- This medication decreases bone marrow function, an effect that may lead to a low number of blood cells such as red cells, white cells, and platelets. This effect can cause anemia, decrease your body's ability to fight an infection, or cause easy bruising/bleeding. Tell your doctor right away if you develop any of the following symptoms: signs of infection (such as sore throat that doesn't go away, fever, chills), easy bruising/bleeding, pale skin, unusual tiredness.<br /><br /> Hydroxyurea may cause other cancers (such as secondary leukemia, skin cancer). Protect your skin from the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps.<br /><br />Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you notice any symptoms of cancer, such as swollen glands, sudden weight loss, night sweats, or unusual skin growths/moles.
