It Takes a Team to Manage Advanced Prostate Cancer

Advanced prostate cancer may be a part of a man’s life, but he doesn’t have to let it dictate how he lives. With the help of family, friends, their doctor, and other healthcare professionals, men have a team that can provide the support and treatment they need to successfully live with the symptoms of advanced prostate cancer. For many men, their doctor has decided that Trelstar® is an important part of their game plan.

This website will explain how Trelstar® works, what men with prostate cancer can expect during therapy, and how regular treatments with Trelstar® can easily fit into their schedule.

See why now is the time to take the next step in living with advanced prostate cancer—it’s time for Trelstar®.

Did you know?

Along with family, friends, and a dedicated healthcare team, Trelstar® can help provide the support men need to take the next step in living with advanced prostate cancer.

Trelstar® is a gonadotropin releasing hormone (GnRH) agonist indicated for the palliative treatment of advanced prostate cancer.


After your first injection of Trelstar®, you might feel a temporary increase in your cancer symptoms, such as pain in your bones, nerve disorder, blood in your urine, blockage in the canals leaving your bladder, or pressure in the spinal cord that may lead to weakness or paralysis with or without fatal complications. This is because the amount of testosterone in your bloodstream actually goes up for a short period after the injection. If your symptoms increase later than the first week or two following an injection, tell your doctor. The most common side effects that patients taking Trelstar® have are actually the effect of lowering testosterone levels. The most common effect of lowering testosterone is hot flushes or hot flashes. These are like the hot flashes women have around the time of menopause. Other side effects include bone pain, impotence (sexual side effect), tissue breakdown in the testicles, headache, leg pain, and swelling in the legs. Women who are or may become pregnant and those who are allergic to this type of drug should not take Trelstar®. A severe potentially fatal form of shock, hyperallergic response, and allergic swelling related to Trelstar® have been reported. High blood sugar and a higher risk of developing diabetes, as well as a higher risk of heart attack, sudden death due to loss of heart function, and stroke have been reported in men receiving this class of drugs. Your doctor should monitor your blood sugar level and any heart disease, and manage any conditions appropriately. For more information on these and other side effects, please talk to your doctor.
