  • Psychiatric adverse events or emotionallability, including crying, irritability, impatience, anger, and aggression were reported; many, but not all, patients had a history of psychiatric illness or other comorbidities with an increased risk of depression
  • Postmarketing reports of convulsions reported, including patients with or without a history of seizures,epilepsy,cerebrovasculardisorders,central nervous systemanomalies, and patients on concomitant medications associated with convulsions such asbupropionand SSRIs
• Adults
• Spinal cord compressionreported; observe patients closely for weakness and paresthesias in first few weeks of therapy; observe patients with metastatic vertebral lesions closely
• Tumor flare resulting from transient increases intestosterone, leading to bone pain,hematuria,bladder outlet obstruction, andneuropathyin prostate cancer patients reported during the first few weeks of therapy
• Closely observe patients forurinary tractobstruction and hematuria in the first few weeks of therapy
• Orchiectomyorluteinizing hormoneagonists are recommended as initial treatment forandrogendeprivation in patients with advanced androgen-sensitive prostate cancer
• Decrease inbone densityreported when the drug is used for more than 6 months; use caution if there are additional risk factors for bone loss, includingcorticosteroidtherapy or chronic alcohol use
• Worsening of endometriosis or uterine leiomyomata symptoms with therapy reported initially
• Rare cases ofpituitaryapoplexy, frequently secondary topituitary adenomareported (onset 1hr to usually less than 2 weeks): may present as sudden headache, vomiting, visual or mental status changes, andcardiovascularcollapse (rare), requiring immediate medical attention
• Worsening of glycemic control reported in men receiving GnRH agonists; monitorblood glucoseand/orglycosylated hemoglobin(HbA1c) periodically in patients receiving a GnRHagonistand manage with current practice for the treatment ofhyperglycemiaor diabetes
• Prostatecancer symptomsmay worsen during the initial treatment period
• Androgen deprivation therapy may prolong the QT/QTc interval; consider whether benefits of androgen deprivation outweigh potential risks in patients withcongenitallong QT syndrome, congestive heart failure, frequentelectrolyteabnormalities, and patients taking drugs known to prolong the QT interval; correct electrolyte abnormalities and monitorECGand electrolytes periodically
• Men receiving GnRH agonists for prostate cancer have a slightly increased risk of diabetes, heart attack,stroke, and sudden death

  • There is no evidence that pregnancy rates are affected following discontinuation
  • Animal studies (prepubertaland adult rats and monkeys) with leuprolide acetate and other GnRH analogs have shown functional recovery of fertility suppression
