Genotropin 5.3 mg (16 IU) Somatropin Pen

Genotropin 5.3 mg (16 IU) is a prescription medication containing Somatropin, a recombinant Human Growth Hormone (HGH) identical to the hormone naturally produced by the body. Manufactured by Pfizer, this multi-dose pen is used to treat growth hormone deficiency (GHD) in children and adults.

Product Overview: Genotropin 5.3 mg (Somatropin)

Genotropin (Somatropin) is a high-quality biologic medication essential for growth and metabolism. It is a vital therapy for patients who cannot produce enough of their own growth hormone.

This therapy is prescribed for:

• Children: To treat growth failure due to Growth Hormone Deficiency (GHD), Turner syndrome, Prader-Willi syndrome, or being born small for gestational age (SGA).
• Adults: To treat adult-onset GHD, which can lead to symptoms like increased body fat, decreased muscle mass, low energy, and a reduced quality of life.

The 5.3 mg (16 IU) pen is a common dosage strength, designed for use with Pfizer’s multi-dose injection devices (like the GoQuick pen), which allow for precise and convenient daily dosing.

How Does Genotropin (Somatropin) Work?

The active ingredient, Somatropin, functions exactly like natural human growth hormone. It binds to growth hormone receptors on cells throughout the body, stimulating them to grow, reproduce, and regenerate.

Its primary effect is to stimulate the liver to produce Insulin-Like Growth Factor-1 (IGF-1). This combination (Somatropin + IGF-1) is responsible for the linear bone growth (height) in children and for maintaining healthy body composition, muscle mass, and metabolism in adults.

Key Product Details

Dosage and Administration

Genotropin is administered as a subcutaneous injection (an injection under the skin), typically once daily.

The dosage is highly individual and must be determined by an endocrinologist. It is calculated based on the patient’s specific condition, body weight, and response to treatment.

• The Genotropin pen is a dial-a-dose device that allows you to set the precise dose prescribed by your doctor.
• Your healthcare team will provide full training on how to properly use the pen, attach needles, and rotate injection sites (e.g., abdomen, thigh, buttock).

Important: This is a prescription-only medication. You must follow the exact dosing schedule provided by your doctor. Do not share your pen, even if the needle is changed.

Frequently Asked Questions (FAQ) about Genotropin 5.3 mg

How must Genotropin be stored?

This is critical. Genotropin must be stored in a refrigerator (between 2°C and 8°C or 36°F and 46°F) at all times. Do not freeze it. Once the pen is in use (first injection), it is typically stable for 28 days (always check the product’s specific insert) but must remain refrigerated.

Is Somatropin (HGH) an anabolic steroid?

No. Somatropin (HGH) is a peptide hormone, not an anabolic-androgenic steroid (AAS). While it does have powerful anabolic (tissue-building) properties, it is a different class of medication and works via different mechanisms.

How long does it take for Genotropin to work?

This depends on the condition. In children with growth failure, measurable changes in growth velocity can be seen within the first 6-12 months. In adults with GHD, improvements in energy, body composition, and well-being may be noticed gradually over a period of 3 to 6 months.

What are the common side effects of Somatropin?

Common side effects are often dose-dependent and can include injection site reactions (pain, redness), fluid retention (edema, or swelling), joint pain, muscle aches, and carpal tunnel syndrome.

Important Safety Information

Warning: Somatropin (HGH) is a potent hormone and is not suitable for everyone.

Do not use Genotropin 5.3 mg if you:

• Have an active cancer or tumor. (HGH can promote the growth of tumors).
• Are critically ill due to complications from open-heart surgery, abdominal surgery, or accidental trauma.
• Have severe breathing problems.

Before starting Genotropin, tell your doctor about your full medical history, especially if you have:

• Diabetes (HGH can affect blood sugar levels and may require an adjustment to your diabetes medication).
• A history of cancer or tumors.
• Scoliosis (this can be worsened in children during periods of rapid growth).
