The chemotherapy (“chemo”) drug “The Red Devil” is doxorubicin (Adriamycin), an intravenous injection with a clear, bright red color used to treat various cancers. It may cause your urine or other body fluids to turn a reddish-orange color for 1 to 2 days after a dose is given, which is normal and temporary. Doxorubicin can also cause harsh side effects such as heart toxicity (heart failure), secondary cancers, severe vomiting and total hair loss (alopecia).
