Triptorelin

This form:

Pronounced

"trip-toe-REL-in"

Common brand names:

Trelstar

Uses

Triptorelin is used to treat advanced prostate cancer. It is not a cure. Most types of prostate cancer need the hormone testosterone to grow and spread. Triptorelin works by reducing the amount of testosterone that the body makes. This effect helps slow or stop the growth of cancer cells and helps relieve symptoms such as painful/difficult urination. This medication is similar to a natural substance made by the body (luteinizing hormone releasing hormone-LHRH). Talk to your doctor about the risks and benefits of treatment.

Other Uses

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used for a certain disorder of the uterus (endometriosis). Triptorelin may also be used to stop early puberty in children.

How to Use This Medication

This medication is given as an injection into the muscle of your buttocks by a health care professional. It is given as directed by your doctor, usually once every month (4 weeks).

Follow the dosing schedule carefully to get the most benefit from this drug. To help you remember, mark your calendar to keep track of your next dose.

During the first few weeks of treatment, your testosterone level will actually increase before it decreases. This is a normal response by your body to this drug. This effect may result in new or worsening symptoms for the first few weeks. If you have prostate cancer that has spread to the spine or that has caused urinary blockage, you may require closer monitoring by your doctor, especially when you first start treatment. Tell your doctor right away if you experience any of the following serious side effects: bone pain, numbness/tingling/weakness of the arms/legs, blood in the urine, painful/difficult urination.

Tell your doctor if your condition does not improve or if it worsens.
