Naxitamab-gqgk injection is used in combination with another medication in adults and children 1 year of age and older to treat neuroblastoma (a cancer that begins in nerve cells) in the bone or bone marrow that has returned or that did not respond to a previous treatment, but who have responded to other treatments. Naxitamab-gqgk injection is in a class of medications called monoclonal antibodies. It works by killing cancer cells.

Naxitamab-gqgk comes as a solution (liquid) to be injected intravenously (into a vein) over 30 to 60 minutes by a doctor or nurse in a medical facility or infusion center. It is usually given on days 1, 3, and 5 of a 28 day treatment cycle and it may be repeated based on your response. After the initial treatment, your doctor may prescribe additional treatment cycles every 8 weeks.

Your doctor will probably treat you with other medications before and during each dose to help prevent certain side effects. Your doctor may need to temporarily or permanently stop your treatment or decrease your dose of naxitamab-gqgk during your treatment. This depends on how well the medication works for you and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with naxitamab-gqgk.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
