About This Drug

Blinatumomab is used to treat cancer. It is given in the vein (IV).

Possible Side Effects

  • Bone marrow suppression. This is a decrease in the number of white blood cells, red blood cells, and platelets. This may raise your risk of infection, make you tired and weak (fatigue), and raise your risk of bleeding.
  • Fever in the setting of decreased white blood cells, which is a serious condition that can be life-threatening
  • While you are getting this drug in your vein (IV), you may have a reaction to the drug. Sometimes you may be given medication to stop or lessen these side effects. Your nurse will check you closely for these signs: fever or shaking chills, flushing, facial swelling, feeling dizzy, headache, trouble breathing, rash, itching, chest tightness, or chest pain. These reactions may happen after your infusion. If this happens, call 911 for emergency care.
