Cytoxan Warnings and Precautions

Understanding Cytoxan warnings and precautions prior to starting the medication can help ensure a safe treatment process. Cytoxan can potentially cause fertility problems, increase the risk of developing certain cancers in the future, decrease the bone marrow's ability to produce blood cells, and cause bladder damage in some people. Among the people who should not take Cytoxan are those who are allergic to any components of the drug and those who have severe bone marrow depression.
