Managing head injuries.

People who have hemophilia must be particularly alert to the threat of head injuries, which can be difficult to detect. You may not actually see a head injury without a test like a computerized tomography (CT) scan or magnetic resonance imaging (MRI). Because head bleeds can be life-threatening, it’s important to know the signs and symptoms of a head injury and to report them to your doctor right away.

Signs and symptoms of a head injury:

  • Headache that doesn’t go away or gets worse in 24 hours
  • Drowsiness or trouble waking up
  • Any changes in vision
  • Dizziness or trouble walking straight
  • Nausea and vomiting (when you’re not sick)
  • Slurred speech
  • Confusion
  • Loss of consciousness
  • Fussiness (that may become inconsolable) in small children

In case of a possible head injury:

  • Always follow the instructions provided by your Hemophilia Treatment Center (HTC) or physician
  • If on home infusion, infuse factor to raise levels between 80 percent and 100 percent
  • If you are not on home infusion, or after home infusion of factor, get medical care right away
    • Call or have someone call 911 if you lose consciousness or have other medical problems
    • Go to the emergency room for an exam and tests (CT scan or MRI)
    • Call your hemophilia treatment center (HTC) or CVS Specialty Hemophilia CareTeam
  • Avoid or hold off on any pain medication until your doctor prescribes it


  • Head bleeds can happen from a major injury or a seemingly small one.
  • Bleeding in the head can be slow. Signs and symptoms may appear gradually, even over several days.
  • A head bleed may be unnoticeable. Even though you may not see any signs of injury (like bumps or bruises), bleeding may still be occurring inside the head.
  • You may need treatment with factor for a period of time after a bleeding episode.
