Azathioprine 50mg,Tablet belongs to a group of medicines called immunosuppressants. It is used with other medicines to prevent your body rejecting an organ (such as a kidney, heart or liver) after a transplant. It is also used in the treatment of rheumatoid arthritis. Tablet works by weakening the body’s immune system, so it does not attack the new organ. The amount of medicine to be taken and how often you need to take it will depend on the type of transplant you have. Follow your doctor’s instructions on this. You should take it along with food. Swallow it as a whole, do not crush, chew, break, or open them. Take the medicine regularly to get the most benefit and keep taking it even if you feel well. If you stop taking it, you may increase the chances of rejecting your transplanted organ. The treatment will continue for as long as you need it to prevent rejection. It has many potential side effects. The most common are loss of appetite, nausea, and increased risk of bleeding. Because it suppresses your immune system, you may catch more infections than usual. There’s also an increased risk of developing some cancers for this reason. To reduce your risk of skin cancer, limit your exposure to the sun.
