What is Triptodur?

Triptodur is a man-made form of a hormone that regulates many processes in the body.

The Trelstar brand of triptorelin is used in men to treat the symptoms of prostate cancer. Trelstar treats only the symptoms of prostate cancer and does not treat the cancer itself.

The Triptodur brand of triptorelin is used to treat precocious puberty in boys and girls who are at least 2 years old.

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