How is a high red blood cell count treated?
If a medical condition is causing a high red blood cell count, your doctor may recommend a procedure or medication to lower it.
In a procedure called a phlebotomy, a health professional inserts a needle into your vein and drains blood through a tube into a bag or container. You might need to have this procedure on a repeated basis until your red blood cell level is close to normal.
If you are diagnosed with the bone marrow disease polycythemia vera, your doctor may also prescribe a medicine called hydroxyurea to slow your body’s production of red blood cells. You’ll need to see your doctor regularly while taking hydroxyurea to be sure your red blood cell level does not drop too low.
