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:

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.
