Cyclosporine (Ciclosporin): A Patient Guide for Rheumatology Care
Also known as: Ciclosporin · Cyclosporin A · Neoral · Sandimmun
Cyclosporine, also spelled ciclosporin, is an immunosuppressant I use selectively rather than routinely. It can work quickly in the right situation, but it needs close attention to the kidneys, blood pressure and drug interactions. Whether it suits you depends on an individual assessment.
Calm, careful medication review by a consultant rheumatologist.
What this medicine is
Cyclosporine is a calcineurin inhibitor. It works by damping down a specific signalling pathway inside T lymphocytes, the immune cells that drive much of autoimmune inflammation. Because it targets that pathway rather than simply suppressing everything, it can be effective, but it also affects the small blood vessels in the kidneys and can raise blood pressure. It is taken by mouth as capsules or a liquid. Brands and formulations are not automatically interchangeable, so I keep patients on the same formulation unless there is a reason to change. Your prescriber sets the strength and schedule, which is why I do not publish dose schedules here.
Uses and context
In rheumatology and autoimmune care, cyclosporine may be considered in selected inflammatory rheumatic and autoimmune disease, including some cases of rheumatoid arthritis that have not responded to other conventional DMARDs, selected lupus manifestations, some inflammatory myositis, uveitis, Behcet's disease and severe plaque psoriasis. This list is not exhaustive, and cyclosporine is rarely a first choice. I usually reach for it when other options are unsuitable, have failed, or when a fast response matters and long-term use is not the plan.
How this relates to rheumatology care
Realistic benefit and timing: cyclosporine often works faster than methotrexate, with some improvement over four to eight weeks. I usually think of it as a medium-term medicine rather than something to stay on for many years, because the risk to the kidneys and blood pressure grows with duration and amount. My approach is to use the smallest amount that controls the disease, monitor closely, and plan what will take over from it. Because it is handled by the same liver enzymes as many other medicines, interactions are a genuine issue, and I always want the full list of what you take, including over-the-counter and traditional or herbal products. It is also worth knowing that this is an immunosuppressant, so infections need respect and prompt attention.

What safety checks may matter
Blood pressure and kidney function (creatinine, eGFR) before starting, then regularly, as directed by your clinician
Liver function tests, full blood count, potassium, magnesium, uric acid and lipids monitored as advised
Screening for infection, including hepatitis B and C and tuberculosis where relevant, before starting
A complete medicine list reviewed for interactions, including anti-inflammatories, some antibiotics and antifungals, statins, blood pressure medicines and herbal products
Skin checks and sun protection advice, particularly with previous phototherapy or long-term immunosuppression
Vaccination status reviewed before starting; non-live vaccines updated where possible
Cervical screening and other age-appropriate cancer screening kept up to date
Regular review of whether cyclosporine is still the best option or can be handed over to another medicine
Side effects and red flags
If you have emergency symptoms such as severe allergic reaction, breathing difficulty, chest pain, stroke-like symptoms, severe abdominal pain, vomiting blood, black stools, sudden vision loss, severe infection symptoms, or severe weakness or confusion, please seek urgent medical care first rather than waiting for a WhatsApp reply.
Fever, chills, a persistent cough, night sweats or any sign of serious infection
A marked fall in how much urine you pass, or new swelling of the legs and face
Severe headache, visual disturbance or a blood pressure reading much higher than usual
Confusion, seizures or new marked tremor and unsteadiness
Yellowing of the eyes or skin, or dark urine
Unusual bruising, bleeding, or a widespread rash
Signs of a severe allergic reaction such as facial or tongue swelling
Things worth knowing day to day
Avoid grapefruit and grapefruit juice, and pomelo. They raise cyclosporine levels in the blood and increase the risk of side effects.
Do not start any new medicine, supplement or herbal product without checking with me first, because interactions with cyclosporine are common and can be significant.
Avoid anti-inflammatory painkillers unless I have agreed to them, because they add to the strain on the kidneys.
Common effects include gum enlargement and tenderness, tremor, headache, increased hair growth on the body, tingling in the hands and feet, nausea and raised blood pressure. Good dental hygiene and regular dental cleaning help protect the gums.
Avoid live vaccines while on cyclosporine. Non-live vaccines such as influenza, COVID-19 and pneumococcal are encouraged, ideally before starting.
Protect your skin from the sun and report any new or changing skin lesion.
Tell any surgeon or dentist that you take an immunosuppressant before a procedure, and let me know so timing can be planned.
Cyclosporine needs specialist discussion in pregnancy, planned pregnancy and breastfeeding. It is one of the immunosuppressants that is sometimes continued in pregnancy under close supervision, but that decision is individual and must be made with me in advance, never on your own.
Take it consistently in relation to food and at similar times each day, and stay on the same brand or formulation unless I have changed it deliberately.
