This medication is used to treat growth failure due to a lack of growth hormone. Growth hormone is normally produced in the brain by a certain gland (pituitary gland) and has various effects on development in the body. A lack of growth hormone in children results in slowed growth and short height for the child's age. Lonapegsomatropin works by providing more growth hormone, which may help the long bones (such as the arms and legs) grow longer.

Read the Instructions for Use if available from your pharmacist before you start using lonapegsomatropin and each time you get a refill. Ask your health care professional how to prepare and use this medication. If you have any questions, ask your doctor or pharmacist.
