Proper Use of Unituxin

Dinutuximab must be given slowly, so the needle will remain in place for 10 to 20 hours for 4 consecutive days for up to 5 cycles. You may also receive medicines to help prevent possible allergic reactions to the injection.

Drink extra fluids so you will pass more urine while you are using this medicine. This may help prevent kidney problems.

Precautions While Using Unituxin

Your doctor will check your progress closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to receive it. Blood tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment and for 2 months after the last dose of this medicine. If you think you have become pregnant while using the medicine, tell your doctor right away.

This medicine may cause a rare but serious type of an allergic reaction called an infusion reaction. This can be life-threatening and require immediate medical attention. Tell your doctor right away if you or your child start to have cough, trouble breathing, hives, itching, or skin rash, lightheadedness, dizziness, or fainting, tightness in the chest, or swelling of the face or lips.

Check with your doctor right away if you or your child are having burning, numbness, tingling, or painful sensations in the arms, hands, legs, or feet. These could be symptoms of a condition called peripheral neuropathy.

Tell your doctor right away if you or your child have a cloudy urine, change in the amount of urine, fainting or lightheadedness, nausea, stomach pain, or swelling of the hands, ankles, or feet after receiving this medicine. These may be symptoms of a rare but serious condition called capillary leak syndrome.

This medicine could lower your blood pressure too much and cause you to feel dizzy or lightheaded. If you faint, stop using this medicine until you have talked to your doctor. Stand or sit up slowly if you are dizzy. Low blood pressure is more likely to happen when you begin to use the medicine.

Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after treatment. Your doctor may want you or your child to have your eyes checked by an ophthalmologist (eye doctor).

Dinutuximab can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you or your child think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
  • Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
  • Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
  • Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
  • Avoid contact sports or other situations where bruising or injury could occur.

Tell your doctor right away if you or your child have black, tarry stools, blood in the urine, fever, increased or decreased urination, pinpoint red spots on the skin, stomach pain, swelling of the face, fingers, feet, or lower legs, unusual bleeding, bruising, or weakness, or yellow eyes or skin after receiving this medicine. These may be symptoms of hemolytic uremic syndrome.
