See also Warning section.

Nausea, vomiting, diarrhea, abdominal pain, flushing, or skin/nail color changes may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If these effects last or get worse, tell your doctor or pharmacist promptly.

This medication may cause your urine to turn a reddish color. This is a normal, harmless effect of the drug that usually stops within 2 days after each dose and should not be mistaken for blood in your urine.

Temporary hair loss is a common side effect. Normal hair growth should return after treatment has ended.

Severe nausea, vomiting, and diarrhea may rarely cause dehydration. Contact your doctor promptly if you notice any symptoms of dehydration such as unusual decreased urination, unusual dry mouth/increased thirst, lack of tears, dizziness/lightheadedness, or pale/wrinkled skin.

Epirubicin sometimes causes side effects due to the rapid destruction of cancer cells (tumor lysis syndrome). To lower your risk, your doctor may add a medication and tell you to drink plenty of fluids. Tell your doctor right away if you have symptoms such as:
