What is the most important information I should know about triptorelin?

Although triptorelin is not for use by women, this medication can cause birth defects and should not be used by a woman who is pregnant or who may become pregnant.

You should not use this medication if you are allergic to triptorelin or similar drugs such as leuprolide (Lupron, Viadur, Eligard) or goserelin (Zoladex).

What is triptorelin?

Triptorelin is a man-made form of a hormone that regulates many processes in the body. Triptorelin overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily.

Triptorelin is used to treat the symptoms of prostate cancer. Triptorelin treats only the symptoms of prostate cancer and does not treat the cancer itself. Use any other medications your doctor has prescribed to best treat your condition.

Triptorelin may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using triptorelin?

You should not use this medication if you are allergic to triptorelin or similar drugs such as leuprolide (Lupron, Viadur, Eligard) or goserelin (Zoladex).

To make sure triptorelin is safe for you, tell your doctor if you have:

  • any type of cancer that has spread to your spine;
  • a bladder obstruction or problems with urination;
  • diabetes, recent weight gain, high cholesterol (especially in men);
  • heart disease, high blood pressure, high cholesterol;
  • personal or family history of long QT syndrome;
  • a history of heart attack or stroke; or
  • if you smoke.

Although triptorelin is not for use by women, this medication can harm an unborn baby or cause birth defects. Triptorelin should not be used by a woman who is pregnant or who may become pregnant.

It is not known whether triptorelin passes into breast milk or if it could harm a nursing baby. Although triptorelin is not for use by women, this medication should not be used while breast-feeding a baby.

How should I use triptorelin?

Triptorelin is usually given once every 4, 12, or 24 weeks. Your dose schedule will depend on the strength of triptorelin you are using. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Triptorelin is injected into a muscle. You may be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes.

Triptorelin is a powder medicine that must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.

Do not shake the mixed medicine or it may foam. Prepare your dose only when you are ready to give an injection. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

After your injection, your prostate cancer symptoms may get worse for a short time because triptorelin raises your testosterone levels. These side effects should get better within 3 or 4 weeks. Call your doctor if your symptoms do not improve, or if they get worse while using triptorelin.

While using triptorelin, you may need frequent blood tests.

Each single use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

Use a disposable needle only once, then throw away in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

Store vials and prefilled syringes at room temperature away from moisture, heat, and light. Do not freeze.

What happens if I miss a dose?
