Overview

Somatropin (rDNA Origin)

Omnitrope is a recombinant human growth hormone produced via rDNA technology with a 191 amino acid sequence identical to pituitary-derived somatropin. It is indicated for the treatment of confirmed growth hormone deficiency in adults and children. IGF-1 biomarker evaluation is required prior to initiation.

Mechanism of Action

Somatropin binds dimeric growth hormone receptors on target tissue cell membranes, initiating intracellular signal transduction and subsequent transcription and translation of GH-dependent proteins including IGF-1, IGF-BP3, and acid-labile subunit. These mediators stimulate hepatic glucose output, protein synthesis, lipolysis in adipose tissue, and support skeletal and soft tissue metabolism. GH also directly stimulates chondrocyte differentiation and supports nitrogen, sodium, potassium, and phosphorus conservation.

Injection

Administered subcutaneously at bedtime to align with the body's natural nocturnal growth hormone pulse.

Benefits

GH Axis Restoration

Replaces deficient endogenous growth hormone to restore GH-IGF-1 axis signaling in patients with confirmed laboratory-verified deficiency.

Body Composition

Supports lean tissue maintenance and lipid metabolism through IGF-1-mediated protein synthesis and GH-stimulated lipolysis in adipose tissue.

Bone Metabolism

Stimulates osteoblast activity and supports bone mineral density through GH receptor activation in skeletal tissue.

Metabolic Function

Supports hepatic glucose output, nitrogen retention, and electrolyte conservation in GH-deficient patients, normalizing the metabolic disruptions associated with GH axis insufficiency.

Individual results may vary. Benefits described are based on clinical and pharmacological evidence and do not constitute a guarantee of treatment outcomes. All treatment requires evaluation and approval by a licensed provider.

Screen for Absolute Contraindications First

Do not proceed with prescribing if any of the following are present: active malignancy or history of cancer, active proliferative or severe non-proliferative diabetic retinopathy, acute critical illness (following open-heart surgery, abdominal surgery, multiple trauma, or acute respiratory failure), or known hypersensitivity to somatropin or any excipient.

🧬

Step 1 — Required Baseline Labs

All labs must be drawn and reviewed before the first prescription is written

IGF-1 Primary GH-status marker & dosing baseline. Age-adjusted interpretation required.
HbA1c + Fasting Glucose GH induces insulin resistance. Must establish metabolic baseline before starting.
TSH (Thyroid) Uncontrolled hypothyroidism blunts GH response. Must treat thyroid first.
Cortisol AM GH therapy can unmask adrenal insufficiency. Confirm HPA axis function.
CMP (Comprehensive Metabolic Panel) Liver and kidney baseline. GH affects fluid balance and hepatic metabolism.
CBC (Complete Blood Count) Baseline hematologic status before initiating anabolic therapy.
Lipid Panel GH therapy improves lipid profiles; document baseline for tracking.
Prolactin Elevated prolactin may indicate pituitary pathology requiring imaging before GH.
PSA (Men 40+) GH stimulates IGF-1 which has proliferative effects on prostate tissue.
Total & Free Testosterone GH and testosterone are synergistic. Establish hormonal baseline.
📄

Step 2 — Medical History Review

Document and evaluate all relevant history before prescribing

Cancer History Document any personal history of malignancy. Active cancer is an absolute contraindication. History of cancer requires careful risk-benefit discussion with the patient.
Contraindication
Diabetes or Prediabetes Status GH therapy decreases insulin sensitivity. Patients with active diabetes must have glucose under control. Monitor closely and adjust diabetes medications as needed.
Required
Thyroid Disease Hypothyroidism must be treated and TSH optimized (1.0–2.5 mIU/L) before starting GH. GH can also unmask subclinical hypothyroidism during therapy.
Required
Carpal Tunnel Syndrome or Joint Disease GH causes fluid retention and can worsen or trigger carpal tunnel syndrome, joint pain, and edema, especially at higher doses. Document pre-existing conditions.
Important
Sleep Apnea GH therapy can worsen sleep apnea through fluid retention and upper airway effects. Screen for symptoms; consider sleep study if indicated before starting.
Important
Intracranial Hypertension History Rare but documented side effect of GH therapy. Patients with prior IH or papilledema require ophthalmologic evaluation before and during therapy.
Important
Current Medications Note glucocorticoids (suppress GH response), insulin, oral estrogen (increases GH dose requirement), anticonvulsants, and cyclosporine. All interact with somatropin.
Required
Pregnancy or Breastfeeding Omnitrope is not recommended during pregnancy or breastfeeding. Confirm contraceptive use in women of childbearing potential.
Contraindication
📋

Step 3 — Physical Assessment & Vitals

Document baseline measurements for treatment monitoring

Weight & BMI Dosing for GH deficiency is typically weight-based at initiation (0.1–0.3 mg/day). Document baseline for titration tracking.
Required
Waist Circumference Central adiposity is a hallmark of GH deficiency. Key body composition metric for monitoring treatment response.
Required
Blood Pressure GH can cause fluid retention and transient blood pressure elevation, particularly at the start of therapy.
Required
Symptom Severity Score Document presenting symptoms: fatigue, poor recovery, decreased muscle mass, increased body fat, brain fog, reduced libido, poor sleep quality. Baseline for outcome tracking.
Important
🏫

Step 4 — Patient Education

Patient must confirm understanding of all items before prescription is issued

Injection Technique SubQ injection into abdomen, thigh, or upper arm. Rotate sites with each injection. 90-degree angle with pinched skin. Avoid same site consecutively.
Education
Dosing Schedule & Timing Inject in the evening to mimic the body's natural nocturnal GH pulse. Consistent daily timing maximizes therapy effectiveness. Do not double-dose if a dose is missed.
Education
Storage & Handling Refrigerate at 2–8°C (36–46°F). Never freeze. Protect from light. Cartridges: use within 28 days after first use. Vials: use within 3 weeks after first use. Always refrigerate at 2–8°C.
Education
Expected Side Effects Fluid retention, joint stiffness, muscle aches, and mild swelling are common at initiation and usually resolve within 4–6 weeks as the body adjusts. These are dose-dependent.
Education
Warning Signs — When to Stop & Call Stop immediately and contact your provider if you experience: severe headache or visual changes (intracranial hypertension), numbness/tingling in hands (carpal tunnel), hip or knee pain (epiphysis), or any new lumps or skin changes.
Required
Realistic Expectations & Timeline Body composition changes take 3–6 months to become visible. Energy and sleep improvements are often felt within 4–8 weeks. IGF-1 is rechecked at 4–6 weeks for dose titration.
Education
Sharps Disposal Use an FDA-cleared sharps disposal container. Do not recap needles. Do not dispose of sharps in household trash. Contact local pharmacy for sharps disposal programs.
