A severe and sometimes fatal side effect called retinoic acid-acute promyelocytic leukemia (RA-APL) or APL differentiation syndrome has been reported with use of Trisenox in some patients. Contact your doctor immediately if you experience fever, shortness of breath, tightness in the chest, or weight gain.
Use of Trisenox may increase your risk of serious and even fatal irregular heartbeat (eg, QT prolongation, heart block). Your risk may be higher if you are taking medicine that may also increase your risk of irregular heartbeat or certain types of diuretics (eg, furosemide, hydrochlorothiazide), or if you have low blood potassium or magnesium levels, congestive heart failure, or a history of certain types of irregular heartbeat (QT prolongation, torsades de pointes). Tell your doctor about any other medicines or supplements you take. Contact your doctor immediately if you experience fainting or fast or irregular heartbeat.
Lab tests, including an electrocardiogram (ECG), blood electrolyte levels (eg, blood calcium, magnesium, and potassium), and blood creatinine levels, should be performed before and during use of Trisenox to monitor your progress and to check for side effects. Be sure to keep all doctor and lab appointments.
