Before Using This Medicine
It is essential to inform your doctor about the following:
Any allergies you have, including allergies to this drug, its components, or other medications, foods, or substances. Be sure to describe the symptoms you experienced.
Your gender, as this medication is not approved for use in females. If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the potential risks with your doctor, as this medication may harm an unborn baby.
Potential interactions with other medications or health conditions. Provide your doctor and pharmacist with a comprehensive list of all your medications, including prescription and over-the-counter drugs, natural products, and vitamins. Also, share any health problems you have.
Do not start, stop, or change the dose of any medication without first consulting your doctor to ensure it is safe to do so in conjunction with this medication.
Precautions & Cautions
Regular blood tests and bone density checks are crucial while taking this medication, as directed by your doctor. Additionally, be aware that this drug may interfere with certain laboratory tests, so it is vital to inform all your healthcare providers and lab personnel that you are taking this medication.
There is a risk of developing high blood sugar, including new-onset or worsening diabetes, associated with this medication. Monitor your blood sugar levels as advised by your doctor. If you smoke, consult your doctor, as this medication may also increase cholesterol levels.
Long-term use of this drug may lead to weakened bones, increasing the risk of fractures. If you experience bone pain, contact your doctor immediately. Certain products containing this medication are not approved for use in individuals aged 65 or older or in children, so discuss any concerns with your doctor.
People with bladder blockage or spinal cord compression may be at a higher risk of severe and potentially life-threatening complications. Furthermore, reducing male hormones in the body may increase the risk of abnormal heart rhythms, known as prolonged QT interval. If you have any questions or concerns, consult your doctor.
During the initial few weeks of treatment, you may experience a worsening of symptoms, known as a tumor flare reaction. In rare cases, this can lead to paralysis or even death in individuals with advanced prostate cancer. If you have urinary blockage or cancer in the spine, inform your doctor, and seek immediate medical attention if you experience difficulty urinating or moving your legs. Report any persistent or bothersome side effects, such as bone pain, numbness, tingling, blood in the urine, or urinary difficulties, to your doctor.
Males taking this medication may have a slightly increased risk of heart attack, stroke, or sudden cardiac death. Although this risk is low, seek medical help immediately if you experience chest pain, weakness on one side of the body, speech or cognitive difficulties, balance problems, facial drooping, or changes in vision.
This medication may also affect fertility, so discuss any concerns about fathering a child with your doctor.
Overdose Information
Overdose Symptoms:
- No clinical experience with overdose. Symptoms would likely be an exaggeration of known pharmacological effects.
What to Do:
There is no specific antidote. Treatment should be symptomatic and supportive. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Major Interactions
- Drugs that prolong the QT interval (e.g., Class IA antiarrhythmics, Class III antiarrhythmics, methadone, moxifloxacin, antipsychotics): Increased risk of Torsade de Pointes due to potential for QT prolongation with GnRH agonists.
Moderate Interactions
- Androgen receptor inhibitors (e.g., enzalutamide, apalutamide, darolutamide): May be used in combination, but monitor for additive adverse effects.
- Corticosteroids: May be used to manage tumor flare, but monitor for corticosteroid-related side effects.
Monitoring
Baseline Monitoring
Rationale: To establish baseline and confirm suppression to castrate levels.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor response to therapy in prostate cancer.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline bone health due to risk of bone loss with long-term GnRH agonist therapy.
Timing: Prior to initiation of therapy, especially in patients with risk factors for osteoporosis.
Rationale: To assess baseline cardiac rhythm, especially in patients with pre-existing cardiovascular conditions or risk factors for QT prolongation.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline glucose metabolism due to risk of hyperglycemia/diabetes.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline lipid profile due to potential for dyslipidemia.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 3-6 months, or as clinically indicated.
Target: < 50 ng/dL (castrate level)
Action Threshold: If testosterone levels are not suppressed to castrate levels, investigate compliance or potential resistance.
Frequency: Every 3-6 months, or as clinically indicated.
Target: Decreasing or stable, consistent with therapeutic response.
Action Threshold: Rising PSA may indicate disease progression or treatment failure.
Frequency: Every 1-2 years for long-term therapy.
Target: Maintain or minimize loss.
Action Threshold: Significant bone loss may warrant intervention (e.g., bisphosphonates, denosumab).
Frequency: Periodically, especially in patients with diabetes or risk factors.
Target: Within normal limits or controlled.
Action Threshold: Elevated levels may require lifestyle modification or antidiabetic medication.
Frequency: Periodically.
Target: Within normal limits or controlled.
Action Threshold: Dyslipidemia may require lifestyle modification or lipid-lowering agents.
Frequency: Periodically, especially in patients with cardiovascular risk factors or symptoms.
Target: Normal rhythm, no significant QT prolongation.
Action Threshold: Significant QT prolongation or new arrhythmias require cardiology consultation.

Special Patient Groups
Pregnancy
Contraindicated in pregnancy. Leuprolide can cause fetal harm when administered to a pregnant woman. It is expected to cause abortion or teratogenic effects based on its hormonal action.
Trimester-Specific Risks:
Lactation
Not recommended during breastfeeding. It is not known whether leuprolide is excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant from leuprolide, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Lupron Depot 30mg/4 Mth is not indicated for pediatric use. Different formulations (e.g., Lupron Depot-PED) are used for central precocious puberty in children, with specific dosing and monitoring.
Geriatric Use
No specific dose adjustment is required for elderly patients. However, elderly patients may be more susceptible to some adverse effects (e.g., cardiovascular events, bone loss, diabetes). Monitor closely for these effects.
Clinical Information
Clinical Pearls
- Patients should be warned about the initial 'tumor flare' phenomenon (transient worsening of symptoms like bone pain, urinary obstruction) during the first few weeks of treatment due to the initial surge in testosterone. Anti-androgens (e.g., bicalutamide) may be co-administered for the first few weeks to mitigate this effect.
- Long-term use of GnRH agonists is associated with a risk of decreased bone mineral density, increased risk of fractures, and increased risk of cardiovascular events (e.g., myocardial infarction, stroke, sudden cardiac death) and diabetes. Monitor patients for these risks.
- Ensure proper mixing and administration technique for the depot formulation to ensure sustained release and efficacy.
- Patients should be advised to report any new or worsening symptoms, especially neurological symptoms (e.g., weakness, numbness) or severe pain, which could indicate spinal cord compression or other serious complications.
- Leuprolide is a peptide and must be administered by injection (subcutaneous or intramuscular); it is not orally bioavailable.
Alternative Therapies
- Orchiectomy (surgical castration)
- Androgen receptor pathway inhibitors (e.g., enzalutamide, apalutamide, darolutamide)
- Androgen synthesis inhibitors (e.g., abiraterone acetate)
- Chemotherapy (e.g., docetaxel, cabazitaxel)
- Radium-223 dichloride (for symptomatic bone metastases)
- Immunotherapy (e.g., sipuleucel-T)
