Arsenic trioxide should only be administered under the direction of a physician with experience treating leukaemia patients (cancer of the white blood cells).

APL differentiation syndrome, a dangerous or sometimes fatal collection of symptoms, may be brought on by arsenic trioxide. Your doctor will keep a close eye on you to see if this syndrome is developing. Weight gain is a symptom of APL differentiation syndrome, therefore during the first few weeks of your treatment, your doctor may ask you to weigh yourself every day. Call your doctor right away if you suffer any of the following symptoms: fever, weight gain, wheezing, laboured breathing, chest pain, or cough. Your doctor will recommend one or more medications to treat APL differentiation syndrome as soon as you experience its initial symptoms.

Arsenic trioxide may result in QT prolongation, which can lead to serious or fatal heart rhythm issues by causing the heart muscles to take longer to recover between beats due to an electrical disruption. Your doctor will order an electrocardiogram (ECG; test that records the electrical activity of the heart) and other tests before you start treatment with arsenic trioxide to determine whether you already have an electrical disturbance in your heart or are more likely than average to develop this condition. Throughout your arsenic trioxide therapy, your doctor will keep a careful eye on you and may request an ECG in addition to other testing. If you have QT prolongation, heart failure, an irregular heartbeat, or low levels of potassium or magnesium in your blood, let your doctor know.Additionally, let your doctor know if you’re taking any of the following drugs: amiodarone (Nexterone, Pacerone), amphotericin (Abelcet, Amphotec, Fungizone), cisapride (Propulsid), disopyramide (Norpace), diuretics (water pills), dofetilide (Tikosyn), erythromycin (E.E.S., E-Mycin, Erythro (Geodon). If you experience an irregular or rapid heartbeat or feel dizzy while taking arsenic trioxide, call your doctor right once.

Injection of arsenic trioxide may result in encephalopathy (confusion, memory problems, and other difficulties caused by abnormal brain function). Inform your doctor if you use furosemide, have malabsorption syndrome (issues absorbing food), consume high amounts of alcohol now or have ever consumed excessive amounts of alcohol (Lasix). Call your doctor right away if you have any of the following symptoms: Confusion, loss of consciousness, seizures, altered speech, issues with balance or walking, or visual changes like blurred vision, difficulty reading, or double vision. In the event that you are unable to call for help on your own, make sure your family or caretaker is aware of any potentially dangerous symptoms.

Keep all of your appointments with your physician and the lab. To monitor your body’s reaction to arsenic trioxide, your doctor will prescribe specific tests both before and after the procedure.

Discuss the dangers of taking arsenic trioxide with your doctor.
