Ciclosporin is an immunosuppressant, a drug that suppresses the body’s natural defences against infection and foreign cells. This action is of particular use following organ transplants, when the recipient’s immune system may reject the transplanted organ unless the immune system is controlled.
Ciclosporin is widely used after many types of transplant, such as heart, bone marrow, kidney, liver, and pancreas; its use has considerably reduced the risk of rejection. It is sometimes used to treat rheumatoid arthritis, some severe types of dermatitis, severe psoriasis, and a number of other autoimmune conditions.
Because ciclosporin reduces the immune system’s effectiveness, people being treated with it are more susceptible than usual to infections. Ciclosporin can also cause kidney damage.
Different brands of ciclosporin may reach different levels in your blood. It is important to know which brand you are taking. Do not try to make dose changes on your own.

General note Ciclosporin may interact with a large number of drugs. Check with your doctor or pharmacist before taking any new prescription or over-the-counter medications. Grapefruit juice can increase blood levels of ciclosporin. Avoid all grapefruit flesh and juice while taking ciclosporin. St John’s wort can reduce ciclosporin levels and even precipitate rejection of a transplanted organ. Avoid St John’s wort completely while taking ciclosporin.
Ciclosporin is prescribed only under close medical supervision, taking account of your condition and medical history.

Monitoring Regular blood tests should be carried out as well as tests for liver and kidney function. Ciclosporin blood levels should also be checked regularly.
