How does this medication work? What will it do for me?
Epirubicin belongs to the group of cancer-fighting medications known as antineoplastics, and specifically to the family of antineoplastics called anthracyclines. It is used alone or in combination with other antineoplastics to treat many types of cancer including breast cancer, lung cancer, ovary cancer, stomach cancer, and lymphoma.
Epirubicin prevents the growth of cancer cells by interfering with the genetic material DNA, which is necessary for reproduction of cells.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop receiving this medication without consulting your doctor.
What form(s) does this medication come in?
Each mL of sterile, ready-to-use, red-orange, isotonic, non-preserved solution contains epirubicin HCl 2 mg. Nonmedicinal ingredients: sodium chloride USP 9 mg, water for injection q.s, and hydrochloric acid for pH adjustment.
How should I use this medication?
The recommended dose of epirubicin varies widely according to the specific condition being treated, the response to therapy, the other medications being used, and the body size of the recipient person receiving treatment.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications.
Epirubicin is usually injected into a vein through a specially prepared site on the skin. Doses are usually given at 3- to 4-week intervals, either alone or with other medications used to treat cancer. Some dosing schedules suggest that smaller doses be given on a weekly basis. Very careful handling of this medication is required. Epirubicin is always given under the supervision of a doctor in a hospital or similar setting with access to sterile equipment for preparation.
As well as interfering with the genetic material DNA of cancer cells, epirubicin can interfere with some of your normal cells. This can cause a number of side effects such as hair loss and mouth sores. Keep track of any side effects and report them to your doctor as suggested in the section, "What side effects are possible with this medication?"
It is important this medication be given exactly as recommended by your doctor. If you miss an appointment to receive epirubin, contact your doctor as soon as possible to reschedule your appointment.

Are there any other precautions or warnings for this medication?
Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Anemia: This medication can reduce the number of red blood cells in the body, causing anemia. Red blood cells are responsible for carrying oxygen through the body, where it is used by the muscles and other tissues. If you develop symptoms of anemia, such as weakness, dizziness, or shortness of breath, contact your doctor.
Blood clotting: This medication can reduce the number of platelet cells in the blood. Platelets help the blood to clot, and a shortage could make you bleed more easily. Tell your doctor of any signs that your blood is not clotting as quickly. Such symptoms may include black and tarry stools, blood in the urine, easy bruising, or cuts that won't stop bleeding.
Fertility: Epirubicin can cause changes to sperm in men, possibly causing birth defects. Women may experience reduced or stopped ovulation or menstruation. In rare cases, women may experience premature menopause. Both women and men receiving epirubicin should use effective contraceptive methods.
Gout and kidney stones: Epirubicin may increase the levels of uric acid in the body, increasing the risk of developing gout or kidney stones. If you develop painful, warm, and swollen joints or difficulty with urination, contact your doctor as soon as possible. People with a history of gout or kidney stones should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart disease: Epirubicin may cause heart failure during treatment or after treatment has finished. The risk of abnormal heart rhythm, congestive heart failure, and a weakened heart (cardiomyopathy) is increased for people with preexisting heart disease. People with heart disease or an increased risk of heart disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infection: As well as killing cancer cells, this medication can reduce the number of cells that fight infection in the body (white blood cells). Avoid contact with people with contagious infections and tell your doctor if you begin to notice signs of an infection, such as fever or chills.
Secondary leukemia: There is some evidence to suggest that people who receive treatment with epirubicin are at an increased risk of developing acute myeloid leukemia (AML). Talk to your doctor if you have concerns.
Pregnancy: Although there is no conclusive information regarding the effects of epirubicin during pregnancy, due to the potential for toxic effects, this medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if epirubicin passes into breast milk. If you are a breast-feeding mother and are receiving this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The risk of heart problems resulting from the use of epirubicin is greater in children under 2 years of age.
