Genotropin® (somatropin)
What is Genotropin?
Genotropin is a prescription growth hormone medicine. It is used to help children who do not make enough natural growth hormone grow and develop normally.
Genotropin is a man-made form of growth hormone that works like the growth hormone made naturally by the body.
What is growth hormone?
Growth hormone is made by the pituitary gland, a small gland in the brain. It helps children:
- Grow taller
- Build muscles
- Strengthen bones
- Maintain healthy energy levels
Some children do not make enough growth hormone. This is called growth hormone deficiency.
Genotropin may also be used for children with other growth conditions, including:
- Turner syndrome
- Prader-Willi syndrome
- Chronic kidney disease
- Children born small for gestational age who have not caught up in growth
Your child’s endocrinology provider will decide if Genotropin is right for your child.
