1. What Azathioprine 1A Farma is and what it is used for

Azathioprine 1A Farma tablets contain the active ingredient azathioprine which belongs to a group of medicines called immunosuppressive agents. Immunosuppressive agents reduce the strength of your immune system. Your doctor has prescribed Azathioprine 1A Farma tablets for one of the following conditions:

  • to help your body accept a transplanted organ
  • to control certain diseases where your immune system reacts to your own body.

Azathioprine 1A Farma tablets can also be used alone or in combination with other medicines to treat severe rheumatic disease, severe inflammation of the intestine ( Crohn’s disease or ulcerative colitis ), or to treat certain diseases where your immune system reacts to your own body ( autoimmune disease ) including severe inflammatory diseases of the skin, liver, arteries are and some blood disorders.

Azathioprine contained in Azathioprine 1A Farma may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist or other healthcare professional if you have any further questions and always follow their instructions.

NUDT15 gene mutation

If you have a hereditary mutation in the NUDT15 gene (a gene that is involved in the breakdown of Azathioprine 1A Farma in your body), then the risk of you getting infection and hair loss is higher and the doctor can give you a lower dose in this case. .
