You could feel extreme tiredness, agitation, confusion, hallucinations (see or hear things that are not there), trouble understanding or speaking, loss of control of your bowels or bladder, eyesight changes, numbness or lack of strength to your arms, legs, face, or body, or coma. If you start to have any of these symptoms let your doctor know right away. 
  • Protein in your urine, which can cause kidney failure.
  • 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 for 24 hours after your infusion. If this happens, call 911 for emergency care. 
  • In women, changes in your ovaries may happen that may cause menstrual bleeding to become irregular or stop, and may impair fertility. 

Note: Some of the side effects above are very rare. If you have concerns and/or questions, please discuss them with your medical team.
