1. WHAT AZATHIOPRINE TABLETS ARE AND WHAT THEY ARE USED FOR
Azathioprine belongs to a group of medicines called immunosuppressants. Azathioprine helps to reduce or suppress your body’s own immune system. Your immune system helps to protect you against infections. However, sometimes it can produce illness and unwanted effects. For example, if you have just had an organ transplant, your immune system will try to reject the new organ. Azathioprine helps to prevent this immune response, and so allows the organ to carry on working. It is therefore used together with other medicines such as corticosteroids to · improve the survival of organ transplants
Azathioprine is also used to treat conditions caused by your immune system overreacting or reacting abnormally. For example:
· Rheumatoid arthritis (inflammation and pain in your joints)
· Hepatitis (inflamed liver)
· Systemic lupus erythematosus (a disease which affects your skin and major organs)
· blood disorders such as thrombocytopenia (reduced numbers of blood cells called platelets). This can affect blood clotting and increase the risk of bleeding or bruising.
· haemolytic anaemia (when you do not have enough red blood cells)
· Pemphigus blisters and sores on your skin
· dermatomyositis (inflammation of your muscles and skin)
· polyarteritis nodosa (inflammation of your blood vessels)
For these conditions, Azathioprine may be used alone, or in combination with other medicines.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE AZATHIOPRINE TABLETS
Do not take Azathioprine if you
· are allergic to azathioprine, to mercaptopurine (a medicine used to treat leukaemia, a cancer of the white blood cells) or any of the other ingredients of this medicine (listed in section 6).
· Are pregnant or intend to become pregnant
·Are breast-feeding.
Warnings and precautions
Talk to your doctor or pharmacist before taking this medicine if you:
· know you have a metabolic abnormality called Lesch-Nyhan syndrome. Azathioprine is not recommended if you have this condition.
· know you have a shortage of a liver enzyme called thiopurine methyltransferase (TPMT). TPMTbreaks down azathioprine and other medicines.
· have liver or kidney disease. You may have to take a lower dose and your doctor will closely monitor you.
· have ever suffered from chickenpox or shingles.
If you are receiving immunosuppressive therapy, taking Azathioprine could put you at greater risk of:
· tumours, including skin cancer. Therefore, when taking Azathioprine, avoid excessive exposure to sunlight, wear protective clothing and use protective sunscreen with a high protection factor.
· lymphoproliferative disorders
Treatment with Azathioprine increases your risk of getting a type of cancer called a lymphoproliferative disorder. With treatment regimen containing multiple immunosuppressants (including thiopurines), this may lead to death.
A combination of multiple immunosuppressants, given concomitantly increases the risk of disorders of the lymph system due to a viral infection (Epstein-Barr virus (EBV)-associated lymphoproliferative disorders).
Taking Azathioprine could put you at greater risk of:
· developing a serious condition called Macrophage Activation Syndrome (excessive activation of white blood cells associated with inflammation), which usually occurs in people who have certain types of arthritis.
Chickenpox /Shingles infection
Infection with chickenpox or shingles can become severe in patients taking immunosuppressive medicine. Therefore you should avoid contact with anyone suffering from chickenpox or shingles.
Your doctor will need to monitor you closely throughout your treatment. You should, therefore, visit your doctor regularly whilst taking Azathioprine so your condition can be checked. You will need to have your blood count checked at least once a week for the first two months of treatment and then monthly.
Other medicines and Azathioprine
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription, or the following:
· other immunosuppressants e.g. ciclosporin, methotrexate, tacrolimus
· medicines to treat cancer e.g. doxorubicin
· allopurinol, oxipurinol or thiopurines (for gout or kidney stones)
· cimetidine (for gut or stomach ulcers)
· furosemide (‘water tablets’)
· penicillamine (for rheumatoid arthritis)
· warfarin (to ‘thin’ the blood)
· captopril (for blood pressure or heart failure)
· indomethacin (an anti-inflammatory)
· co-trimoxazole (an antibiotic)
· mesalazine, olsalazine, sulfasalazine or balsalazide (mainly used to treat ulcerative colitis).
If you are going to have an operation, tell your doctor or the hospital staff as Azathioprine can interact with medicines called muscle relaxants (e.g. succinylcholine or tubocurarine), which you might be given during your operation.
If you are going to have a vaccination, tell your doctor as some vaccines should not be given or may be less effective, when given together with Azathioprine.
Pregnancy and breast-feeding
Do not take Azathioprine if you are pregnant, become pregnant, or suspect you may already be pregnant as the product could harm your baby (see section 2 “Do not take Azathioprine” above). Contact your doctor as soon as possible for advice. Do not take Azathioprine if you are planning to have a baby. This applies to both men and women.

· you have any signs of a viral, fungal or bacterial infection or fever. Infections are very common if you are taking Azathioprine after an organ transplant, and with another immunosuppressant or corticosteroid.
· low levels of white blood cells that means you are more likely to catch infections.
Common (may affect up to 1 in 10 people):
· reduction in blood platelets which increase the risk of bleeding or bruising
Uncommon (may affect up to 1 in 100 people):
· allergic reactions which may cause: feeling generally unwell, dizziness, nausea (feeling sick), vomiting (being sick), diarrhoea, fever, chills, rash or red spots, muscle or joint pain, problems with your kidneys (which may cause changes in the amount and colour of your urine), problems with your liver (which may cause yellowing of your skin and whites of your eyes), or a fall in blood pressure (hypotension) which may cause light-headedness or sweating.

Rare (may affect up to 1 in 1,000 people):
· various types of cancers including blood, lymph and skin cancers

Also, severe diarrhoea may happen, especially if you are being treated for inflammatory bowel disease.

· inflammation of the lungs which can cause weakness, breathlessness, cough and fever.
