Proper administration of temozolomide is essential for its effectiveness. Follow these steps:
- Timing: Take temozolomide at the same time each day to maintain consistent levels in your bloodstream.
- With or Without Food: It can be taken with or without food. However, it is often recommended to take it on an empty stomach, either one hour before or two hours after meals to enhance absorption.
