About Trelstar®
Trelstar is a prescription drug type called a GnRH agonist; it is used for the treatment of advanced prostate cancer.
Prostate cancer is the most common cancer in men in the United States, and it is also the second leading cause of cancer death in these men.1,2 Over 2 million men now suffer from prostate cancer in the U.S.3
Options for treatment include watchful waiting, active surveillance, surgery, radiation therapy, chemotherapy, targeted therapy, and hormone therapy.1 The goal of hormone therapy is to stop the release of testosterone, which deprives the cancer of the hormone it needs to grow. As a GnRH agonist, Trelstar works to achieve this goal.
Indication
Trelstar® is indicated for the palliative treatment of advanced prostate cancer.
Important Safety Information
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 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, hyper allergic response, and allergic swelling related to Trelstar® have been reported. For more information on these and other side effects, please talk to your doctor.
