Azathiol 50mg Tablet is an immunosuppressant medication used to prevent organ rejection after transplants and rheumatoid arthritis treatment. It weakens the body's immune system, preventing it from attacking the new organ. The dosage depends on the transplant type and should be taken regularly. Side effects include loss of appetite, nausea, increased bleeding risk, and increased infection risk. Azathiol can cause birth defects and miscarriages, so it's not recommended for pregnant, planning to become pregnant, or breastfeeding individuals. It's important to consult a doctor about any infection or bleeding signs.
