Contra Indications
Pregnancy, lactation; hypersensitivity to GnRH, GnRH agonist analogs or product excipients; undiagnosed abnormal vaginal bleeding.
Precautions
Vary inj site periodically. May cause transient elevation of testosterone levels during the first 1-2 wk, which may lead to worsening or onset of new symptoms (e.g. bone pain, neuropathy, haematuria) in prostate cancer patients. Ureteral obstruction and spinal cord compression have been reported; closely monitor patients with urinary obstruction and/or metastatic vertebral lesion. Leuprorelin is associated with increased risk of diabetes and certain CV diseases (heart attack, sudden cardiac death, stroke) when used in men for treatment of prostate cancer. For prostate cancer, monitor response by testosterone and prostate-specific antigen (PSA) levels.
For precocious puberty in children, monitor response by GnRH stimulation test sex steroid levels 1-2 month after treatment initiation. Leuprorelin usually inhibits ovulation and stops menstruation in women, but does not incur contraception, non-hormonal contraception should be used as pregnancy is contraindicated. May cause adverse reactions associated with hypoestrogenism and loss in bone density.
Lactation: Contraindicated; not known if drug is excreted in breast milk; make decision to either discontinue nursing or discontinue drug, taking into account risk and benefits to the mother

Mechanism of Action
Leuprorelin is a gonadotropin-releasing hormone (GnRH) analogue. Following an initial stimulation of gonadotrophins, continuous admin of Leuprorelin leads to down regulation of GnRH receptors and subsequently reduces pituitary gonadotrophin secretion. Reduced gonadotrophin levels lead to inhibition of sex hormone (testosterone and oestrogen) production. Within 2-4 wk after treatment initiation, testosterone levels in male may be reduced to below castrate threshold.
