Caregivers should take precautions (such as wear gloves) to prevent contact with the patient's urine or other body fluid for at least 5 days after treatment. Consult your pharmacist.

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 last or get worse, tell your doctor or pharmacist promptly.

Pain or sores in the mouth and throat may occur. Brush your teeth carefully/gently, avoid using mouthwash that contains alcohol, and rinse your mouth often with cool water mixed with baking soda or salt. It may also be best to eat soft, moist foods.

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.
