Ngenla 24 mg (Somapacitan) Pen

Ngenla 24 mg is a prescription, long-acting Human Growth Hormone (HGH) containing the active ingredient Somapacitan. Manufactured by Pfizer, Ngenla represents a modern approach to growth hormone therapy, as it is designed to be administered only once per week. It is approved for the treatment of pediatric patients with growth failure due to Growth Hormone Deficiency (GHD).

Product Overview: Ngenla 24 mg (Somapacitan)

Ngenla (Somapacitan) is a next-generation biologic medication that offers an alternative to traditional, daily HGH injections. Its primary, approved use is for the treatment of children (typically 3 years and older) who are not growing properly because their bodies do not produce enough growth hormone.

The main advantage of Ngenla 24 mg is its convenience. By requiring only one injection per week instead of seven, it reduces the treatment burden on patients and their families, which can improve adherence to therapy.

The Ngenla pen is a multi-dose, pre-filled injector designed for simple and accurate subcutaneous dosing. The 24 mg strength is a lower-dose pen option for patients who require smaller weekly doses.

How Does Ngenla (Somapacitan) Work?

The active ingredient, Somapacitan, is a long-acting analog of human growth hormone. It is structurally similar to natural HGH (Somatropin) but has been modified to be broken down and cleared from the body much more slowly.

After a single subcutaneous injection, Somapacitan binds to a protein in the blood (albumin), which acts as a reservoir. This allows the growth hormone to be released slowly and consistently throughout the week, providing the sustained stimulation needed for growth. Like natural HGH, it works by promoting the production of Insulin-Like Growth Factor-1 (IGF-1), which drives bone and tissue growth.

Key Product Details

Dosage and Administration

Ngenla is administered as a ONCE-WEEKLY subcutaneous injection (an injection under the skin).

The dosage is highly individual and must be determined by a pediatric endocrinologist. It is based on the patient’s body weight and is adjusted as the child grows.

• The Ngenla pen is a multi-dose, “dial-a-dose” device that allows the caregiver to set the precise dose prescribed.
• Your healthcare provider will provide full training on how to properly store the pen, use it, attach needles, and rotate injection sites.

Important: This is a prescription-only medication. It is essential to follow the exact dosing schedule (e.g., the same day each week).

Frequently Asked Questions (FAQ) about Ngenla 24 mg

What is the main difference between Ngenla and Genotropin (or other daily HGH)?

The only major difference is the frequency. Genotropin (Somatropin) must be injected every day. Ngenla (Somapacitan) is a long-acting formula that is injected only once per week. This significantly reduces the total number of injections required.

How must Ngenla be stored?

Ngenla must be stored in a refrigerator (between 2°C and 8°C or 36°F and 46°F) before its first use. After the first injection, the pen can typically be stored in the refrigerator or at room temperature (check the product insert) for a specific period (e.g., 28 days). Do not freeze.

Is Somapacitan (HGH) an anabolic steroid?

No. Somapacitan is a peptide hormone (a growth hormone analog), not an anabolic-androgenic steroid (AAS). They are in different classes and work via different mechanisms.

What are the common side effects of Ngenla?

Side effects are similar to daily HGH. They can include injection site reactions (pain, redness), headaches, joint pain, and fluid retention. Your doctor will monitor for these.

Important Safety Information

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

Do not use Ngenla 24 mg if the patient:

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

Before starting Ngenla, tell the doctor about the patient’s full medical history, especially if they have:

• Diabetes (HGH can affect blood sugar levels).
• A history of cancer or tumors.
• Scoliosis (this can be worsened in children during periods of rapid growth).
