How does this medication work? What will it do for me?
Triptorelin is a medication that has been designed to mimic the actions of gonadotropin releasing hormone (GnRH or luteinizing hormone releasing hormone, LHRH), the hormone released from the hypothalamus gland in the brain.
The hypothalamus uses GnRH to send messages to the pituitary gland in the brain, which then sends messages to the ovaries in women, and the testicles in men, telling these organs to produce the sex hormones estrogen (in women) and testosterone (in men).
Normally, GnRH comes from the hypothalamus in pulses, leading to the production of estrogen or testosterone. If GnRH came from the hypothalamus all of the time (rather than in "pulses"), it would have the opposite effect, and "turn off" hormone production. This is what triptorelin does.
Triptorelin is used to treat advanced prostate cancer. It reduces the amount of testosterone in the blood, which can cause the prostate cancer to grow.
When given to women, triptorelin reduces the amount of estrogen the body produces. It is used to manage and relieve chronic pain related to endometriosis because reduced levels of estrogen help to relieve the symptoms of this condition.

How should I use this medication?
Triptorelin is given as an injection into the muscle by your doctor. When used to treat advanced prostate cancer, it may be given once every 28 days or once every 3 months (depending on the dosage form used). When used to treat endometriosis, it is given once every 28 days for no longer than 6 months.
