Answers to Frequently Asked Questions About Adriamycin®
Generic Name: doxorubicin (docks-oh-ROO-bi-sin)
Trade Name: Adriamycin® and Rubex®
For which conditions is Adriamycin approved? Doxorubicin is used for the treatment of several cancers, including bladder, bone, breast, endometrial, gastric, head and neck, kidney, leukemia, liver, lung, lymphomas, mesothelioma, multiple myeloma, neuroblastoma, ovarian, pancreas, prostate, sarcomas, stomach, testis (germ cell), thyroid, uterus, Wilms’ tumor, and Waldenström macroglobulinemia. It is important for patients to remember that physicians have the ability to prescribe medication for conditions other than those for which the drug has been approved by the FDA. Patients who have received a prescription of this drug for a condition other than which it is approved may wish to discuss this issue with their physician.
What is the mechanism of action? Doxorubicin belongs to a group of agents called anthracycline antitumor antibiotics. Doxorubicin produces its anti-cancer effects by binding to DNA and inhibiting the production of proteins necessary for sustaining life of a cell.
How is doxorubicin typically given (administered)? Doxorubicin is administered intravenously (into a vein). If doxorubicin escapes from the vein in which it is being administered, it may cause serious damage to tissue that it comes in contact with. Although patients will be monitored for this, they should tell their healthcare provider immediately if they experience pain, redness, or swelling at the site that doxorubicin is being administered. In addition, patients may experience a reaction to doxorubicin during treatment or immediately following administration. Patients should tell their healthcare providers if they are experiencing difficulty breathing, wheezing, swelling of throat, hives, or swelling of facial features.
How are patients typically monitored? Patients will usually have scheduled meetings with their healthcare provider while they are being treated with doxorubicin. Typically, blood will be drawn to check levels of blood cells and to monitor functions of some organ systems, such as the kidneys or liver. Patients may also undergo physical examinations, scans or other measures to assess side effects and response to therapy.
In addition, patients will have their heart function monitored prior to therapy with doxorubicin and at intervals during therapy, since damage to the heart, although rare, may occur from treatment. The risk of impaired heart function increases with cumulative doxorubicin therapy.
What are the common (occur in 30% or more of patients) side effects of treatment with doxorubicin?
- Low white blood cell levels – increases risk of infection
- Low red blood cell levels – increases risk of anemia
- Low platelet levels – increases risk of bleeding
- Nausea and vomiting
- Hair loss
What are the less common (occur in 10% to 29% of patients) side effects of treatment with doxorubicin?
- Watery eyes
- Abnormal color of urine (reddish or brownish)
- Darkening of skin at sites that received previous radiation
- Darkening of skin and nail beds
- Gastrointestinal ulcers, may lead to infections or bleeding
- Lack of appetite
- Mouth sores
What are the possible late side effects of treatment with doxorubicin? Treatment with doxorubicin may cause damage to the heart, and inhibits its ability to properly pump blood. Patients will be monitored for this side effect; however, they should notify their healthcare provider if they feel chest pain or tightness or extreme fatigue. In addition, patients treated with doxorubicin are at a slightly increased risk of developing a secondary malignancy caused by treatment, such as leukemia. A secondary malignancy is a new and unrelated cancer that occurs in an individual as a result of previous treatment with radiation or chemotherapy. Tumor lysis syndrome may also occur after using doxorubicin. Patients should ask their physician about the possibility of developing a secondary malignancy as a result of their treatment.
This is not a complete list of side effects. Some patients may experience other side effects that are not listed here. Patients may wish to discuss with their physician the other less common side effects of this drug, some of which may be serious.
Some side effects may require medical attention. Other side effects do not require medical attention and may go away during treatment. Patients should check with their physician about any side effects that continue or are bothersome.
What can patients do to help alleviate or prevent discomfort and side effects?
- Pay careful attention to the physician’s instructions and inform the physician of any side effects.
- Maintain adequate rest and nutrition.
- Wear sunscreen and protective clothing and try to minimize sun exposure.
- Drink plenty of fluids. (Patients should ask their physician about the amount of liquid to consume during a day.)
- If possible, avoid large crowds or people who are sick or not feeling well, as this drug may leave some patients susceptible to infection.
- Wash hands often to reduce the risk of infection.
- Eat small meals frequently to help alleviate nausea.
- If patients have been prescribed an anti-nausea medication, they should be sure to take the prescribed doses.
- Avoid activities that may cause injury or bruising.
- Use a soft toothbrush and an electric razor to prevent cuts on the mouth or skin.
- For mouth sores, patients should rinse their mouth three times a day with a salt and soda solution (8 ounces of water mixed with ½ to 1 tsp baking soda and/or ½ to 1 tsp salt) and brush their teeth with a soft toothbrush to help prevent the development of mouth sores.
Are there any special precautions patients should be aware of before starting treatment?
- Patients should inform their physician if they are pregnant, breastfeeding or planning a family in the near future. This drug may cause birth defects. It is important to use some kind of birth control while undergoing treatment. Also, patients may want to talk to their physician if they are considering having children in the future, since some drugs may cause fertility problems.

- Patients should inform their physician of any other medication they are taking (whether prescription or over-the-counter, including vitamins, herbs, etc.) as they may interfere with treatment.
