When a person has got an autoimmune disease, then his immune system mistakes healthy cells and tissues for some foreign invaders, like germs. Essentially, his immune system turns against his body before attacking it. Based on the part of your body that is being attacked, this response does result in various kinds of autoimmune diseases. An immunosuppressant holds back a person’s immune system and helps in preventing inflammation and cell damage. These drugs also remain helpful for lessening symptoms. The immunosuppressants are also capable of putting autoimmune diseases into remission. You might need immunosuppressants when you have got an autoimmune disease like:Multiple sclerosisAlopecia areataInflammatory bowel diseaseRheumatoid arthritisLupus
