Nausea, vomiting, diarrhea, and loss of appetite may occur. Nausea and vomiting can be severe. In some cases, drug therapy may be needed to prevent or relieve nausea and vomiting. Not eating before your treatment may help relieve vomiting. Changes in diet and lifestyle, such as eating several small meals and limiting activity, may help lessen some of these effects. If any of these effects continue or worsen, notify your doctor or pharmacist.
Doxorubicin may give a reddish color to your urine, tears, and sweat. This effect may start in the first hours after treatment and may last up to several days. This is a normal effect of the drug and should not be mistaken for blood in your urine.
Temporary hair loss may occur. Normal hair growth should return after treatment has ended.
Nail changes (including fungal infections in the nail beds) may rarely occur.

Within days to weeks after doxorubicin treatment, a serious skin reaction that looks likes a severe sunburn (radiation recall) may develop on any area of skin that has been previously treated with radiation. Tell your doctor immediately if you develop skin redness, pain, tenderness, swelling, peeling, or blisters. Your doctor may prescribe medication to help your skin heal faster and reduce the swelling. In addition, you should avoid prolonged sun exposure, tanning booths and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
