Azathioprine is a medication that is commonly used to suppress the immune system in order to prevent rejection of transplanted organs or to treat certain autoimmune diseases. It works by inhibiting the production of DNA and RNA, which helps to reduce the activity of immune cells. Azathioprine is available in tablet form and is typically taken once or twice daily, as prescribed by a healthcare professional. It is important to follow the dosage instructions and regularly monitor blood counts while taking this medication. Common side effects may include nausea, vomiting, and a decreased ability to fight infections.
