Patient Medication Information: uses, side effects, how to take - Epirubicin Hydrochloride Injection (Pfizer Canada)
ABOUT THIS MEDICATION
Epirubicin Hydrochloride Injection and cancer treatment:
What is Epirubicin Hydrochloride Injection used for:
Epirubicin Hydrochloride Injection alone or in combinaison with other anticancer drugs is used in the treatment of:
- Metastatic breast cancer
- Small cell lung cancer, advanced non-small cell lung cancer
- Stage III and IV ovarian cancer
- Metastatic and locally unresectable gastric carcinoma
Epirubicin Hydrochloride Injection in combination with other anticancer drugs is also used in the adjuvant treatment of early stage of breast cancer for pre- and peri-menopausal women.
What it does:
Epirubicin Hydrochloride Injection is a chemotherapy drug, often used in combination with other drugs to kill cancer cells. Most chemotherapy agents (including Epirubicin Hydrochloride Injection) work by killing rapidly dividing cells, such as cancer cells. This action can affect normal cells as well.
In breast cancer, it can be used following surgery and/or radiation as adjuvant or additional therapy. Here, it is used to kill cancer cells that have ‘escaped’ the tumour and could spread to other parts of the body (like the bones, liver, or lungs), where the cancer can grow again and recur. If breast cancer has spread to the lymph nodes in the axilla (armpit), there is higher chance of recurrence if no treatment is given. (The axillary lymph nodes normally drain fluid from the breast and arm.) The extent of the cancer cell spreading may be a factor when a chemotherapy regimen is chosen. BEFORE STARTING TREATMENT YOU AND YOUR DOCTOR SHOULD DISCUSS TREATMENT OPTIONS BEST SUITED TO YOU, TAKING INTO CONSIDERATION YOUR CONDITION AND OTHER HEALTH CONCERNS THAT YOU MAY HAVE.
In other cancers, chemotherapy can be used to reduce tumour size, or stop them from growing. Understand why your doctor has chosen the particular chemotherapy regimen to be used, and know all the risk and benefits before starting therapy.

PROPER USE OF THIS MEDICATION
How is Epirubicin Hydrochloride Injection given?
Some patients may receive Epirubicin Hydrochloride Injection through a vein in the arm (“intravenously” or “IV”) by their doctor or nurse, usually in the hospital, outpatient department or clinic.
If you are getting many injections over several weeks or months, for your convenience, your doctor may insert a catheter (thin tube) or port into a large vein in your body that is placed there as long as it is needed. Medicines get injected through the catheter or port rather than directly into a vein.
How much time does it take to get a treatment with
Epirubicin Hydrochloride Injection?
It usually takes about 5 minutes to inject Epirubicin Hydrochloride Injection. However, you may get other medicines before or after Epirubicin Hydrochloride Injection, so your entire treatment may last an hour or longer.
How long will I need treatment?
Your doctor will determine the length of your treatment based on your treatment goals, the medicines you receive, and how your body responds to those medicines. Adjuvant chemotherapy for breast cancer usually lasts 3 to 6 months, however.
Chemotherapy is usually given in cycles that include rest periods between treatments. The rest periods give your body a chance to build healthy new cells and regain your strength before your next treatment. Epirubicin Hydrochloride Injection is given in treatment cycles of 21 days or 28 days. You may receive one dose of Epirubicin Hydrochloride Injection every three or four weeks (on Day 1 of the cycle). Or, you may receive Epirubicin Hydrochloride Injection in two doses - one dose on Day 1 of the cycle, and another dose on Day 8. Your treatment cycle will depend on your medical condition and the other chemotherapy medicines you are getting.
Will I be able to work?
Some people work full time, while others work part time or wait until their chemotherapy treatments are finished. It depends on the type of job you have and the side effects you experience.
Is it okay to become pregnant or nurse a baby?
No. Epirubicin Hydrochloride Injection can be harmful to an unborn child. If there is any possibility that you may become pregnant, ask your doctor about using birth control to prevent pregnancy during your treatment with Epirubicin Hydrochloride Injection. Tell your doctor right away if you become pregnant during treatment. If you have been nursing, you should stop before starting treatment with Epirubicin Hydrochloride Injection. Ask your baby’s doctor to recommend a formula that would be best for your baby.
What should men consider when taking Epirubicin Hydrochloride Injection?
Men undergoing treatment with epirubicin should use effective contraceptive methods.
What happens after treatment?
After you have completed all your chemotherapy treatments, your doctor will check you regularly to make sure the cancer has not returned.
Overdose:
| If you think you are given more Epirubicin Hydrochloride Injection than you should; contact your doctor, nurse, or poison control centre immediately. |
Missed dose:
If you miss your scheduled treatment with the drug, contact your doctor as soon as possible to schedule your next treatment.
SIDE EFFECTS AND WHAT TO DO ABOUT THEM
Like all medicines, Epirubicin Hydrochloride Injection may cause side effects. Everyone reacts differently to chemotherapy and not all people will experience every side effect.
Common side effects include:
- hair loss, which is temporary and usually starts to grow back within 2 or 3 months after you have finished your treatments.
- increased risk of infection, as a result of low white blood cell count. The signs of infection include fever over 38°C (100°F), chills or sweating, sore throat or coughing, redness or swelling around a cut, wound or a catheter site, a burning feeling when you urinate, unusual vaginal itching or discharge.
- nausea and vomiting.
- fatigue, or feeling tired.
- mouth sores.
- Epirubicin Hydrochloride Injection is a red-orange coloured liquid and will make your urine turn red for a few days after treatment.
The kinds of side effects, how often they occur, and how bad they may be could be related to the dose of chemotherapy, or the regimen used.
Rare side effects include:
- Damage to the heart muscle, which can cause symptoms such as shortness of breath, swelling in the ankles, and fluid retention. If you have these symptoms, call your doctor right away. There are medicines to treat this condition.
- Secondary leukemia (less than 1% of patients) up to 5 years after treatment with Epirubicin Hydrochloride Injection.
The chances of developing heart damage or leukemia appear to be related to either how much chemotherapy you have received, or the dose of Epirubicin Hydrochloride Injection used. Be sure you discuss the risks and benefits of various chemotherapy options with your doctor, and understand the side-effects both immediate and long-term that you could have from your treatment before you start therapy.
