Can I drink coffee or other caffeinated drinks with Gleevec?
Caffeine is not restricted when taking Gleevec, but you should talk to your doctor about how much caffeine, if any, is safe for you to consume during your treatment. Tip: Caffeine can irritate your digestive system and worsen medication side effects such as diarrhea and fatigue. Tip: Remember that caffeine is not just in coffee; it is also contained in many teas and soft drinks.
