You will be receiving hormone suppression treatment with monthly injections of an LH-RH analog such as Lupron or Zoladex and an antiandrogen such as Eulexin or Casodex as part of your standard care for prostate cancer. About 3 months before your next "off-treatment" period, you will start 1 Exisulind pill 250 mg (2 x 125mg capsules) by mouth twice a day. It is necessary for you to start the Exisulind treatment 3 months prior to your next "off-treatment" period so that the medication can build up in your system enough to be effective.
