This is not a complete list of doxorubicin drug interactions. Ask your doctor or pharmacist for more information.
Doxorubicin may cause serious side effects including:
- Heart problems. Doxorubicin may cause heart problems that may lead to death. These problems can happen during your treatment or months to years after stopping treatment. In some cases heart problems are irreversible. Your chance of heart problems is higher if you:
- already have heart problems
- have a history of radiation therapy or are currently receiving radiation therapy to your chest
- have had treatment with certain other anti-cancer medicines
- take other medicines that can affect your heart
Tell your doctor if you get any of these symptoms of heart problems:
- shortness of breath
- swelling of your feet and ankles
- fast heartbeat
Your doctor should do tests to check your heart before, during, and after your treatment with doxorubicin.
- Secondary cancers. Some people who have received doxorubicin have developed acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). Your chance of developing a secondary cancer is higher if you receive doxorubicin along with other anti-cancer medicines or with radiation therapy.
- Decreased blood cell counts. Doxorubicin can cause a severe decrease in neutrophils (a type of white blood cells important in fighting in bacterial infections), red blood cells (blood cells that carry oxygen to the tissues), and platelets (important for clotting and to control bleeding). Your doctor will check your blood cell count during your treatment with doxorubicin and after you have stopped your treatment.
Do not receive doxorubicin if:
- your blood cell counts are too low: platelets (which help your blood to clot), red blood cells (which help to carry iron and oxygen throughout your body), and white blood cells (which help to fight infection)
- you have a severe liver problem
- you have had a recent heart attack or have severe heart problems
- you have had previous treatment with doxorubicin or certain other anticancer medicines and received the maximum dose allowed
- you are allergic to certain other anti-cancer medicines, doxorubicin hydrochloride, or any other ingredient in doxorubicin.
Talk to your doctor before receiving doxorubicin if you have any of the conditions listed above.
Avoid receiving live vaccines during treatment with doxorubicin. Talk to your doctor to find out which vaccines are safe for you while receiving doxorubicin.
Rubex Food Interactions
Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of doxorubicin there are no specific foods that you must exclude from your diet when receiving doxorubicin.
Before you receive doxorubicin, tell your doctor if you:
- have heart problems
- have had radiation treatment or currently receiving radiation therapy
- are over the age of 50
- have liver problems
- plan to receive any vaccines
- have any other medical conditions
- are pregnant or breastfeeding
Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements. Doxorubicin can interact with other medicines. Do not start any new medicine before you talk with the doctor that prescribed doxorubicin.
Rubex and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant. Doxorubicin can harm your unborn baby. Women who may become pregnant should use effective birth control (contraception). Talk to your doctor about the best way to prevent pregnancy while receiving doxorubicin.
Rubex and Lactation
Tell your doctor if you are breastfeeding or plan to breast feed. Doxorubicin can pass into your breast milk and harm your baby. You and your doctor should decide if you will receive doxorubicin or breastfeed. You should not do both.
- Your doctor will prescribe doxorubicin in an amount that is right for you.
- Doxorubicin will be given to you by intravenous (IV) infusion into your vein.
- Your doctor will do regular blood tests to check for side effects of doxorubicin.
- Before receiving doxorubicin you may receive other medicines to prevent or treat side effects.
- Caregivers of children receiving doxorubicin should take precautions (such as wearing latex gloves) to prevent contact with the patient’s urine and other body fluids for at least 5 days after each treatment.

Doxorubicin is usually administered by a healthcare provider in a medical setting making it unlikely for an overdose to occur. However, if overdose is suspected, seek emergency medical attention.
Keep all appointments with your doctor and the laboratory. Certain laboratory tests may be required to monitor your body's response to doxorubicin.
Rubex FDA Warning
- Severe local tissue necrosis will occur if there is extravasation during administration. Doxorubicin must not be given by the intramuscular or subcutaneous route.
- Myocardial toxicity manifested in its most severe form by potentially fatal congestive heart failure (CHF) may occur either during therapy or months to years after termination of therapy. The probability of developing impaired myocardial function based on a combined index of signs, symptoms and decline in left ventricular ejection fraction (LVEF) is estimated to be 1 to 2% at a total cumulative dose of 300 mg/m2 of doxorubicin, 3 to 5% at a dose of 400 mg/m2, 5 to 8% at 450 mg/m2 and 6 to 20% at 500 mg/m2. The risk of developing CHF increases rapidly with increasing total cumulative doses of doxorubicin in excess of 400 mg/m2. Risk factors (active or dormant cardiovascular disease, prior or concomitant radiotherapy to the mediastinal/pericardial area, previous therapy with other anthracyclines or anthracenediones, concomitant use of other cardiotoxic drugs) may increase the risk of cardiac toxicity. Cardiac toxicity with doxorubicin may occur at lower cumulative doses whether or not cardiac risk factors are present. Pediatric patients are at increased risk for developing delayed cardiotoxicity.
- Secondary acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) have been reported in patients treated with anthracyclines, including doxorubicin. The occurrence of refractory secondary AML or MDS is more common when anthracyclines are given in combination with DNA-damaging anti-neoplastic agents or radiotherapy, when patients have been heavily pretreated with cytotoxic drugs, or when doses of anthracyclines have been escalated. The rate of developing secondary AML or MDS has been estimated in an analysis of 8563 patients with early breast cancer treated in 6 studies conducted by the National Surgical Adjuvant Breast and Bowel Project (NSABP), including NSABP B-15. Patients in these studies received standard doses of doxorubicin and standard or escalated doses of cyclophosphamide (AC) adjuvant chemotherapy and were followed for 61,810 patient years. Among 4483 such patients who received conventional doses of AC, 11 cases of AML or MDS were identified, for an incidence of 0.32 cases per 1000 patient years (95% CI, 0.16 to 0.57) and a cumulative incidence at 5 years of 0.21% (95% CI, 0.11 to 0.41%). In another analysis of 1474 patients with breast cancer who received adjuvant treatment with doxorubicin-containing regimens in clinical trials conducted at University of Texas M.D. Anderson Cancer Center,the incidence was estimated at 1.5% at 10 years. In both experiences, patients who received regimens with higher cyclophosphamide dosages, who received radiotherapy, or who were aged 50 or older had an increased risk of secondary AML or MDS. Pediatric patients are also at risk of developing secondary AML.
- Dosage should be reduced in patients with impaired hepatic function.
- Severe myelosuppression may occur.
- Doxorubicin should be administered only under the supervision of a physician who is experienced in the use of cancer chemotherapeutic agent.
