Uses of This Medicine:

Triptorelin is used to treat advanced prostate cancer in men. It is a hormone that is similar to the one normally released from the hypothalamus gland in the brain. When given on a regular basis to men, triptorelin decreases testosterone levels which helps treat prostate cancer.

Triptorelin is also used to treat central precocious puberty (CPP), a condition which causes early puberty in boys (before 9 years of age) and girls (before 8 years of age).

This medicine is to be given only by or under the supervision of a doctor.

Children—

Appropriate studies have not been performed on the relationship of age to the effects of triptorelin to treat advanced prostrate cancer in the pediatric population. Safety and efficacy have not been established.

Older adults—
