Arsenic trioxide (Intravenous route)


AR-se-nik trye-OX-ide

Brand Names:

Dosage Forms:


Intravenous route(Solution)

Some patients with acute promyelocytic leukemia (APL) treated with arsenic trioxide have experienced symptoms similar to a syndrome called the retinoic-acid-acute promyelocytic leukemia (RA-APL) or APL differentiation syndrome, characterized by fever, dyspnea, weight gain, pulmonary infiltrates and pleural or pericardial effusions, with or without leukocytosis. This syndrome can be fatal. At the first signs that could suggest the syndrome, immediately initiate high dose steroids (dexamethasone 10 mg IV twice daily). Arsenic trioxide can cause QT-interval prolongation and complete atrioventricular block. QT prolongation can lead to a torsade de pointes-type ventricular arrhythmia, which can be fatal. Prior to initiating therapy, perform a 12-lead ECG, assess serum electrolytes (potassium, calcium, and magnesium) and creatinine, and correct electrolyte abnormalities. Consider discontinuation of concomitant QT interval-prolonging drugs .



Antineoplastic Agent

Uses of This Medicine:

Arsenic trioxide injection is used to treat a type of leukemia (cancer of the blood cells) called acute promyelocytic leukemia (APL) in patients who have not responded to other medication regimens. It may also be used to treat other kinds of cancer, as determined by your doctor.

Arsenic trioxide belongs to the general group of medicines called antineoplastics. It interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by arsenic trioxide, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor.

Before you begin treatment with arsenic trioxide, you and your doctor should talk about the benefit of this medicine as well as the risks of using it.

This medicine is to be given only by or under the immediate supervision of your doctor.

Before Using This Medicine:

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of arsenic trioxide injection in children. However, safety and efficacy have not been established in children younger than 4 years of age.

Older adults

Although appropriate studies on the relationship of age to the effects of arsenic trioxide injection have not been performed in the geriatric population, geriatric-specific problems are not expected to limit the usefulness of arsenic trioxide injection in the elderly. However, elderly patients are more likely to have age-related kidney or liver problems, which may require caution in patients receiving this medicine. .
