On Days 1-7 and 15-21 of each cycle, you will take temozolomide by mouth 1 time each day. You will start to take a lower dose of temozolomide for the first 2 cycles, then take a higher dose for Cycles 3 and beyond if you tolerate the treatment. It should be taken at least 2 hours before and 2 hours after eating with 1 cup (about 8 oz.) of water.
