1. What Azatioprine Mylan is and what it is used for
Azathioprine Mylan contains the active substance azathioprine. The
belongs to a group of medicines called immunosuppressants. Drugs belonging to this group suppress the immune system.
Azathioprine Mylan can be used to help the body accept a transplanted organ, such as a new kidney or liver or a new heart. Azathioprine Mylan can also be used to treat certain diseases that are caused by the immune system attacking the body’s own tissues (autoimmune diseases).
Autoimmune diseases can be:
severe rheumatoid arthritis (a disease in which the immune system attacks cells surrounding joints and causes swelling, pain, and stiffness in the joints)
systemic lupus erythematosus (a disease in which the immune system attacks several organs and tissues in the body, such as the skin, joints, kidneys, brain and other organs and causes severe fatigue,
fever, stiffness and joint pain)
dermatomyositis and polymyositis (a group of diseases that cause inflammation in the muscles, muscle weakness, and rash)
autoimmune chronic active hepatitis (a disease in which the immune system attacks liver cells and causes hepatitis, fatigue, muscle aches, yellowing skin, and fever)
pemphigus (a disease in which the immune system attacks skin cells and causes severe blistering of the skin, mouth, nose, throat, and genitals)
polyarteritis nodosa (a rare disease that causes inflammation of the blood vessels)
autoimmune hemolytic anemia (a serious blood disorder in which the body destroys red blood cells faster than they are formed, with symptoms such as weakness and shortness of breath)
chronic refractory idiopathic thrombocytopenic purpura (a disease with low platelet counts that can cause mild or excessive bruising or bleeding).
Azathioprine Mylan can also be used to treat inflammatory bowel disease ( Crohn’s disease or ulcerative colitis ).
Your doctor has chosen this medicine because it is suitable for you and your illness.
Azathioprine Mylan can be used alone, but is more often used with other medicines.
Azathioprine contained in Azathioprine Mylan may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
What you need to know before you take Azathioprine Mylan
Do not take Azathioprine Mylan
- if you are allergic to azathioprine or any of the other ingredients of this medicine (listed in section 6)
- if you are allergic to mercaptopurine (a medicine similar to azathioprine which is the active substance in Azathioprine Mylan).
Warnings and cautions
Talk to your doctor before taking Azathioprine Mylan:
- if you have recently received or will receive a vaccination. If you are taking Azathioprine Mylan, you should not receive a live vaccine (eg flu , measles, BCG vaccine, etc.) until your doctor thinks it is safe for you. This is because some vaccines can cause infection if you get them while you are taking Azathioprine Mylan.
- if you have a genetic disorder called Lesch-Nyhan syndrome. This is a rare inherited disease caused by a lack of HPRT, ie hypoxantinguanin phosphoribosyltransferase.
- if you have liver or kidney problems
- if you have a genetic disease called TPMT deficiency (where the body produces too little of an enzyme called thiopurine methyltransferase)
- if you have had chickenpox or shingles
- if you have had hepatitis B (a liver disease caused by a virus )
- if you are going to have an operation (this is because medicines including tubocurarine or
- succinylcholine used as a muscle relaxant during surgery may affect or be affected by Azathioprine Mylan.) Before surgery, tell your anesthetist that you are being treated with Azathioprine Mylan.
NUDT15 gene mutation
If you have a hereditary mutation in the NUDT15 gene (a gene that is involved in the breakdown of azathioprine in the body), the risk is higher that you will get an infection and hair loss and the doctor can give you a lower dose in this case .
If you are unsure if any of the above apply to you, speak up
with a doctor, nurse or
pharmacy staff before taking Azathioprine Mylan.
Your doctor will ask you to take regular blood tests while you are taking Azathioprine Mylan to check for any changes (see section 3 “How to take Azathioprine Mylan”). If treatment with Azathioprine Mylan is continued for a long time, blood tests are generally taken less frequently.
Taking immunosuppressive therapy and taking Azathioprine Mylan may increase your risk of:
- tumor er, including skin cancer. Therefore, when taking Azathioprine Mylan, you should avoid excessive sunbathing as well as wear protective clothing and use sunscreen with a high protection factor.
- lymphoproliferative disorders
- Treatment with Azathioprine Mylan increases your risk of developing a type of cancer called lymphoproliferative disorder. During treatment regimens that contain several immunosuppressive drugs (including thiopurines), this can lead to death.
- a combination of several concomitant immunosuppressive drugs increases the risk of disorders of the lymphatic system due to a viral infection (lymphoproliferative disorders associated with the Epstein-Barr virus ( EBV )).
- development of a serious condition called macrophage activation syndrome (excessive activation of white blood cells associated with inflammation ), which usually occurs in people with certain types of arthritis
severe chickenpox or shingles infection. When you take Azathioprine Mylan
- therefore avoid contact with people who have chickenpox or shingles
- previous hepatitis B infection that becomes active again
- other infections such as PML ( progressive multifocal leukoencephalopathy) which is an opportunistic infection . If you experience any signs of infection, consult a doctor (see section 4 “Possible side effects”).
Other medicines and Azathioprine Mylan
Tell your doctor if you are taking, have recently taken, or might take any other medicines. This is because Azathioprine Mylan may affect the way some medicines work. Some other medicines may also affect the way Azathioprine Mylan works. Tell your doctor specifically and you are taking or plan to take:
- ribavirin (used to treat viral infections)
- methotrexate (mainly used to treat cancer)
- allopurinol, oxypurinol, thiopurine, or other xanthine oxidase inhibitors, such as febuxostat (used mainly to treat gout)
- penicillamine (mainly used to treat rheumatoid arthritis )
- ACE inhibitors (mainly used to treat high blood pressure )
- anticoagulants , such as warfarin or acenocoumarin (used to prevent blood clots)
- cimetidine (used to treat stomach ulcers and digestive problems)
- indomethacin (used as an analgesic and anti-inflammatory)
- cytostatics (drugs used to treat various types of cancer)
- aminosalicylates, e.g. olsalazine, mesalazine or sulfasalazine (used mainly to treat ulcerative colitis and Crohn’s disease )
- trimethoprim sulfa ( antibiotics used to treat bacterial infections)
- infliximab (mainly used to treat ulcerative colitis and Crohn’s disease )
- Before undergoing surgery, tell your anesthetist that you are being treated with azathioprine, as the muscle relaxants used in anesthesia may affect or be affected by azathioprine.
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking Azathioprine Mylan.
Getting vaccinated during treatment with Azathioprine Mylan
If you will be vaccinated, talk to a doctor or nurse before receiving the vaccination. If you are taking Azathioprine Mylan, you should not receive a live vaccine (eg flu , measles, BCG vaccine, etc.) until your doctor thinks it is safe for you.
