What is Cyclosporine: Uses, Warnings & Interactions

Updated May 14, 2025  •  Published Dec 30, 2020

Cyclosporine is an oral or topical immune suppressant used in people with inflammatory conditions, organ transplants, or eye problems. It comes in two different forms: cyclosporine and cyclosporine modified. The second is absorbed better and more predictably when taken orally, so it can treat more health conditions reliably than cyclosporine non-modified. Nearly all oral forms of cyclosporine, except brand-name Sandimmune, contain cyclosporine modified as the active ingredient. With a variety of uses, cyclosporine comes in a variety of dosage forms, including capsules, oral solution, injections, and eye drops.

What is Cyclosporine used for?

Oral cyclosporine (modified or unmodified) blocks immune system activity to prevent rejection of a transplanted organ. Modified cyclosporine can also be prescribed to block the immune system to reduce the symptoms of severe rheumatoid arthritis or severe or untreatable plaque psoriasis. Cyclosporine eye drops (solution or emulsion) usually contain unmodified cyclosporine and are FDA-approved to treat chronic dry eyes. Verkazia cyclosporine eye drops are used to relieve the eye symptoms of seasonal allergies (vernal keratoconjunctivitis).
