If your child has a cancer called Neuroblastoma, the doctor may decide to use a drug called Naxitamab. When you hear a name like this, you may feel a little scared and overwhelmed. That's normal. That's why today we're going to talk about this drug, what it does to the body, and what we need to be aware of. It's very simple, so you can understand it.
What kind of medicine is Naxitamab?
Simply put, Naxitamab (brand name DANYELZA) is a drug in a special class of drugs called monoclonal antibodies . Think of it like a trained soldier that helps our own immune system. The special proteins in this drug help our own body’s defense system find and recognize cancer cells (specifically Neuroblastoma cells), attack them, and destroy them.
This is a targeted therapy that works differently than regular chemotherapy. That means it mainly targets cancer cells. But it can also be used for other things. Talk to your doctor about it.
The most important things to tell the doctor before giving him medicine
Before your child starts this treatment, it is very important to tell the doctor some things clearly. Do not hide these things, because this information is essential for the child's safety.
- High Blood Pressure: If your child has high blood pressure or is taking medication for it, be sure to tell them.
- Allergies: Tell us if you have had an allergic reaction to any other medicine, food, or dye, not just to Naxitamab.
- Pregnancy: Tell your treatment team if you (the child's mother or guardian) are pregnant, trying to become pregnant, or have any suspicion that you may be pregnant. (This advice also applies to young people taking this medicine).
- Breastfeeding: If you are breastfeeding your baby, you should also mention that.
How do you give this medicine to a child?
This is not a pill or syrup to take at home. Naxitamab is an infusion into a vein . It is given to your child by a trained medical staff in a hospital or clinic, just like a saline solution.
This treatment is sometimes given to children as young as one year old, but special precautions must be followed. Your doctor will explain this to you.
What to do if you miss a medication appointment?
There are specific days when this treatment is to be given. It is very important to come to the hospital on those days. Do not miss these appointments for any reason . If you are unable to come on the scheduled date, call your doctor or the hospital immediately and inform them.
What if I take too much medicine?
This is given in a hospital setting, so the chances of this happening are very low. However, if you think your child has somehow received too much medicine, immediately call the National Poisons Information Centre at the Colombo National Hospital , or take your child to the Emergency Treatment Unit (ETU) of the nearest hospital.
Things we should pay special attention to when using the medicine
Doctors and nurses will be monitoring your child's condition closely throughout the course of this medication, but as parents, it's important for you to be aware of these things.
- Infusion reactions: Some children may have sudden reactions when this medicine is given to them. For example, high blood pressure, difficulty breathing, or itching. To reduce this risk, your doctor may give your child other medicines (such as painkillers or allergy medicine) before giving Naxitamab. So follow your doctor's instructions exactly.
- Pregnancy and breastfeeding: This is a very important issue.
Do not become pregnant for any reason while taking this medicine and for 2 months after stopping treatment. This medicine can seriously harm an unborn baby. Also, avoid breastfeeding your baby while taking this medicine and for 2 months after stopping treatment.
- Other medications: There is not yet complete information about how other medications interact with this medicine. Therefore, it is very important to tell your doctor about all the medications you are giving your child (including vitamins, herbal remedies, and supplements) . Also, do not start any new medications without first asking your doctor.
