Before Using This Medicine
It is essential to inform your doctor about the following:
If your child has any allergies to this medication, any of its components, or other medications, foods, or substances. Please describe the allergy and the symptoms your child experienced.
If your child is pregnant, as this medication should not be administered during pregnancy.
To ensure safe use, tell your doctor and pharmacist about:
All medications your child is taking, including prescription and over-the-counter drugs, natural products, and vitamins.
Any health problems your child has.
It is crucial to verify that it is safe to give this medication alongside your child's other medications and health conditions. Never start, stop, or change 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, which can lead to the onset or worsening of puberty symptoms, such as vaginal bleeding or spotting. If your child experiences any new symptoms or if these symptoms persist beyond 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 they are not pregnant.
This medication may temporarily affect fertility during treatment, which can 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, it is essential to use a non-hormone form of birth control, such as condoms, to prevent pregnancy while taking this medication.
If your child becomes pregnant or is already pregnant, this medication may pose a risk to the unborn baby. If your child is pregnant or becomes pregnant while taking this medication, contact the doctor immediately.
If your child is breastfeeding, inform the doctor, as they will need to discuss the 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)
- Injection site reactions
What to Do:
There is no specific antidote for leuprolide overdose. Treatment should be symptomatic and supportive. Contact a poison control center or emergency medical services immediately. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Monitoring
Baseline Monitoring
Rationale: Confirm diagnosis based on clinical signs, bone age, and hormonal evaluation (GnRH stimulation test).
Timing: Prior to initiation of therapy.
Rationale: To confirm central precocious puberty (LH peak > 5 mIU/mL after GnRH stimulation).
Timing: Prior to initiation of therapy.
Rationale: To establish baseline levels and confirm pubertal status.
Timing: Prior to initiation of therapy.
Rationale: To assess skeletal maturation and monitor progression.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline growth parameters and monitor growth velocity.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Every 3-6 months
Target: Regression or stabilization of pubertal signs.
Action Threshold: Progression of pubertal signs may indicate inadequate suppression or need for dose adjustment.
Frequency: Every 3-6 months or as clinically indicated
Target: Suppression to prepubertal levels (e.g., LH < 4 mIU/mL, Estradiol < 20 pg/mL, Testosterone < 20 ng/dL).
Action Threshold: Levels above prepubertal range indicate inadequate suppression.
Frequency: Every 6-12 months
Target: Slowing of bone age advancement.
Action Threshold: Rapid bone age advancement may indicate inadequate suppression.
Frequency: Every 3-6 months
Target: Normalization of growth velocity for chronological age.
Action Threshold: Accelerated growth velocity may indicate inadequate suppression.
Frequency: At each visit
Target: Minimal or no reaction.
Action Threshold: Severe or persistent reaction requires evaluation.
Symptom Monitoring
- Signs of continued pubertal progression (e.g., breast development, testicular enlargement, pubic hair growth, menstrual bleeding)
- Headache
- Hot flashes/flushing
- Mood changes
- Injection site pain, swelling, or redness
- Vaginal bleeding or discharge (especially in the first few weeks of treatment due to flare effect)
- Signs of allergic reaction (rash, itching, difficulty breathing)
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 fetal abnormalities based on its pharmacologic action.
Trimester-Specific Risks:
Lactation
Contraindicated during lactation. It is not known whether leuprolide is excreted in human milk. Due to the potential for serious adverse reactions in a breastfed infant, breastfeeding should be discontinued during treatment.
Pediatric Use
Lupron Depot-Ped is specifically indicated and dosed for pediatric patients with central precocious puberty. Safety and efficacy have been established in this population. Close monitoring of pubertal progression and hormone levels is crucial.
Geriatric Use
Not indicated for geriatric patients for central precocious puberty. Leuprolide formulations for other indications (e.g., prostate cancer) are used in geriatric populations.
Clinical Information
Clinical Pearls
- Ensure proper mixing of the lyophilized powder with the diluent immediately prior to intramuscular injection. Do not use if the solution appears clumpy or settled.
- Administer the injection deep intramuscularly, rotating injection sites to minimize local reactions.
- A transient 'flare' effect (temporary increase in pubertal signs, including vaginal bleeding in girls) may occur during the first few weeks of treatment. This is expected and usually resolves.
- Regular monitoring of clinical signs of puberty, bone age, and hormone levels (LH, FSH, sex steroids) is essential to ensure adequate suppression and guide treatment duration.
- Treatment is typically continued until the appropriate chronological age for the onset of puberty, or until growth plate fusion is complete, as determined by the treating endocrinologist.
- Educate patients and caregivers about the importance of adherence to the monthly injection schedule to maintain therapeutic suppression.
Alternative Therapies
- Other GnRH agonists (e.g., triptorelin, histrelin implant)
- Observation (for very mild or slowly progressing cases, or when the child is close to the normal age of puberty)
- Treatment of underlying cause if CPP is secondary to a treatable condition (e.g., tumor)
