Temozolomide will be taken by mouth once a day for 7 days (Days 1 - 7) every 14 days starting from the second treatment of liposomal cytarabine Day 14. You will take it continuously throughout Induction and Maintenance treatment with liposomal cytarabine. Your doctor may prescribe an anti-nausea medication to be taken 1 hour before taking temozolomide. Your doctor will choose the most appropriate anti-nausea medication for you at that time. You should swallow the temozolomide capsules (usually between 1 and 5) whole and quickly one after the other. You should not chew the temozolomide capsules. If vomiting occurs during the course of treatment, no re-dosing will be done before the next scheduled dose. You should take temozolomide at bedtime and fast (not eat or drink anything except water) for at least 1 hour before each dose and for 1 hour after each dose.
