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.

Warnings

Do not use if you are pregnant. Use effective birth control, and tell your doctor if you become pregnant during treatment.

Some people using Triptodur have had new or worsening mental problems or seizures (convulsions). Call your doctor right away if you have a seizure, or any unusual changes in mood or behavior (anger, aggression, crying, feeling restless or irritable).

Triptodur can cause a temporary increase in certain hormones, especially when you first start using Triptodur. This may cause side effects that are similar to the condition being treated.

Triptodur can increase certain hormones when you first start using Triptodur or after each new injection.
