1. WHAT EPOSIN IS AND WHAT IT IS USED FOR
2. WHAT YOU NEED TO KNOW BEFORE YOU USE EPOSIN
EPOSIN should not be administered to you: Before you begin treatment with EPOSIN, you and your doctor should talk about the good EPOSIN will do as well as the risk of using it.
- if you are allergic to etoposide or any of the other ingredients in the formulation. Tell your doctor and pharmacist if you are allergic to any other substances, such as foods, preservatives, or dyes (listed in section 6)
- if you have chickenpox, existing or recent (including recent exposure) or shingles
- if you suffer from kidney or liver problems
- if you have a weak immune system (from disease or from treatment with other cancer medicines)
- if you have decreased ability or inability of the bone marrow to make white blood cells, red blood cells, and platelets
- if you have a weak immune system and you are being vaccinated against yellow fever at the same time
- if you are pregnant or breastfeeding your baby.
Warnings and precautions:
Tell your doctor or healthcare provider before being given the injection: Take special care with EPOSIN:
- if you have had radiotherapy or chemotherapy recently
- EPOSIN can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill
- acute leukaemia can occur after the treatment of EPOSIN
- make sure you tell your doctor of any other medical problems especially if you have had an infection recently. Your blood will need to be tested on a regular basis to ensure your blood cells do not get too low
- tell your doctor if you have allergic reactions such as low blood pressure, irregular heartbeat, difficulty in breathing, chills, fever, flushing
- tell your doctor or nurse right away if you notice any reactions at the injection site, as the infusion might need to be stopped.
- if you have low levels of a protein called albumin in your blood.
- tell your doctor if you have problems with your liver.
- tell your doctor if you have problems with your kidney. If you have reduced liver or kidney function, your doctor may also want you to take regular blood tests to monitor these levels.
Children and adolescents:
Safety and efficacy in paediatric patients have not been established.
Other medicines and EPOSIN:
Always tell your healthcare provider if you are taking any other medicine. (This includes all complementary or traditional medicines). Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.
Tell your doctor or pharmacist if you are using other medicines such as:
- the immunosuppressant ciclosporin (often given after an organ transplant) may increase the effect of EPOSIN
- cisplatin (used to treat cancer), as it may increase the effect of EPOSIN
- myelosuppressive (inhibiting bone marrow activity) medicines, as these may increase the effect of EPOSIN
- the blood clotting effect of anti-coagulants such as warfarin which are used to thin the blood may be reduced
- medicines for epilepsy such as phenytoin can reduce efficacy of EPOSIN
- the analgesic (used for pain) and fever lowering medicines phenylbutazone, aspirin and aspirin related medicines (sodium salicylate) may increase the effect of EPOSIN
- vaccines for yellow fever or other live vaccines should not be given during treatment with EPOSIN.
Pregnancy, breastfeeding and fertility:
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, please consult your doctor, pharmacist or other healthcare provider for advice before receiving EPOSIN. EPOSIN must not be used during pregnancy (see section 2 WHAT YOU NEED TO KNOW BEFORE YOU USE EPOSIN). Tell your doctor if you are pregnant or if you intend to have children as EPOSIN may cause foetal harm when administered during pregnancy. Be sure that you have discussed this with your doctor before receiving EPOSIN. Effective birth control to prevent pregnancy is advised during EPOSIN treatment and after the end of EPOSIN treatment for the following 6 months for women and for 3 months for men. It is advised that women of childbearing age should be advised not to fall pregnant while receiving EPOSIN. Tell your doctor right away if you think you have become pregnant while receiving EPOSIN. Men should not father a child whilst being treated with EPOSIN and until 3 months after treatment has finished. It is advised for men to consider sperm preservation before treatment with EPOSIN, because infertility after treatment can occur. You must not breastfeed while you are receiving EPOSIN. Tell your doctor if you are breastfeeding or if you intend to breastfeed during treatment with EPOSIN, because EPOSIN may cause serious side effects.
3. HOW TO USE EPOSIN
Do not share medicines prescribed for you with any other person. Safety and efficacy in paediatric patients have not been established. EPOSIN should be administered under the supervision of a doctor experienced in the use of cancer chemotherapeutic medicines. Severe bone marrow suppression may occur, complicated by bleeding or infection, which may be fatal. Your medicine will be given to you by injection into a vein under the direction of your doctor. Your doctor will decide what dose to give and number of days treatment you will receive depending on your condition. The amount of EPOSIN you will receive depends on many factors, including your height and weight, your general health or other health problems, and the type of cancer you have. Your doctor will determine your exact dosage and schedule.
If you receive more EPOSIN than you should: Since a healthcare provider will administer EPOSIN he/she will control the dosage. However, in the event of overdosage your doctor will manage the overdosage.
If you forget to use EPOSIN: Since a healthcare provider will administer EPOSIN, it is unlikely that the dose will be missed.
