10 x Humatrope Lilly 72iu Classification
Humatrope Lilly 72iu is a prescription-only medicine containing somatropin, a recombinant human growth hormone (r-hGH) used for clinically diagnosed growth hormone deficiency in adults and specific paediatric growth disorders, supplied here in the 24mg (72IU) cartridge format designed for subcutaneous injection using compatible pen systems. In the UK and EU, somatropin is classified under pituitary and hypothalamic hormones (ATC H01AC01), with pharmacological actions equivalent to endogenous human growth hormone, impacting growth plates, protein synthesis, lipid metabolism, and body composition. The Humatrope range historically included 6mg, 12mg, and 24mg cartridges; however, UK medicines supply notices confirm Humatrope cartridges have been discontinued with stock exhaustion in late April 2024, and patients are typically switched to alternative licensed somatropin brands where appropriate under specialist guidance. Despite discontinuation notices, detailed prescribing frameworks, contraindications, precautions, and dosing paradigms for somatropin remain relevant for clinical decision-making and safe patient use under NHS shared-care arrangements.
Prescription-only medicine for diagnosed growth hormone deficiency and specific paediatric indications.
- Pharmacotherapeutic group: Somatropin and somatropin agonists (ATC H01AC01).
- 24mg (72IU) single-patient cartridge intended for subcutaneous delivery with rotation of injection sites.

What is Humatrope Lilly 72iu?
Humatrope Lilly 72iu is Eli Lilly’s recombinant human growth hormone, somatropin, formulated as a white lyophilised powder in a single-patient-use 24mg (72IU) cartridge for reconstitution and subcutaneous injection. The amino acid sequence is identical to endogenous pituitary GH, designed to replace or supplement deficient growth hormone to normalise metabolic processes and, in children, support linear growth. It is indicated in adults for growth hormone deficiency and in paediatric populations for conditions including inadequate endogenous GH secretion, Turner syndrome, short stature homeobox-containing gene (SHOX) deficiency, idiopathic short stature, and children born small for gestational age who fail catch-up growth, as defined in official labelling. Administration requires a compatible pen device and adherence to reconstitution and injection instructions, with dosing titrated by a specialist based on clinical response and IGF-1 targets.
- 24mg (72IU) somatropin cartridge for subcutaneous use after reconstitution.
- Bioidentical to human GH; restores GH-dependent metabolic and growth functions.
- Adult indication: replacement therapy in GH deficiency; paediatric indications per label.
- Delivered via compatible pens with specialist-directed dosing and monitoring.
Recommended Dosage for Humatrope Lilly 72iu
Dosing is individualised and prescribed by a healthcare professional, with specific regimens differing for adults and children; adult therapy typically starts low and titrates to clinical effect and IGF-1 within the age-adjusted normal range.
- Adult non-weight-based: initiate ~0.2mg/day (range 0.15–0.3mg/day), increase by 0.1–0.2mg/day every 1–2 months based on clinical response and IGF‑1; avoid excessive dosing, especially in older or obese adults.
- Adult weight-based (not recommended in obesity): start 0.006mg/kg daily, titrate to a maximum 0.0125mg/kg daily as needed.
- Paediatric dosing: total weekly dose divided into 6–7 injections, with exact mg/kg dosing per indication and specialist direction.
- Injection sites: back of upper arm, abdomen, buttock, or thigh; rotate sites to reduce lipoatrophy risk.
- Always follow specialist titration to minimise side effects such as fluid retention and to maintain IGF‑1 within target range.
How Does Humatrope Lilly 72iu Work?
Somatropin binds to growth hormone receptors and stimulates the production of insulin-like growth factor 1 (IGF‑1), mediating anabolic and growth-promoting effects across tissues. It accelerates chondrocyte proliferation at epiphyseal growth plates in children, increases protein synthesis, reduces nitrogen loss, improves lipid profiles by raising HDL and lowering total cholesterol, and shifts body composition by decreasing fat mass and increasing lean body mass. In adults with GH deficiency, long-term therapy improves bone mineral density and body composition, supporting functional capacity and metabolic health.
- Stimulates IGF‑1 and chondrocyte activity to promote linear growth in children.
- Enhances protein synthesis and nitrogen retention; improves lipid metabolism.
- Reduces adiposity and increases lean mass; improves BMD with sustained treatment.
- May induce insulin resistance; glucose tolerance can be affected, requiring monitoring.
Benefits of Taking Humatrope Lilly 72iu
When clinically indicated and supervised, somatropin replacement offers targeted benefits that address the physiological deficits of GH deficiency.
- In children: improved growth velocity, potential normalisation of adult height in select indications, and favourable body composition changes.
- In adults: reduction in fat mass, increase in lean body mass, improved bone mineral density over time, and improved metabolic parameters.
- Quality-of-life improvements may be observed in appropriately selected adults with confirmed severe GH deficiency as part of comprehensive care.
- Benefits rely on correct diagnosis, dosing titration, and regular monitoring to balance efficacy with safety.
When should you take Humatrope Lilly 72iu?
Somatropin is administered once daily by subcutaneous injection, with timing tailored by the clinician to adherence and tolerability; many regimens favour evening dosing to physiologically align with nocturnal GH secretion, though this is not mandatory in labelling. Paediatric regimens divide weekly totals into 6–7 doses to ensure steady exposure, and adults follow daily dosing schedules with gradual titration. Site rotation every injection helps reduce local reactions and lipoatrophy.
- Daily subcutaneous injection at a consistent time as advised by the prescribing specialist.
- Rotate between abdomen, thigh, buttock, or arm injection sites.
- Adherence to the prescribed schedule is essential for efficacy and safety.
When Should You Not Take Humatrope Lilly 72iu?
Somatropin has explicit contraindications and clinical scenarios where treatment must be avoided or temporarily stopped.
- Acute critical illness after open heart or abdominal surgery, multiple accidental trauma, or acute respiratory failure due to increased mortality at pharmacologic doses.
- Active malignancy; therapy should be stopped in the presence of tumour activity.
- Active proliferative or severe non-proliferative diabetic retinopathy.
- Known hypersensitivity to somatropin or excipients.
- Paediatric patients with closed epiphyses (no linear growth potential).
- Paediatric Prader–Willi syndrome with severe obesity, sleep apnoea, or severe respiratory impairment due to risk of sudden death.
- UK shared-care guidance further cautions use post-renal transplantation in seriously ill patients and advises avoidance during pregnancy unless specialist benefits outweigh risks.
What is the Mechanism of Humatrope Lilly 72iu
Mechanistically, somatropin is a 191–amino acid peptide identical to native human GH that binds the GH receptor, activating JAK2/STAT pathways and inducing hepatic and local IGF‑1, which drives cartilage growth, protein synthesis, and metabolic modulation. Pharmacodynamically, it increases IGF‑1 and IGFBP‑3, enhances lipolysis with reduced total cholesterol and increased HDL, improves nitrogen balance, and over time increases bone mineral density in GH-deficient patients. High doses can produce insulin resistance and impair glucose tolerance, underscoring the need for careful dosing and glucose monitoring.
- GH receptor activation leads to IGF‑1–mediated growth and anabolic effects.
- Alters lipid and glucose metabolism; requires monitoring for insulin resistance.
Uses of Humatrope Lilly 72iu
Humatrope’s licensed uses include adult and paediatric indications as defined by regulatory labelling.
- Adults: replacement therapy for confirmed growth hormone deficiency.
- Children: growth failure due to inadequate endogenous GH secretion, Turner syndrome, SHOX deficiency, idiopathic short stature meeting SDS criteria, and SGA children without catch‑up growth by 2–4 years.
- Treatment decisions, initiation, and continuation typically follow specialist assessment pathways (e.g., NICE criteria and NHS shared-care where applicable).
Warnings and Precautions for Humatrope Lilly 72iu
Careful patient selection, baseline assessment, and ongoing monitoring are essential.
