Cyclosporine can treat conditions including rheumatoid arthritis, unresponsive psoriasis, and eczema. Additionally, the drug is often used in combination with other medications, like steroids or other immunosuppressants, to stop the body from rejecting an organ transplant.1 (The medication is specifically used for people who have received liver, heart, or kidney transplants.)
Less commonly, cyclosporine is sometimes used to treat amyotrophic lateral sclerosis (or ALS), nephrotic syndrome, graft vs. host disease, ulcerative colitis, among other conditions.7
When it is put in the form of eye drops, cyclosporine can treat various eye conditions, like dry eye disease, allergic conjunctivitis, and keratoconjunctivitis, or inflammation of the cornea. 7
