What is Mylotarg?
Mylotarg is a monoclonal antibody linked to a chemotherapy drug. Monoclonal antibodies are made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
Mylotarg is used to treat a certain type of acute myeloid leukemia, and is sometimes given when this condition has come back or has not responded after prior chemotherapy.
Mylotarg may also be used for purposes not listed in this medication guide.
This medicine may cause serious or life-threatening liver problems, including veno-occlusive disease (blocked blood vessels in the liver that can lead to liver damage).
Mylotarg can also weaken (suppress) your immune system, and you may get an infection or bleed more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, flu symptoms, unusual tiredness, mouth sores, pale skin, cough, trouble breathing).
Avoid getting pregnant while receiving Mylotarg and for at least 6 months after your last dose.

an electrolyte imbalance (such as low levels of potassium or magnesium in your blood).
You may need to have a negative pregnancy test before starting this treatment.
Mylotarg can harm an unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine, whether you are a man or a woman. Men should use condoms. This medicine use by either parent may cause birth defects.
If you are a woman, keep using birth control for at least 6 months after your last dose of Mylotarg. If you are a man, keep using condoms for at least 3 months after your last dose. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using this medicine.
This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because Mylotarg may harm the baby if a pregnancy does occur.
It is not known whether Mylotarg passes into breast milk or if it could harm a nursing baby. Do not breast-feed while using this medicine and for at least 1 month after your last dose.
How is gemtuzumab ozogamicin given?
Mylotarg is injected into a vein through an IV. A healthcare provider will give you this injection. This medicine is sometimes given in combination with other cancer medicines.
You will be given other medications to help prevent serious side effects or an infusion reaction. Start and keep taking these medications exactly as your doctor has prescribed.
Mylotarg must be given slowly, and the infusion can take at least 2 hours to complete.
You will be watched closely for at least 1 hour after receiving this medicine, to make sure you do not have an infusion reaction.
Mylotarg is given in a treatment cycle, and you will receive it only on certain days of each cycle. Your doctor will determine how long to treat you with this medicine.
Mylotarg may cause serious or life-threatening liver problems, including veno-occlusive disease (blocked blood vessels in the liver that can lead to liver damage).
You will need frequent medical tests to be sure this medicine is not causing harmful effects. Your cancer treatments may be delayed based on the results of these tests.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for your Mylotarg injection.
What happens if I overdose?
