It can also lower the number of platelets, which are necessary for proper blood clotting. Avoid people with infections and check with your doctor if you have symptoms of an infection such as a fever or chills, a cough or hoarseness, lower back or side pain, or painful or difficult urination. Call your doctor if you have any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
