About busulfan

Busulfan is used to treat chronic myeloid leukaemia (CML). This is a cancer of blood-forming cells in the bone marrow. Abnormal cells gradually fill the bone marrow and spill into the bloodstream, which increases the number of white cells in your blood. The disease typically develops very slowly and symptoms such as anaemia, bleeding problems or infections may not occur for many years after the start of the condition.

Busulfan is also used during preparation for stem cell transplantation. This is a procedure in which blood cells growing in a healthy donor's bone marrow are transferred to help produce healthy cells in another person's bone marrow.

Busulfan works by stopping cells from multiplying. It does this by binding to and damaging the DNA in cells. This helps stop the increase in the number of blood cells.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking busulfan it is important that your doctor or pharmacist knows:

• Si estás embarazada, intentando tener un bebé o amamantando.

• If you have recently had radiotherapy.

• Si tiene algún problema con el funcionamiento de su hígado o riñones.

• If you have a breathing problem such as asthma or chronic obstructive pulmonary disease (COPD).

• Si tienes una infección o te sientes mal.

• If you have epilepsy or have ever had a fit (seizure).

• Si tienes un trastorno sanguíneo hereditario raro llamado porfiria.

• If you have ever had gout (painful or swollen joints, usually in the toes).

• Si está tomando o usando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

• Si alguna vez has tenido una reacción alérgica a un medicamento.

• Busulfan will be prescribed for you by a specialist doctor who is experienced in treating your condition. Take the tablets exactly as your doctor tells you to. Your dose will depend on the reason why you are taking it. If you are unsure about how to take the tablets, or if you have any other concerns, you should contact your doctor or hospital clinic for advice.

• Swallow the tablets with plenty of water. Do not break, crush or chew them. You can take busulfan tablets before or after meals.

• Before you start this treatment, read any printed information you have been given by your doctor and the leaflet from inside your pack of tablets. The leaflet will give you more information about busulfan and a full list of possible side-effects from taking it.

• You may need to take busulfan for several weeks or months. Do not stop taking busulfan without speaking with your doctor first.

• If you are sick (vomiting) shortly after taking a dose, or if you forget a dose, contact your doctor or clinic for advice on what to do. You will be told whether to take the dose again, or wait until the next dose is due.

• You must try to keep your regular appointments with your doctor or hospital. This is so your doctor can check on your progress. You will need to have regular check-ups during your treatment to monitor for unwanted side-effects.

• Busulfan lowers the number of white cells in your blood, increasing the chance of you getting an infection. If possible, avoid people who you know are ill, and let your doctor know if you feel you are getting an infection.

• It is important that you do not get pregnant or father a child while you are taking busulfan. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner.

• If you intend to have children in the future, you should ask your doctor for advice about family planning before you begin taking busulfan. This is particularly important if you are a man, as there is a risk of reduced fertility after busulfan treatment.

• While you are taking busulfan and for a while after you stop treatment, do not have any immunisations (vaccinations) without talking to your doctor first. Busulfan lowers your body's resistance and there is a chance that you may get an infection from some vaccines.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking busulfan.

• If you buy any medicines, check with your doctor or a pharmacist that they are suitable for you to take with your other medicines.
