Uses For Zorbtive

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 growth failure caused by growth hormone deficiency (inability to produce enough growth hormone).

Somatropin 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.
