Will Triptodur affect my child’s growth?

Yes, Triptodur may affect your child’s growth. Triptodur is approved to treat central precocious puberty (CPP) in children.* CPP occurs when a child begins puberty at an earlier age than is typically expected. With CPP, puberty begins before age 9 years in males† and before age 8 years in females.†

Children typically have a growth spurt (rapid increase in height) during puberty. For children with CPP, this growth spurt happens at an earlier age than usual. So, children with CPP are often taller than children of the same age. If CPP is not treated, children with this condition can also stop growing at an earlier age than usual. This could prevent them from reaching their full height as an adult.

Triptodur helps delay puberty for as long as the child receives injections of the medication.‡ By delaying puberty, Triptodur can help slow a child’s growth rate.

It’s important to note that many factors, such as nutrition and genetics, can influence a person’s height. It’s not possible to predict the exact height a child will reach as an adult.

Your child’s doctor will monitor your child’s height and weight during Triptodur treatment. They may also give your child X-rays to track the growth of their bones. These tests can help your child’s doctor understand whether your child’s growth rate is on track with what is expected for their age.

If you have questions about how Triptodur may affect your child’s growth, talk with their doctor.

* For more information about the approved uses of Triptodur, see the “Triptodur uses” section below.

Triptodur for central precocious puberty

Triptodur is FDA-approved to treat central precocious puberty (CPP) in children ages 2 years and older.

CPP explained

CPP occurs when a child begins puberty at an earlier age than what is typically expected.

Puberty is the process of transitioning from childhood into adulthood. It typically occurs between ages 9 to 14 years in males* and ages 8 to 13 years in females.* Changes that happen during puberty are caused by increased levels of certain hormones in the body. Examples of these hormones include estrogen and testosterone.

Below are a few signs of puberty in males and females. With CPP, these signs begin to appear before age 9 years in males and age 8 years in females:

MalesFemalesBoth males and females
Signs of puberty•growth of the scrotum and testicles
•changing voice		•growth of breast tissue
•first menstrual period		•growth spurt (rapid increase in height)
•growth of pubic and body hair
•body odor
•acne
•emotions that are heightened or change often

Effectiveness for central precocious puberty

Clinical trials have shown Triptodur to be effective for treating CPP. For information about how the drug performed in clinical trials, see Triptodur’s prescribing information.

If your child uses medications or products that contain alcohol, talk with their doctor. They can advise whether these products are safe for your child to use while receiving Triptodur.

Triptodur can interact with several other medications. However, it’s not known to interact with specific supplements or foods.

Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe. Drug-condition interactions can also cause certain effects. For information about these interactions, see the “Triptodur precautions” section below.

Triptodur and other medications

Below is a list of medications that can interact with Triptodur. This list does not contain all drugs that may interact with Triptodur.

Before your child receives Triptodur, talk with their doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs your child takes. Also tell them about any vitamins, herbs, and supplements your child uses. Sharing this information can help your child avoid potential interactions.

Receiving Triptodur with certain drugs that increase levels of prolactin (a type of hormone) could make Triptodur less effective. Due to this interaction, doctors typically will not prescribe Triptodur with these drugs. Examples include:

Certain other antidepressant drugs could also increase the risk of seizures as a side effect of Triptodur. Before starting Triptodur treatment, tell your child’s doctor if they take any of the antidepressants below.

Triptodur and lab tests

Triptodur reduces the level of certain hormones in the body. Examples of these hormones include:

Your child’s doctor may order blood tests to check your child’s hormone levels during Triptodur treatment. This is to make sure the drug is working to treat your child’s condition.

If Triptodur is working, your child’s hormone levels should decrease. And they should remain low for at least 6 to 12 months after your child’s last dose of the drug.

If you have questions about how Triptodur may affect any of your child’s lab test results, talk with their doctor.

Triptodur is approved to treat central precocious puberty (CPP) in children ages 2 years and older.

CPP occurs when a child begins puberty at an earlier age than is typically expected. With CPP, puberty begins before age 9 years in males* and before age 8 years in females.* Increased levels of certain hormones in the body cause changes during puberty. Examples of these hormones include estrogen and testosterone.

Triptodur belongs to a drug class called gonadotropin-releasing hormone agonists. It works by reducing the level of certain hormones in the body that typically increase during puberty. These include estrogen, testosterone, luteinizing hormone, and follicle-stimulating hormone. By lowering these hormone levels, Triptodur helps delay puberty for as long as your child receives the medication.

If you have questions about how Triptodur works, talk with your child’s doctor.

How long does it take to work?

It may take several weeks for Triptodur to start reducing the signs of puberty.

In fact, hormone levels may increase in the first 2 to 4 weeks after Triptodur treatment begins. This increase could temporarily worsen the signs of puberty.

However, hormone levels are expected to decrease over time. As they decrease, the signs of puberty should reduce. These signs should remain low for as long as the child continues to receive Triptodur injections.

* Sex and gender exist on spectrums. Use of the terms “male” and “female” in this article refers to sex assigned at birth.

Triptodur should not be used during pregnancy.

Triptodur may cause harm to a fetus. This is based on the pregnancy losses that occurred in animal studies and how Triptodur works in the body.

There haven’t been enough clinical trials of Triptodur during human pregnancy to know for certain if Triptodur is harmful. However, due to the possible risk of harm, doctors typically will not prescribe Triptodur during pregnancy.

If your child becomes pregnant while receiving Triptodur, tell their doctor right away.

Triptodur should not be used during pregnancy. If your child is sexually active and they or their partner can become pregnant, talk with your child’s doctor. They can recommend birth control options for your child during their Triptodur treatment.
