Your doctor will check the results of your blood tests and adjust your treatment to reduce your risk for these side effects. Seek immediate medical attention if you develop signs of anemia (such as unusual tiredness, fast breathing, pale skin, fast heartbeat), signs of infection (such as fever, chills, cough, persistent sore throat), and signs of bleeding (such as easy bruising/bleeding, nose bleeds, bleeding gums, bloody/black/tarry stools, vomit that looks like coffee grounds).
