It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Receiving 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 serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Check with your doctor right away if you have chest pain, chills, cough, dizziness or lightheadedness, fast heartbeat, fever, itching, nausea or vomiting, runny or stuffy nose, sore throat, or trouble breathing after receiving this medicine.

This medicine may cause serious skin reactions at or near the injection site. Tell your doctor right away if you have bruising, itching, redness, or swelling of the skin after you receive the injection. These reactions may occur more than 24 hours after receiving this medicine.

This medicine 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 receiving daratumumab and hyaluronidase-fihj combination injection. This medicine may affect the results of certain medical tests (eg, tests to determine your blood type). These effects may last up to 6 months after your last dose. Tell your doctor or other trained health professional that you are receiving this medicine before you receive a blood transfusion.
