Generic Name: arsenic trioxide (Intravenous route)
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, high dose steroids (dexamethasone 10 mg intravenously twice daily) should be immediately initiated. 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, a 12-lead ECG should be performed and serum electrolytes (potassium, calcium, and magnesium) and creatinine should be assessed .

Uses For Trisenox
Arsenic trioxide injection belongs to the general group of medicines called antineoplastics. It 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 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 administered only by or under the immediate supervision of your doctor.
