It is very important that your doctor check your progress closely while you are receiving this medicine to make sure that the medicine is working properly. 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 at least 3 months after your last dose. If you think you have become pregnant while receiving the medicine, tell your doctor right away.

This medicine may cause an infusion reaction, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have chills, cough, dizziness or lightheadedness, headache, itching, nausea or vomiting, runny or stuffy nose, a rash or hives, trouble breathing, or sore throat while you are receiving this medicine.

Daratumumab 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 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.

Make sure any doctor who treats you knows that you are using daratumumab. This medicine may affect the results of certain medical tests including tests to determine your blood type. These effects may last up to 6 months after your last dose. Tell all of your healthcare providers that you are receiving this medicine before you receive a blood transfusion.
