Luteinizing hormone-releasing hormone agonists, used in advanced prostate cancer, can cause an initial testosterone surge and may inadequately suppress follicle-stimulating hormone, potentially promoting tumor growth. Injectable gonadotropin-releasing hormone (GnRH) antagonists avoid this surge but have drawbacks like injection-site reactions and monthly dosing. Relugolix, an oral GnRH antagonist, offers rapid testosterone suppression without flare and reduced cardiovascular risks. We report a 72-year-old man with suspected metastatic prostate cancer, presenting with severe neuritic pain and lower limb weakness. Relugolix, started before biopsy along with zoledronic acid and steroids, led to symptom relief within 24 h. This case supports Relugolix's utility in urgent hormone-sensitive metastatic prostate cancer care.
