Mecasermin is a man-made form of insulin-like growth factor-1 (IGF-1), a substance that is normally produced in the body. IGF-1 is important for the growth of bones and muscles. Mecasermin is used to treat growth failure in children whose bodies do not make enough IGF-1. Mecasermin may also be used for purposes not listed in this medication guide.
Increlex is categorized among growth-factor drugs. Increlex is more like insulin only that it is administered to instigate and fuel growth in humans. In most cases, Increlex is used in children who have problems with bone and muscle growth. However, Increlex can also be used by adults for muscle and bone health.
