A - Regimen Name


LPRL Regimen



Disease Site
Genitourinary - Prostate






Regimen Category
Evidence-Informed :

Regimen is considered appropriate as part of the standard care of patients; meaningfully improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR).  Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.



Rationale and Uses
  • for cytoreduction before brachytherapy
  • in combination with radiotherapy for the treatment of high-risk localized prostate cancer
  • for palliative treatment of recurrent, progressive or metastatic prostate cancer

  • Outpatient prescription; administer in Cancer Centre or physician’s office
  • Vary injection site
  • For long-acting preparations, reconstitute with supplied diluent immediately before injection as directed (see product monograph). 
  • Do not give multiple monthly injections together to make up a q3 or q4 month dose, as the release characteristics are different

Lupron Depot® 7.5mg, 22.5mg and 30mg:

  • For Intramuscular use only. 
  • Usual sites of injection include the anterior thigh, gluteal area or deltoid.  Vary injection sites.

  • Allow product to reach room temperature before using.


  • contraindicated in patients with hypersensitivity to the drug, its components or similar nonapeptides
  • Lupron® contains benzyl alcohol and may cause local reactions.
  • Use with caution in patients with osteoporosis (or risk factors for osteoporosis), diabetes, risk factors for QT prolongation, history of depression, cardiovascular disease, metastatic vertebral lesions and/or urinary tract obstruction due to the risk of disease flare, and in patients at risk of convulsions.
I - Recommended Clinical Monitoring

Treating physicians may decide to monitor more or less frequently for individual patients but should always consider recommendations from the product monograph.

Recommended Clinical Monitoring

  • Blood glucose levels/HbA1c; baseline and periodic, especially in diabetic patients
  • EKG, Electrolytes, (including K, Ca, Mg); baseline, also regular for at risk patients
  • Liver function tests; periodic
  • PSA; baseline and periodic
  • Clinical assessment of disease flare, local reactions, thromboembolism, cardiovascular effects, osteoporosis, psychiatric effects, hot flashes and injection site reactions; at each visit
  • Grade toxicity using the current NCI-CTCAE (Common Terminology Criteria for Adverse Events) version

Suggested Clinical Monitoring

  • Renal function tests; periodic
