Myfortic, with the active ingredient mycophenolic acid, is a medication primarily used as an immunosuppressant. It is specifically designed to prevent organ rejection in patients who have undergone kidney transplants. Myfortic works by inhibiting the production of DNA in certain immune cells, thereby reducing the activity of the immune system and minimizing the risk of organ rejection. This medication is part of a class of drugs known as immunosuppressive agents and is often used in combination with other medications to achieve optimal results in transplant patients. It is crucial for patients taking Myfortic to follow their healthcare provider's instructions closely, as the balance of suppressing the immune system enough to prevent rejection, but not so much as to increase the risk of infection, is delicate.
