How to Take Treatment


GLEEVEC® (imatinib mesylate) tablets is available as 100-mg and 400-mg tablets. If GLEEVEC 400 mg does not stop tumor growth, your doctor may increase your dose to 800 mg (400 mg taken twice daily), assuming you are not experiencing serious side effects.


Take GLEEVEC with a meal and a large glass of water. If you have trouble swallowing the tablets, place them in a glass of water or apple juice, stir well, and take immediately.


Talk to your oncologist and/or health care professional about any side effects you are experiencing while taking GLEEVEC. It's important to continue taking GLEEVEC for as long as your doctor prescribes it.
