What is Trelstar?

Trelstar is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Allergan, Inc. It is a gonadotropin-releasing hormone (GnRH) agonist used for the palliative treatment of advanced prostate cancer. Trelstar is not recommended for use in pediatric patients.

What doses of Trelstar are available?

Trelstar is available as an injectable suspension, in the following doses: 3.75 mg, 11.25 mg, and 22.5 mg.

Trelstar is supplied in a Mixject single-dose delivery system and is given as an intramuscular injection in either buttock. The dosage strength is selected based on the required dosing schedule as the different strengths have different release characteristics.

Always speak with a healthcare professional for medical advice about any changes to your dose so they can monitor and evaluate your condition.

Trelstar active ingredients

Trelstar contains triptorelin pamoate, a gonadotropin-releasing hormone (GnRH) analog as the active ingredient. Testosterone and other male hormones (androgens) promote prostate cancer growth. GnRH agonists, also known as luteinizing hormone-releasing hormone agonists, block signals from the brain that tell the testicles to produce testosterone. Testosterone levels will go up initially during treatment before reducing to low levels.

Trelstar side effects

The most common side effects of Trelstar in clinical trials include:

  • Redness and swelling around the injection site
  • Hot flashes
  • Decreased sexual interest
  • Erectile dysfunction
  • Testicular atrophy
  • Breast tenderness/swelling
  • Dizziness and headache
  • Edema in the legs, and leg pain
  • Worsening of signs and symptoms of prostate cancer or onset of new symptoms

In rare instances, Trelstar can cause more serious side effects. These can include:

  • Anaphylactic shock, hypersensitivity, and angioedema
  • Transient increase in serum testosterone levels within the first few weeks of treatment. This may worsen prostate cancer and lead to spinal cord compression and urinary tract obstruction
  • Hyperglycemia (high blood sugar) and an increased risk of developing diabetes – monitor blood glucose levels
  • Increased risk of myocardial infarction, sudden cardiac death, and stroke. Chest pain or pressure, spreading to your jaw or shoulder, sudden numbness or weakness, slurred speech
  • Pituitary apoplexy
  • Bone pain, numbness, tingling, weakness of the arms or legs, blood in your urine, painful or difficult urination

Your doctor will assess the benefits of using Trelstar against your risk of side effects. Patients are encouraged to report negative side effects or adverse reactions to Trelstar to the FDA. Visit, or call 1-800-FDA-1088.
