What is Unituxin?

Unituxin is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Unituxin is used in combination with other medicines to treat neuroblastoma (a type of brain tumor) in children.

Unituxin is usually given after other treatments or medicines have been tried without success.

Unituxin may also be used for purposes not listed in this medication guide.

Important Information

Do not use Unituxin if you are pregnant.

Call your doctor at once if you have severe or worsening pain, numbness, tingling, weakness, or burning in your hands or feet, or if you have problems with walking or daily activities.

Some side effects may occur during the injection or up to 24 hours afterward. Tell your caregiver right away if you feel dizzy or light-headed, or if you have a skin rash, chest tightness, wheezing, trouble breathing, or swelling in your face.

Before taking this medicine

You should not receive Unituxin if you are allergic to it.

To make sure Unituxin is safe for you, tell your doctor if you have:

  • any type of bacterial, fungal, or viral infection;

  • an eye disorder or vision problems;

  • bone marrow suppression;

  • low blood pressure;

  • an electrolyte imbalance (such as low levels of potassium, sodium, or calcium in your blood);

  • liver or kidney disease; or

  • problems with urination.

Do not use Unituxin if you are pregnant. It could harm the unborn baby. Use effective birth control to prevent pregnancy while you are using Unituxin and for at least 2 months after your treatment ends.

It is not known whether dinutuximab passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.

How is Unituxin given?

Unituxin is injected into a vein through an IV. A healthcare provider will give you this injection. This medicine must be given slowly and the IV infusion can take 10 to 20 hours to complete.

You may be given other medicines to help prevent certain side effects of dinutuximab.

Unituxin is given with other medicines in a 28-day treatment cycle, and you may only receive this medicine for 4 days per cycle. Your doctor will determine how long to treat you with this medicine.

You will be watched closely for at least 4 hours after receiving Unituxin, to make sure you do not have a reaction to the medicine.

Unituxin can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.

Your blood pressure, vision, kidney function, liver function, or nerve and muscle function may also need to be checked.

What happens if I miss a dose?

Because you will receive Unituxin in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Since Unituxin is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid after receiving Unituxin?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
