Uses For Genotropin
Somatropin 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 hormone deficiency (inability to produce enough growth hormone), chronic kidney disease, idiopathic short stature (unexplained shortness), Noonan syndrome, Turner syndrome, short stature homeobox-containing gene (SHOX) deficiency, and short stature born small for gestational age (SGA) with no catch-up growth by age 2 to 4 years of age.
This medicine is available only with your doctor's prescription.
