Ciclosporin is a disease-controlling treatment: it suppresses the immune activity driving inflammation, protecting joints and organs. It works over weeks, not days, and is not a painkiller. Its benefit holds only while blood levels stay in range — which is why dosing and monitoring are so closely paired with this medicine.
What it is: A disease-modifying anti-rheumatic drug (DMARD) that regulates an overactive immune system to limit autoimmune progress and joint damage. It is prescribed for rheumatoid arthritis pain, swelling and stiffness, psoriatic arthritis, and SLE. It is not a painkiller; it is a long-term treatment — benefits may take up to four months. Keep taking it even if it is slow to work, and even when you improve.
May not be suitable if: you have kidney problems, uncontrolled high blood pressure, gout or high urate, or a history of cancer. A blood pressure check plus blood and urine tests are done before starting.
How it's taken: Capsules twice daily (it is also available as a liquid). You start low; the dose is based on body weight and kidney function.
Side effects: Raised blood pressure, kidney effects, and raised lipids (cholesterol). Regular blood tests and frequent blood-pressure checks are required — you must not take ciclosporin unless you're having regular checks. Stay on the same brand if possible, as different brands absorb differently. Report nausea, diarrhoea, headache, gum overgrowth, tiredness, excess hair growth, or any new concerning symptoms; stop and see a doctor immediately if severe. Chickenpox and shingles can be severe and may need antivirals and pausing treatment. Grapefruit and grapefruit juice increase ciclosporin levels and side-effect risk — avoid them.
Interactions: Discuss all new medicines with your doctor. Take NSAIDs only on GP or rheumatologist advice, and don't take over-the-counter or herbal remedies without discussing them first.
Pregnancy: Current guidelines say it can be taken during pregnancy — discuss with your doctor if you are planning a family or are pregnant. It may pass into breast milk but is barely detectable in babies, so it is unlikely to be harmful; discuss with your doctor whether to take it while breastfeeding.
Why the checks: The close monitoring is built around how this drug behaves: blood-pressure readings and kidney blood tests track its two main silent effects; drug-level checks confirm the dose is in the effective-but-safe window; and cholesterol and potassium are watched because ciclosporin can move both. Every test answers a specific question about a medicine that needs steering.

Common worries
Why so many blood-pressure and kidney checks?
Ciclosporin can raise blood pressure and strain the kidneys, silently. Regular checks catch either trend while it is small and reversible — this monitoring is precisely what makes the drug usable safely.
Why do I keep hearing about grapefruit?
Grapefruit blocks the enzyme that clears ciclosporin, so levels climb unpredictably. Many medicines interact the same way, which is why every new prescription — from any clinician — needs a quick check with us.
Will the extra hair growth / gum swelling happen to me?
Both are recognised effects of ciclosporin and vary widely between people. Good dental hygiene helps the gums; report changes and we will judge together whether they are acceptable or the plan should change.
