Question 1

What is Histrelin?

Accepted Answer

Histrelin belongs to a class of medications known as gonadotropin-releasing hormone (GnRH) agonists. It is a man-made version of a hormone that occurs naturally in the body.

This medication works by acting on the pituitary gland to decrease the production of specific hormones, such as testosterone and estrogen. By lowering these hormone levels, it helps regulate various hormone-sensitive processes in the body.

Question 2

What is Histrelin used for?

Accepted Answer

Histrelin is used to treat central precocious puberty and advanced prostate cancer .

Question 3

How does Histrelin work?

Accepted Answer

Mechanism of Action

Histrelin belongs to a class of medications known as gonadotropin-releasing hormone (GnRH) agonists. It works by acting on the pituitary gland to regulate the production of specific hormones in the body.

Hormone Suppression

Initially, histrelin may cause a temporary increase in hormone levels. However, with continuous delivery, the medication causes the pituitary gland to stop sending signals to the ovaries or testes. This results in a significant drop in the levels of sex hormones, including testosterone and estrogen.

Clinical Effects

In children experiencing central precocious puberty, lowering these hormone levels helps to:

Slow down the early development of sexual characteristics.

Delay the rapid bone maturation that can lead to shorter adult height.

The medication is usually administered as a subcutaneous implant, which allows for a slow and steady release of the drug into the system over a long period of time.

Question 7

What drug class is Histrelin?

Accepted Answer

Histrelin belongs to the GnRH agonist drug class.

Question 8

What is the dosage of Histrelin and how do I take it?

Accepted Answer

Administration

Histrelin is provided as a small, flexible implant that is inserted under the skin of the inner, upper arm. This procedure is performed by a healthcare professional in a medical setting using a local anesthetic to numb the area. Once inserted, the implant remains in place to release the medication slowly over time.

Treatment Schedule

The implant is designed to stay in place for 12 months. At the end of this period, the implant must be surgically removed by a healthcare provider. If continued treatment is necessary, a new implant may be inserted at the time the old one is removed, often in the opposite arm.

Care of the Insertion Site

After the procedure, your healthcare provider will provide specific instructions for wound care. General guidelines typically include:

Keeping the incision site clean and dry for a specific number of days.

Avoiding heavy lifting or strenuous exercise for a short period after insertion.

Leaving any surgical strips or bandages in place as directed by the medical professional.

Missed Appointments

Because this medication is administered as a long-term implant, it is important to keep all follow-up appointments. If you miss an appointment to have the implant replaced or removed, contact your healthcare provider as soon as possible to reschedule the procedure.

Question 9

Is Histrelin safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy Risks

Histrelin is not recommended for use during pregnancy. Evidence suggests that this medication may cause birth defects or lead to a miscarriage. Before starting treatment with a histrelin implant, healthcare providers typically perform a pregnancy test to confirm the patient is not pregnant.

If you become pregnant or suspect you might be pregnant while using histrelin, you should notify your healthcare provider immediately.

Contraception

Individuals of childbearing age should use effective contraception during treatment. Because histrelin affects hormonal balance, healthcare providers often recommend using non-hormonal birth control methods, such as:

Condoms

Diaphragms

Spermicides

Breastfeeding

It is currently unknown if histrelin passes into human breast milk or if it could affect a nursing child. Due to the lack of safety data, it is important to discuss the risks and benefits with a healthcare professional before breastfeeding while using this medication.

Question 10

What forms and strengths does Histrelin come in?

Accepted Answer

Available Forms

Histrelin is administered as a subcutaneous implant. This small, flexible device is surgically placed under the skin, usually on the inner part of the upper arm, by a healthcare professional.

Strengths and Administration

The implant is designed to provide a steady, continuous release of medication over a long period. It is available in formulations intended for specific conditions:

Advanced Prostate Cancer: A single implant provides continuous treatment for approximately 12 months.

Central Precocious Puberty: A single implant provides continuous treatment for children with early-onset puberty for approximately 12 months.

The implant must be removed or replaced by a healthcare provider at the end of the treatment period.

Question 11

What is the FDA approval status of Histrelin?

Accepted Answer

FDA Approval and Indications

Histrelin is approved by the U.S. Food and Drug Administration (FDA) for two specific clinical uses:

Advanced Prostate Cancer: It is indicated for the palliative treatment of advanced prostate cancer. In this context, it helps manage symptoms by suppressing the production of testosterone.

Central Precocious Puberty (CPP): It is approved for use in children who begin puberty at an abnormally early age (typically before age 8 for girls and age 9 for boys).

Safety Communications

The FDA has monitored safety signals regarding the use of GnRH agonists, including histrelin. In 2017, the FDA identified a potential risk of serious psychiatric events in children treated for central precocious puberty. These events may include emotional lability, irritability, and aggression. Healthcare providers are encouraged to monitor patients for new or worsening psychiatric symptoms during treatment.

Regulatory Status of Administration

Histrelin is regulated as a prescription medication and is administered as a subcutaneous implant. This delivery method is designed to provide a continuous release of the medication over a 12-month period. Because the implant requires a minor surgical procedure for both insertion and removal, it must be managed by a healthcare professional in a clinical setting.

Question 12

What should I know about Histrelin and cost?

Accepted Answer

Cost Considerations

Histrelin is administered as a long-acting subcutaneous implant. Because it requires professional medical administration, the total cost of treatment involves more than just the price of the medication itself.

Clinical Procedures: The implant must be surgically inserted and later removed by a healthcare provider. Patients may incur costs related to the office visit, the surgical procedure, and any local anesthesia used during the process.

Insurance Benefits: Coverage for histrelin often falls under a medical benefit rather than a pharmacy benefit. The out-of-pocket cost will depend on the patient's specific insurance plan, including deductibles and coinsurance requirements.

Treatment Indication: The specific formulation prescribed—whether for central precocious puberty or advanced prostate cancer—may affect how the medication is billed and covered.

Patients are encouraged to contact their insurance provider and the administering clinic to obtain a specific cost estimate before the procedure.
