Increlex is a prescription medication used to treat children with severe primary IGF-1 deficiency (IGFD) or growth failure. IGFD is a condition characterized by a lack or deficiency of Insulin-like Growth Factor-1 (IGF-1) in the body, which is crucial for stimulating growth in bones and other tissues. Increlex is a synthetic form of IGF-1, designed to mimic the action of natural IGF-1, thereby promoting growth and development in affected children. It is administered through subcutaneous injections and is typically prescribed when standard growth hormone treatments have not been effective. As with any medication, the use of Increlex should be closely monitored by a healthcare provider to manage potential side effects and ensure the best outcomes for growth and development.
