Trelstar IM Warnings
Trelstar IM Uses
Triptorelin is used to treat advanced prostate cancer in men. It is not a cure. Most types of prostate cancer need the male hormone testosterone to grow and spread. Triptorelin works by reducing the amount of testosterone that the body makes. This effect helps slow or stop the growth of cancer cells and helps relieve symptoms such as painful/difficult urination. This medication is similar to a natural substance made by the body (luteinizing hormone releasing hormone-LHRH). Talk to your doctor about the risks and benefits of treatment.

This medication may also be used to treat a certain disorder of the uterus (endometriosis). In women, triptorelin reduces the amount of estrogen that the body makes. Triptorelin may also be used to stop early puberty in children.How to use Trelstar IM
