It is true that kidney transplant recipients must take antirejection drugs throughout their lives. Organ transplants are lifesaving especially in end organ damage, but are prone to rejection by the body's immune system. The recipients are therefore advised to take immunosuppressive drugs to keep the body immune system from transplant attack that can lead to their  failure.

The body's immune system has a complex mechanism known as major histocompatibility class II ( MHC II) that detect transplant as foreign and pathogenic. This trigger immune attack through production of antibodies. The drugs include Tacrolimus, Cyclosporine and  Prednisone. They prevent transplant immune attacks ensuring long term viability. This is key to ensure patients lead near normal lives. There several adverse effects associated  with these drugs such as increased susceptibility to infections due to weakened immune system that must be accounted for.
