Intravenous route(Solution)

Differentiation Syndrome, Cardiac Conduction Abnormalities, and Encephalopathy including Wernicke'sPatients with acute promyelocytic leukemia (APL) treated with arsenic trioxide have experienced symptoms of differentiation syndrome, which may be life-threatening or fatal. If differentiation syndrome is suspected, immediately initiate high-dose corticosteroids and hemodynamic monitoring until resolution. Temporarily withhold arsenic trioxide.

Arsenic trioxide can cause QTc interval prolongation, complete atrioventricular block and torsade de pointes, which can be fatal. Before administering arsenic trioxide, assess the QTc interval, correct electrolyte abnormalities, and consider discontinuing drugs known to prolong QTc interval. Do not administer arsenic trioxide to patients with ventricular arrhythmia or prolonged QTc interval. Withhold arsenic trioxide until resolution and resume at reduced dose for QTc prolongation.

Serious encephalopathy, including Wernicke’s, has occurred with arsenic trioxide. If Wernicke’s encephalopathy is suspected, immediately interrupt arsenic trioxide and initiate parenteral thiamine. Monitor until symptoms resolve or improve and thiamine levels normalize .

Uses for Trisenox

Arsenic trioxide injection is used together with another medicine (eg, tretinoin) to treat newly-diagnosed low-risk acute promyelocytic leukemia (APL), a type of leukemia (cancer of the blood cells). It is also used to treat 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 injection, you and your doctor should talk about the benefits 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.

Pediatric

However, safety and efficacy have not been established in children younger than 4 years of age receiving arsenic trioxide alone and in children receiving arsenic trioxide injection with tretinoin.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of arsenic trioxide injection in the elderly.

Precautions while using Trisenox

It is very important that your doctor check you or your child's progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

You should not receive this medicine if you are pregnant. Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with this medicine and for 6 months after the last dose. Male patients with female partners should use an effective form of birth control during treatment with this medicine and for 3 months after the last dose.
