At a glance
What is it—and why does it matter?
As a GnRH analogue, ZOLADEX in a biodegradable formulation inhibits pituitary gonadotropin secretion. The contraindication includes known hypersensitivity to GnRH, GnRH agonist analogues, or formulation components of ZOLADEX. The prescribing instructions specify subcutaneous administration of the 10.8 mg goserelin implant every 12 weeks into the anterior abdominal wall below the navel line, using aseptic technique and physician supervision. The labeled indication includes palliative treatment of advanced prostate carcinoma with goserelin (ZOLADEX).
