Mecasermin rinfabate — Uses, Dosage, Side Effects & Safety

Drug class: Recombinant human insulin-like growth factor (IGF-1) complex

Overview

Mecasermin rinfabate is a medication used to treat growth failure in children and adolescents who have severe primary insulin-like growth factor-1 (IGF-1) deficiency or who have developed neutralizing antibodies to growth hormone. It is a combination of recombinant human IGF-1 (mecasermin) and its binding protein (IGFBP-3), which helps regulate the activity and stability of IGF-1 in the body. This drug works by replacing or supplementing the IGF-1 that the body is unable to produce in sufficient amounts. IGF-1 is essential for normal growth and development, especially in bones and tissues. Mecasermin rinfabate helps promote linear growth in children who do not respond to growth hormone therapy. Key points for patients: Mecasermin rinfabate is given as a subcutaneous injection, usually twice daily. It is important to administer the medication with food or shortly after eating to reduce the risk of low blood sugar (hypoglycemia). Regular monitoring and follow-up with your healthcare provider are essential to ensure safety and effectiveness.
