Gonapeptyl Depot

Gonapeptyl Depot is a depot injection containing the synthetic GnRH agonist triptorelin. It is supplied in a long‑acting formulation for intramuscular or subcutaneous use, marketed in the European Union. The product delivers controlled release of triptorelin to modulate pituitary hormone secretion in various hormone‑dependent conditions. It is prescribed by healthcare professionals for specific oncologic, gynecologic, pediatric and reproductive indications, and is available only with a prescription.

Gonapeptyl Depot is indicated for several hormone‑dependent disorders where suppression of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH) is desired.

- Treatment of advanced prostate cancer - Management of endometriosis symptoms - Reduction of uterine fibroid size - Control of central precocious puberty - Controlled ovarian stimulation in assisted reproductive technology

Side effects of Gonapeptyl Depot reflect its impact on the hypothalamic‑pituitary‑gonadal axis and may vary in frequency and severity.

Common: - Hot flashes or sweating - Injection‑site pain or erythema - Headache and fatigue - Decreased libido or sexual dysfunction - Menstrual irregularities in women

Serious: - Severe allergic reaction (anaphylaxis) - Significant loss of bone mineral density - Cardiovascular events such as thrombosis or hypertension - Rare pituitary apoplexy

Before initiating Gonapeptyl Depot, clinicians should evaluate patient history and monitor for conditions that could be aggravated by hormone suppression.

- Existing cardiovascular disease or risk factors - Low bone mineral density or osteoporosis - Impaired liver or kidney function - Pregnancy, planned conception, or breastfeeding - Known hypersensitivity to triptorelin or other GnRH analogues - Concurrent hormonal therapies that may interact

Gonapeptyl Depot can alter the pharmacodynamics of other agents, and some drugs may affect its efficacy.

Avoid: - Strong CYP3A4 inducers such as rifampin, which may reduce triptorelin levels - Estrogen‑containing contraceptives that can counteract hormone suppression - Anti‑androgen medications that may cause excessive hormonal suppression

Use with caution: - Anticoagulants, because hormonal changes can influence bleeding risk - Bisphosphonates or other bone‑protective agents, requiring monitoring of bone health - Systemic steroids, which may mask adrenal insufficiency symptoms
