What Is Genotropin Used For?

Genotropin can treat children with growth failure due to growth hormone deficiency, Turner syndrome, Prader-Willi syndrome, or being born small for gestational age without catch-up growth. It is also approved for selected children with idiopathic short stature. Adults with confirmed growth hormone deficiency may receive it as hormone replacement.

How Does Genotropin Work?

Somatropin acts like the growth hormone made by the body. It promotes growth in eligible children and helps regulate body composition and metabolism. A specialist evaluates the cause of short stature or hormone deficiency before prescribing it.

How Is Genotropin Given?

Genotropin is injected under the skin, with the weekly dose divided into six or seven injections. The prescribed amount depends on the condition and the patient's response. Patients or caregivers receive training on preparing the product, using the injection device, and changing injection sites.

What Are the Risks of Genotropin?

Side effects can include headache, swelling, joint discomfort, or injection site changes. Treatment can affect blood sugar and thyroid function, so follow-up assessments are needed. Children with Prader-Willi syndrome require careful evaluation for breathing problems, and Genotropin must not be used in certain high-risk situations.
