About tioguanine

اللوكيميا is a cancer of cells in the bone marrow. The cancerous cells in the bone marrow spill out into the bloodstream. Most types of leukaemia arise from cells which normally develop into white blood cells. There are several different types of leukaemia, and treatments for the different types vary. Tioguanine is a treatment used for ابيضاض الدم النخاعي الحاد (AML), ابيضاض الدم الليمفاوي الحاد (ALL) ,، و ابيضاض الدم النقوي المزمن (CML).

In cancers like leukaemia, certain cells in the body grow and multiply too fast. Anti-cancer medicines like tioguanine work by stopping the growth of the cancer cells. They do this by affecting the genetic material of the cells. This reduces the number of new cells that your body makes.

Before taking tioguanine

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 tioguanine, it is important that your doctor knows:

• إذا كنتِ حاملاً، أو تنوين إنجاب الأطفال في المستقبل.

• إذا كنت ترضعين.

• إذا سبق أن أخبرك طبيب بأنك تفتقر إلى بعض الإنزيمات التي تساعد في إزالة الأدوية من جسمك. على وجه الخصوص، أخبر طبيبك إذا كنت تعلم أن جسمك ينتج كمية قليلة من إنزيم يسمى ثيوبيورين ميثيل ترانسفيراز (TPMT).

• إذا كان لديك أي مشاكل في كيفية عمل الكبد أو الكلى لديك.

• إذا كنت تتناول أو تستخدم أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.
  

How to take tioguanine

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack and any other written information you are given. The manufacturer's leaflet will give you more information about tioguanine and a full list of the side-effects which you may experience from taking it.

• Tioguanine will be prescribed for you by a doctor who is experienced in treating your condition. You will be prescribed short courses of tioguanine. Your dose (that is the number of tablets you will need to take) will be calculated from your weight and height, and may also depend upon other treatment you are having. It is important that you take the tablets exactly as your doctor tells you to. The dose you have been prescribed will be printed on the label of your pack to remind you.

• Your body may absorb slightly less tioguanine if you take the tablets with food - for this reason it is preferable to take the tablets at least one hour before a meal or two hours after a meal.

• Swallow the tablets whole with a drink of water.

• If you forget to take a dose, take the next dose when it is due and remember to let your doctor know about the missed dose. Do not take two doses together to make up for a missed dose.

تحقيق أقصى استفادة من علاجك

• You must try to keep your regular appointments with the doctor or hospital. This is so your progress can be checked. You will need to have regular weekly blood tests during your treatment to check that your liver stays healthy.

• You must avoid getting pregnant or fathering a child while you are on tioguanine. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. Many anti-cancer treatments are associated with reduced fertility (particularly in men), so you may also want to ask your doctor for family planning advice if you intend to have children in the future.

• If you are due to have an operation or dental treatment, tell the person carrying out the treatment that you are taking tioguanine.

• Do not have any immunisations (vaccinations) while you are taking this medicine and for several months afterwards, without talking with your doctor first. Tioguanine lowers your body's resistance and there is a chance that you may get an infection from some vaccines.

• Tioguanine may cause your skin to become more sensitive to sunlight than normal. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF) of at least 15, especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

• If you buy any medicines, check with a pharmacist that they are suitable to take with tioguanine.

• يجب التخلص من أي أقراص أو أدوية غير مرغوب فيها بطريقة خاصة - اسأل صيدليتك المحلية أو صيدلية المستشفى للحصول على نصيحة حول ما يجب القيام به.
