Azathioprine
About Azathioprine
Azathioprine is used to reduce the pain/inflammation in rheumatoid arthritis conditions and keep the immune system from attacking new transplant organs like kidneys. Besides this, it also treats pain and inflammation in gastrointestinal issues like Crohn's disease and ulcerative colitis for patients who have undergone a kidney transplant.
Azathioprine contains 'Azathioprine' that works by reducing the function of the cells, causing inflammation, especially in the joint tissues, thereby decreasing pain and inflammation and slowing down the joint damage and disease progression over time. Besides this, after an organ transplant, your body will try to attack the new organ as it sees it as foreign. Azathioprine helps stop your body from rejecting a new organ by suppressing your immune system.
In some cases, you may experience certain common side effects such as nausea, headaches, vomiting, diarrhoea, unusual fatigue, dizziness, loss of appetite, increased liver enzymes, lowered resistance to infections, tingling sensation, stomach pain, leukopenia (decreased number of white blood cells), and sore throat. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.
Take Azathioprine as prescribed. Your doctor will advise you on how often you should take Azathioprine based on your medical condition. Azathioprine can be taken with or without food. Do not crush, chew, or break it.
Do not take Azathioprine if you are pregnant or planning a pregnancy. Azathioprine should not be taken by breastfeeding mothers as it passes into breast milk. Azathioprine should not be given to children as safety and efficacy have not been established. Inform your doctor about your health condition and medicines to rule out any unpleasant side effects.

Patients Concern
Disease/Condition Glossary
Rheumatoid arthritis: It is an autoimmune disease (the body's immune system attacks its tissue) that leads to joint pain and damage. Symptoms of rheumatoid arthritis include pain, inflammation of joints, difficulty moving, and swelling.
Kidney transplant rejection: When you get a new kidney transplanted to your body, your body recognises it as a foreign element and tries to attack, and reject it because it is not originally part of your body. So, immunosuppressant drugs like Azathioprine are given to such patients to suppress their immune system from attacking a newly transplanted kidney. The ultimate goal is to adjust immunosuppressants to prevent rejection and minimise any side effects of the drugs.
