Drug Interaction Report

Atazanavir may significantly increase the blood levels of revumenib. High levels of revumenib can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Increased levels of revumenib may also increase the risk of developing a serious and potentially life-threatening condition called differentiation syndrome. Symptoms of differentiation syndrome include: fever, cough, shortness of breath, severe headache, confusion, dizziness or lightheadedness, rapid weight gain, swelling of the arms, legs, neck, groin, or underarm areas, or decreased urination. You should seek immediate medical attention if you develop any of these symptoms and/or symptoms of QT prolongation such as sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with revumenib. The risk and/or severity of other side effects may also increase, including nausea, vomiting, diarrhea, fever or infections. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Grapefruit juice may also increase the blood levels of revumenib which can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Increased levels of [CS1] may also increase the risk of developing a serious and potentially life-threatening condition called differentiation syndrome.
