Zoladex is similar to a hormone chemical found in your body called gonadotropin releasing hormone (GnRH). This hormone is made by a gland in your brain that causes the release of several hormones, including testosterone. At first Zoladex may temporarily increase your levels of testosterone, but after a few weeks this drug will decrease them. Zoladex is used to treat advanced prostate cancer.
