WHY is this medicine prescribed?
Triptorelin injection is used to treat the symptoms associated with advanced prostate cancer. Triptorelin injection is in a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.
HOW should this medicine be used?
Triptorelin injection comes as a powder to be mixed with sterile water and injected into the muscle of either buttock by a doctor or nurse in a medical office or clinic. An injection of 3.75 mg of triptorelin is usually given every 4 weeks. An injection of 11.25 mg of triptorelin is usually given every 12 weeks. An injection of 22.5 mg of triptorelin is usually given every 24 weeks.
Triptorelin may cause an increase in certain hormones in the first few weeks after injection. Your doctor will monitor you carefully for any new or worsening symptoms during this time.
