You may be more likely to experience side effects such as nausea; vomiting; diarrhea; swelling; high blood sugar; heart rhythm abnormalities; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. You should seek medical attention if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, or pain and burning during urination.
