Tell your doctor immediately if the following effects occur: unusual/unexplained fever, shortness of breath/difficulty breathing, and/or weight gain. Your doctor may direct you to weigh yourself regularly and report any sudden weight gain. Your doctor may also perform certain exams or tests (e.g., lung exam, X-rays) to determine if this syndrome has developed.
Infrequently, this medication can also cause serious (rarely fatal) heart problems (e.g., AV block, torsades de pointes-type arrhythmias). Tell your doctor if you have any medical history of heart problems (e.g., fast/irregular heartbeat, heart failure), kidney problems, low levels of minerals in your blood (e.g., calcium, potassium, magnesium). Also tell your doctor if you take any medications that increase your risk for these heart problems or low levels of minerals (see also Drug Interactions section). To decrease your risk, your doctor may order a heart rhythm test (EKG) or blood tests before and during treatment.Who should not take arsenic trioxide intravenous?
This medication is given by injection into a vein by a health care professional over 1 to 2 hours, usually once daily or as directed by your doctor.

The dosage and length of treatment is based on your weight, medical condition, and response to treatment. Your doctor will order tests (e.g., EKG, blood minerals) to find the right dose for you. Your next dose may need to be rescheduled if your heartbeat or blood tests are abnormal.

Arsenic trioxide may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using arsenic trioxide, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using arsenic trioxide safely.
This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.
Wash your hands well to prevent the spread of infections. Do not have immunizations/vaccinations without the consent of your doctor, and avoid contact with people who have recently received oral polio vaccine or flu vaccine inhaled through the nose.
To lower your risk of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).
This drug should not be used during pregnancy. It may harm the unborn baby. If you become pregnant or think you may be pregnant, tell your doctor immediately. Talk with your doctor about effective forms of birth control.

Many drugs besides arsenic trioxide may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), ziprasidone, among others. Therefore, before using arsenic trioxide, report all medications you are currently using to your doctor or pharmacist.

Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (NSAIDs such as ibuprofen, naproxen, or aspirin) that may increase your risk of bleeding. Low-dose aspirin should be continued if prescribed by your doctor for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day).
