Abrammune is an immunosuppressive drug used to treat some chronic diseases related to an overactive immune system, such as rheumatoid arthritis and some blood disorders. The drug works by reducing the production of immune cells that attack the body's tissues incorrectly, which helps reduce inflammation and control symptoms. It is taken orally in a dose determined according to the doctor's diagnosis and the patient's response. Periodic tests must be performed to monitor the number of blood cells and liver function, as Abrammune may cause a decrease in immunity or changes in vital tests. It is also necessary to monitor any signs of infection and avoid sources of infectious diseases during the treatment period. It is not recommended to use it during pregnancy or breastfeeding except under close medical supervision.
