by the pituitary gland and is necessary to stimulate growth in children. Man-made growth hormone may be used in adults or children who have certain conditions that prevent normal growth. These conditions include growth failure caused by growth hormone deficiency (inability to produce enough growth hormone), chronic kidney disease, idiopathic short stature (unexplained shortness), or Turner syndrome.
Somatropin injection is also used together with a proper diet to treat short bowel syndrome (SBS), which is a condition that prevents the intestine or gut from absorbing food properly.
This medicine is available only with your doctor's prescription.
