Before Using This Medicine
It is essential to inform your doctor about the following:
If your child has any allergies to this medication, its components, or other substances, including foods or drugs. Please describe the allergic reaction and its symptoms.
If your child is pregnant, as this medication should not be administered during pregnancy due to potential interactions with the pregnancy or other health issues.
To ensure safe use, tell your doctor and pharmacist about:
All prescription and over-the-counter (OTC) medications your child is taking
Any natural products or vitamins your child is using
* Your child's existing health problems
It is crucial to verify that this medication can be safely given with all your child's other medications and health conditions. Do not initiate, stop, or adjust the dosage of any medication your child is taking without first consulting with your doctor.
Precautions & Cautions
This medication may interfere with certain laboratory tests, so it is crucial to notify all healthcare providers and lab personnel that your child is taking this drug.
During the initial few weeks of treatment, this medication may cause an increase in certain hormone levels in your child's body. As a result, signs of puberty, such as vaginal bleeding or spotting, may occur or worsen before improving. If your child experiences any new symptoms or if puberty signs persist after 2 months of treatment, notify the doctor.
In some cases, this medication may affect growth in children and teenagers. To monitor this potential effect, regular growth checks may be necessary. Discuss this with the doctor to determine the best course of action.
For children of childbearing age, a pregnancy test will be required before starting this medication to confirm that your child is not pregnant.
This medication may temporarily affect fertility during treatment, which could lead to difficulty conceiving. However, fertility typically returns to normal once the medication is discontinued. If you have concerns about this potential effect, consult with the doctor.
If your child is sexually active or may become sexually active:
If your child is using birth control, it is recommended to use a non-hormonal method, such as condoms, to prevent pregnancy while taking this medication.
If your child is pregnant or breastfeeding:
This medication may harm the unborn baby if taken during pregnancy. If your child becomes pregnant while taking this medication, contact the doctor immediately.
* If your child is breastfeeding, inform the doctor to discuss any potential risks to the baby and determine the best course of action.
Overdose Information
Overdose Symptoms:
- Exaggerated pharmacological effects (e.g., initial flare of pubertal signs, then profound suppression)
- Injection site reactions
What to Do:
There is no specific antidote for leuprolide overdose. Management is supportive and symptomatic. Contact a poison control center immediately (e.g., 1-800-222-1222 in the US) or seek emergency medical attention.
Drug Interactions
Monitoring
Baseline Monitoring
Rationale: To assess growth velocity and overall development.
Timing: Prior to initiation of therapy.
Rationale: To assess the degree of pubertal development.
Timing: Prior to initiation of therapy.
Rationale: To assess skeletal maturation and predict adult height.
Timing: Prior to initiation of therapy.
Rationale: To confirm central precocious puberty and monitor therapeutic response.
Timing: Prior to initiation of therapy (basal and/or GnRH stimulation test).
Rationale: To confirm central precocious puberty and monitor therapeutic response.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 3-6 months
Target: Decreased growth velocity appropriate for prepubertal state.
Action Threshold: Continued accelerated growth velocity may indicate inadequate suppression.
Frequency: Every 6-12 months
Target: Regression or stabilization of pubertal signs.
Action Threshold: Progression of pubertal signs may indicate inadequate suppression.
Frequency: Every 6-12 months
Target: Slowing of bone age advancement to approximately 1 year per chronological year.
Action Threshold: Rapid bone age advancement may indicate inadequate suppression.
Frequency: Every 3-6 months or as clinically indicated
Target: Suppression to prepubertal levels (e.g., peak LH < 4 mIU/mL after GnRH stimulation).
Action Threshold: Failure to suppress LH/FSH to prepubertal levels may require dose adjustment or re-evaluation.
Frequency: Every 3-6 months or as clinically indicated
Target: Suppression to prepubertal levels.
Action Threshold: Elevated sex steroid levels may indicate inadequate suppression.
Frequency: At each visit
Target: Minimal or no reaction.
Action Threshold: Significant pain, swelling, or sterile abscess formation.
Symptom Monitoring
- Regression or stabilization of secondary sexual characteristics (e.g., breast development, pubic hair growth, testicular enlargement)
- Cessation of menses (in girls)
- Changes in growth velocity
- Headaches
- Hot flashes
- Mood changes
- Injection site pain, redness, swelling, or induration
Special Patient Groups
Pregnancy
Contraindicated in pregnancy. Leuprolide can cause fetal harm when administered to a pregnant woman. Pregnancy must be excluded before starting therapy.
Trimester-Specific Risks:
Lactation
Not recommended during lactation. It is not known whether leuprolide is excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants, 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
This formulation (Lupron Depot-Ped) is specifically indicated and dosed for pediatric patients with Central Precocious Puberty. Safety and efficacy have been established in this population. Treatment should be initiated and monitored by a pediatric endocrinologist or a physician experienced in the management of CPP.
Geriatric Use
Not indicated for geriatric use in this specific formulation. No specific dose adjustments or considerations for geriatric patients are relevant for Lupron Depot-Ped.
Clinical Information
Clinical Pearls
- Lupron Depot-Ped is a lyophilized powder that must be reconstituted with the supplied diluent immediately prior to intramuscular injection. Ensure proper mixing to form a uniform suspension.
- The injection must be administered intramuscularly, not intravenously or subcutaneously. Rotate injection sites to minimize local reactions.
- An initial 'flare' effect (transient increase in pubertal signs, including vaginal bleeding in girls) may occur during the first few weeks of treatment. This is expected and usually resolves with continued therapy.
- Treatment duration is individualized; therapy is typically continued until the appropriate chronological age for the onset of puberty, or until the child is ready to discontinue treatment, usually around 11-12 years of age.
- Upon discontinuation of therapy, pubertal development will resume. Fertility may be impaired in some patients, though long-term data on fertility after CPP treatment are limited.
- Regular monitoring of growth, bone age, and hormonal levels is crucial to assess treatment efficacy and guide management.
Alternative Therapies
- Triptorelin (Trelstar, Triptodur)
- Histrelin (Supprelin LA)
- Nafarelin (Synarel - nasal spray, less common for CPP)
- GnRH agonist implants (e.g., histrelin implant)
