Name of the Procedure:

Injection, triptorelin, extended-release, 3.75 mg

Common names: Triptorelin injection, LHRH injection
Medical terms: Triptorelin extended-release injection, Gonadotropin-releasing hormone agonist (GnRHa) injection

Summary

Triptorelin extended-release injection is a treatment procedure where a medication called triptorelin is administered to regulate hormone levels in the body. It is given as an injection into the muscle and slowly releases the medication over time.

Purpose

This injection is primarily used to treat hormone-sensitive conditions such as prostate cancer in men, endometriosis in women, and early puberty. The goal is to reduce the levels of certain hormones in the body to manage symptoms and control the progression of disease.

Indications

• Prostate cancer
• Endometriosis
• Central precocious puberty (early onset puberty)
• Uterine fibroids (in some cases)

Patient criteria:

• Diagnosis of prostate cancer, endometriosis, or central precocious puberty
• Patients who need hormone therapy to manage symptoms or progression of the condition

Preparation

• Fasting is generally not required.
• Inform your healthcare provider of any allergies or existing medical conditions.
• Review current medications with your provider, as some may need to be adjusted.
• Blood tests or imaging might be required to assess baseline hormone levels.

Procedure Description

1. The patient will sit or lie down in a comfortable position.
2. The injection site, typically in the buttock or thigh, will be cleaned with an antiseptic.
3. A healthcare professional will inject 3.75 mg of triptorelin into the muscle.
4. The injection is administered slowly to ensure proper distribution.
5. A small bandage may be applied to the injection site.

Tools/Equipment:

• Syringe and needle
• Antiseptic wipes
• Bandage

Anesthesia/Sedation: Generally not required, though a topical anesthetic cream may be used if necessary.

Duration

The procedure typically takes about 10-15 minutes from start to finish.

Setting

This procedure can be performed in a hospital, outpatient clinic, or physician's office.

Personnel

• Physician or trained nurse to administer the injection
• Medical assistant (optional)

Risks and Complications

Common risks:

• Pain or discomfort at the injection site
• Redness or swelling
• Nausea or headache

Rare risks:

• Allergic reactions
• Hormone flare (temporary increase in symptoms)
• Infection

Management:
Most side effects are managed with over-the-counter pain medications and observation. Allergic reactions or severe complications may require immediate medical attention.

Benefits

• Effective management of hormone-sensitive conditions
• Symptom relief usually begins within a few weeks to a month
• Can slow the progression of hormone-responsive cancers

Recovery

Post-procedure care includes monitoring the injection site for signs of infection and managing minor side effects at home. Recovery is typically quick, with most patients resuming normal activities immediately.

Expected recovery time:
Instant recovery with instructions to monitor the injection site.

Follow-up:
Regular appointments for ongoing injections and hormone level monitoring, usually every 1-3 months.

Alternatives

• Oral hormone therapy
• Surgical options (e.g., orchiectomy for prostate cancer)
• Other injectable GnRH agonists or antagonists

Pros and cons:

• Triptorelin: Convenient extended release but requires an injection.
• Oral therapy: Easy to administer daily but might have gastrointestinal side effects.
• Surgery: Permanent solution but involves risks associated with surgery.

Patient Experience

During the procedure, patients may feel a slight pinch or sting from the injection. Post-procedure, they might experience mild soreness or redness at the injection site. Pain management can include over-the-counter pain relievers like acetaminophen or ibuprofen. Patients are advised to report any severe or unusual symptoms to their healthcare provider immediately.
