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 arsenic trioxide
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 arsenic trioxide as well as the risks of using it.
Arsenic trioxide is to be given only by or under the immediate supervision of your doctor.
Before using arsenic trioxide
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 arsenic trioxide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to arsenic trioxide or any other medicines. 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 receiving arsenic trioxide alone and in children receiving arsenic trioxide injection with tretinoin.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of arsenic trioxide injection in the elderly.
Interactions with medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving arsenic trioxide, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Interactions with food/tobacco/alcohol

Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other medical problems
The presence of other medical problems may affect the use of arsenic trioxide. Make sure you tell your doctor if you have any other medical problems, especially:
- Alcohol use, chronic or
- Malabsorption or
- Poor nutrition or
- Thiamine (vitamin B1) deficiency—Use with caution. May increase risk of having a brain disease called encephalopathy.
- Congestive heart failure or
- Heart block or
- Heart rhythm problems (eg, prolonged QT interval or torsade de pointes), history of or
- Hypokalemia (low potassium in the blood) or
- Hypomagnesemia (low magnesium in the blood)—Use with caution. May increase the risk for a more serious heart rhythm problem while taking arsenic trioxide.
- Kidney disease, severe or

Proper use of arsenic trioxide
A nurse or other trained health professional will give you or your child arsenic trioxide in a medical facility. It is given through a needle placed into one of your veins.
Arsenic trioxide often causes nausea and vomiting. However, it is very important that you continue to receive the medicine, even if you have an upset stomach. Ask your doctor for ways to lessen these effects.
Precautions while using arsenic trioxide
It is very important that your doctor check you or your child's progress at regular visits to make sure that arsenic trioxide is working properly. Blood and urine tests may be needed to check for unwanted effects.
You should not receive arsenic trioxide if you are pregnant. Using arsenic trioxide while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with arsenic trioxide and for 6 months after the last dose. Male patients with female partners should use an effective form of birth control during treatment with arsenic trioxide and for 3 months after the last dose. If you think you or your sexual partner have become pregnant while using the medicine, tell your doctor right away.
If you plan to have children, talk with your doctor before using arsenic trioxide. Some men using arsenic trioxide have become infertile (unable to have children).
Tell your doctor right away if you have chest pain or discomfort, chills, cough, difficulty with breathing, eye pain, fever, general feeling of illness, headache, sore throat, unusual tiredness or weakness, or weight gain while using arsenic trioxide. These may be symptoms of a serious condition called retinoic-acid-APL (RA-APL) or APL differentiation syndrome.
Arsenic trioxide can cause serious heart rhythm problems, including arrhythmias. Your doctor will monitor you during treatment to assess for heart rhythm problems. Talk to your doctor if you have concerns about this.
Arsenic trioxide may cause a brain disease called encephalopathy. It may also increase your risk for Wernicke’s encephalopathy, especially if you have vitamin B1 (thiamine) deficiency. This is more likely in patients who have been drinking alcohol for a long time, who also use a diuretic (eg, furosemide), or who have malabsorption and nutritional deficiency. Check with your doctor right away if you have blurred vision, loss of consciousness, confusion, dizziness, drowsiness, fever, hallucinations, headache, irritability, mood or mental changes, seizures, a stiff neck, unusual tiredness or weakness, or vomiting.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Using arsenic trioxide may increase your risk of getting other cancers. Talk to your doctor if you have concerns about this risk.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
