How do I know if my child has CPP?4
A good first step is to become familiar with the normal changes in children to help you better understand your own child’s development. (See Signs and Symptoms of CPP.) If you start seeing early signs of puberty in your child and you think he or she might have CPP, you should talk with your child’s physician. He or she may refer you to a pediatric endocrinologist (a doctor who specializes in hormonal problems in children). Only a physician can determine whether your child has CPP or is just in the early stages of normal puberty.Back to top
What are the signs of CPP?1,5
The signs of CPP are similar to what children experience during normal puberty—it’s the timing that’s different. Some common signs that may occur with CPP include pubic hair growth and a sudden growth spurt.
Common signs of CPP in girls also include development of breast “buds,” menstrual periods, and/or underarm hair growth. Boys with CPP may also show signs of testicle or penis enlargement. (See Signs and Symptoms of CPP.)Back to top
What causes CPP?3
With CPP, there is no known reason for your child’s early development. It is not caused by anything you do or have done in the past, and it’s not necessarily passed on from parents to children. Puberty just happens to be starting early for your child. Your child’s physician will conduct a thorough examination to determine whether there’s an underlying medical problem that might be causing signs of early puberty in your child. (See What Causes CPP?)Back to top
How is CPP diagnosed?2,5-8
Your pediatrician (or pediatric endocrinologist in you have been referred to one) will ask a number of questions to get a medical history of your family and your child. He or she will conduct a physical exam. He or she will run a series of tests, look at the results, and then make a diagnosis. (See How is CPP Diagnosed?)Back to top
What is a pediatric endocrinologist?3,6
If your child’s physician thinks your child may have CPP, you may be referred to a pediatric endocrinologist, a doctor who specializes in the treatment of hormone-related conditions in children.Back to top
What should I ask the pediatrician or pediatric endocrinologist?
Whether you suspect your child might be showing symptoms of CPP, or your child has already been diagnosed and you are considering treatment with LUPRON DEPOT-PED, you are sure to have questions for your doctor. See Talking With Your Child’s Physician for questions you can print out and bring with you to help start the conversation.Back to top
What is bone age and why is it important?2,5,6
Bone age is a measurement of how mature a child’s bones are. It’s important to know bone age because it can help a doctor know if a child has CPP.
To determine bone age, an x-ray is taken of a child’s hand and wrist. Children have growth plates in bones such as the fingers and wrists. As a child grows, these growth plates eventually disappear. To help determine if a child has CPP, a doctor will look to see how much of a difference there is between a child’s real age and how mature the child’s bones are. (See How Is CPP Diagnosed?)Back to top
What could happen if my child is not treated for CPP?3,9
This is an important question to ask your child's physician. Every child is unique—your child’s history, symptoms, and age will be different from those of other children who are diagnosed with CPP. Only a physician will be able to gauge the long-term consequences for your child if CPP is left untreated. (See Potential Complications of CPP.)Back to top
What are the treatment options for CPP?10,11
If your child has been diagnosed with CPP, effective treatment options are available. Your pediatric endocrinologist may prescribe medicine to help stop or even reverse the signs and symptoms of puberty until a more appropriate age for puberty to start up again.
The most common treatment for CPP is called a gonadotropin-releasing hormone (GnRH) agonist. Pediatric endocrinologists may prescribe a GnRH agonist in the form of an injection like LUPRON DEPOT-PED (See Treatment Options for CPP.).Back to top
How do I talk with my child about CPP?12
Knowing how to talk to your child about CPP and answer his or her questions can go a long way toward helping to make your child feel more comfortable with the condition and its treatment. Take a look at ideas on how you can talk to your child about CPP and about LUPRON DEPOT-PED therapy.Back to top
What is LUPRON DEPOT-PED used for?1,2,11
LUPRON DEPOT-PED 7.5 mg, 11.25 mg and 15 mg for 1-month and 11.25 mg and 30 mg for 3-month administration are prescribed for the treatment of children with CPP.
Doctors may diagnose children with CPP when signs of sexual maturity begin to develop in girls under the age of 8 or boys under the age of 9. Your doctor should perform tests to rule out possible causes of early puberty that would require different treatment (e.g., tumors).Back to top
What is the generic name for LUPRON DEPOT‑PED?11
LUPRON DEPOT-PED is also known as leuprolide acetate for depot suspension.Back to top
Who should not take LUPRON DEPOT-PED?11

How is LUPRON DEPOT-PED administered?11
LUPRON DEPOT-PED is injected into the muscle every 4 weeks or every 12 weeks depending on the formulation your pediatric endocrinologist determines is right for your child. The pediatric endocrinologist may switch the injection site between the upper arm, buttocks, or thigh. With multiple dosing options available, LUPRON DEPOT-PED allows for a treatment plan specific to your child’s needs. Your pediatric endocrinologist will determine the right dose for your child.Back to top
How often does my child need to go to the doctor during LUPRON DEPOT-PED therapy?11
Your child's doctor will determine how often he or she needs to see your child. The doctor may take several factors into consideration, including how your child is responding to medication, side effects, additional tests, and the injection schedule.
LUPRON DEPOT-PED is given as an injection every 4 weeks (for monthly dosing) or every 12 weeks (for 3-month dosing). It is important that you keep your child’s doctor appointments and follow the prescribed injection schedule to make sure your child has the right amount of LUPRON DEPOT‑PED in his or her body at all times. Your child’s pubertal development could begin again if injections are missed.
Your child’s initial response to LUPRON DEPOT‑PED should be monitored, as well as their continued response during treatment, as clinically needed. If your child receives a 1-month injection, response is assessed 1–2 months after the initial injection. If your child receives a 3-month injection, response is assessed 2–3 months after the initial injection and at month 6. Height and bone age should be checked every 6–12 months in children using LUPRON DEPOT‑PED.Back to top
Does LUPRON DEPOT-PED have any side effects?11
During the first weeks of treatment, signs of puberty, such as vaginal bleeding, may occur. This is a common initial effect of the drug. Notify your child’s doctor if signs/symptoms of puberty continue beyond the second month of treatment.
Some people taking Gonadotropin releasing hormones (GnRH) agonists,
like LUPRON DEPOT-PED have had new or worsened mental (psychiatric)
problems. Mental (psychiatric) problems may include emotional
symptoms such as crying, irritability, restlessness (impatience),
anger, and acting aggressive.
Some people taking GnRH agonists, like LUPRON DEPOT-PED have had
seizures. The risk of seizures may be higher in people who have a
history of seizures, epilepsy, brain or brain vessel (cerebrovsacular)
problems or tumors, are taking a medicine that has been connected to
seizures, such as buproprion or selective serotonin reuptake
inhibitors (SSRIs). Seizures have happened in people who have not had
any of these problems.
Call your child’s doctor right away if your child experiences any new or worsened mental (psychiatric) symptoms or problems or if your child has a seizure while taking LUPRON DEPOT-PED.
