This medicine is used to treat certain types of brain tumors.
Your doctor will decide your dose based on your body size, tumor type, and whether you've had chemotherapy before. You might take it daily for a period with radiation, then in cycles of 5 days on, 23 days off.
Take the capsules whole with a glass of water on an empty stomach, at least one hour before breakfast. Do not open, crush, or chew the capsules. If a capsule breaks, avoid contact with skin, eyes, or nose, and rinse with water if contact occurs.
Do not take another dose on the same day if you vomit after taking your dose.
