This grade answers one narrow question: how strong is the public evidence and safety record behind this drug, and how clean is its money trail and court record? It is not a verdict on whether the drug is right for you.

FDA boxed warning

WARNING Only physicians experienced in management of systemic immunosuppressive therapy for the indicated disease should prescribe cyclosporine [MODIFIED]. At doses used in solid organ transplantation, only physicians experienced in immunosuppressive therapy and management of organ transplant recipients should prescribe cyclosporine [MODIFIED]. Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient. Cyclosporine [MODIFIED], a systemic immunosuppressant, may increase the susceptibility to infection and the development of neoplasia. In kidney, liver, and heart transplant patients, cyclosporine [MODIFIED] may be administered with other immunosuppressive agents. Increased susceptibility to infection and the possible development of lymphoma and other neoplasms may result from the increase in the degree of immunosuppression in transplant patients. Cyclosporine capsules [MODIFIED] and cyclosporine oral solution [MODIFIED] have increased bioavailability in comparison to Sandimmune® ...

What the FDA label says

Approved uses

INDICATIONS AND USAGE Kidney, Liver, and Heart Transplantation Cyclosporine capsules, USP [MODIFIED] and cyclosporine oral solution, USP [MODIFIED] are indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants. Cyclosporine capsules, USP [MODIFIED] and cyclosporine oral solution, USP [MODIFIED] have been used in combination with azathioprine and corticosteroids. Rheumatoid Arthritis Cyclosporine capsules, USP [MODIFIED] and cyclosporine oral solution, USP [MODIFIED] are indicated for the treatment of patients with severe active, rheumatoid arthritis where the disease has not adequately responded to methotrexate. Cyclosporine capsules, USP [MODIFIED] and cyclosporine oral solution, USP [MODIFIED] can be used in combination with methotrexate in rheumatoid arthritis patients who do not respond adequately to methotrexate alone. Psoriasis Cyclosporine capsules, USP [MODIFIED] and cyclosporine oral solution, USP [MODIFIED] are indicated for the treatment of adult, nonimmunocompromised patients with severe (i.e., extensive and/or disabling), recalcitrant, plaque psoriasis who have failed to respond to at least one systemic therapy (e.g., PUVA, ret...

Contraindications

CONTRAINDICATIONS General Cyclosporine [MODIFIED] is contraindicated in patients with a hypersensitivity to cyclosporine or to any of the ingredients of the formulation. Rheumatoid Arthritis Rheumatoid arthritis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive cyclosporine [MODIFIED]. Psoriasis Psoriasis patients who are treated with cyclosporine [MODIFIED] should not receive concomitant PUVA or UVB therapy, methotrexate or other immunosuppressive agents, coal tar or radiation therapy. Psoriasis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive cyclosporine [MODIFIED].

Warnings and precautions

WARNINGS (See also Boxed WARNING ) All Patients Cyclosporine, the active ingredient in cyclosporine capsules [MODIFIED] and cyclosporine oral solution [MODIFIED], can cause nephrotoxicity and hepatotoxicity. The risk increases with increasing doses of cyclosporine. Renal dysfunction including structural kidney damage is a potential consequence of cyclosporine [MODIFIED] and therefore renal function must be monitored during therapy. Care should be taken in using cyclosporine with nephrotoxic drugs . (See PRECAUTIONS ) Patients receiving cyclosporine [MODIFIED] require frequent monitoring of serum creatinine. (See Special Monitoring under DOSAGE AND ADMINISTRATION ) Elderly patients should be monitored with particular care, since decreases in renal function also occur with age. If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can be associated with the occurrence of structural kidney damage and persistent renal dysfunction. An increase in serum creatinine and BUN may occur during cyclosporine [MODIFIED] therapy and reflect a reduction in the glomerular filtration rate. Impaired renal function at any time requires close monitoring, and f...

Adverse reactions (label)

ADVERSE REACTIONS Kidney, Liver, and Heart Transplantation The principal adverse reactions of cyclosporine therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia. Hypertension Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients. Glomerular Capillary Thrombosis Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure. The pathologic changes resembled those seen in the hemolytic-uremic syndrome and included thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function. Similar findings have been observed when other immunosuppressives have been employed post-transplantation. Hypomagnesemia Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy. Although magnesium depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple fa...

Side-effect reports sent to the FDA

These are counts of reports people filed, not rates of harm. Anyone can file one, and nobody checks whether the drug was the cause. Millions of doses are taken for every report sent, so the useful part is how this drug compares with the average across all drugs.

109,336reports that mention this drug
108,915of those blame this drug, not another one the person was taking
68%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
11.9%of reports include a death, from any cause (average for all drugs: 9.1%)

12,045 reports blaming this drug for every million Medicare prescriptions filled, which is 4.4× the typical drug on this site. (27,604 reports in 2024–2026, against 2,291,687 Medicare fills in one year. This is the one number here that accounts for how many people take the drug.)

Source: the FDA's Adverse Event Reporting System (FAERS). Reports are voluntary and unverified. Drugs that are prescribed a lot, in the news, or in lawsuits attract more reports, so the percentages are compared with the whole database to correct for that partly, not fully.

Independent Cochrane reviews

Counts measure how much evidence exists and how transparent it is, not how big the benefit is. For that, ask your prescriber: if 100 people like me took this, how many would get better because of it, and how many would be harmed? (Doctors call these the "number needed to treat" and "number needed to harm.") It differs by condition and is the number drug ads leave out. Sources: PubMed, ClinicalTrials.gov.

Same ATC pharmacological class, graded ones first, best grade at the top. Being in the same class does not make them interchangeable for your condition; it makes them worth asking about.

Questions to ask your prescriber

  1. This drug carries a boxed warning. Which specific risk does it cover, and does it apply to me?
  2. The most-reported problems in FDA's adverse event data are eye irritation, product use in unapproved indication. How would we recognize and handle those?
  3. Off-label use is among the most-reported items for this drug. Is my use on-label, and if not, what evidence supports it?
  4. Why this one over tacrolimus, voclosporin? What would make you pick one of those instead?
  5. The manufacturer pays physicians heavily to promote this drug. Have you received anything from them?
  6. What result are we expecting, by when, and what is the plan if it does not happen?
  7. If 100 people like me took this drug, how many would actually get better because of it, and how many would be harmed by it? (Doctors call these the number needed to treat and the number needed to harm.)
