moderate Known Drug Interaction

Cyclosporine Administration of non-steroidal anti-inflammatory drugs concomitantly with cyclosporine has been associated with an increase in cyclosporine-induced toxicity, possibly due to decreased synthesis of renal prostacyclin. NSAIDs should be used with caution in patients taking cyclosporine, and renal function should be carefully monitored.

How to Read This cyclosporine vs diflunisal Comparison

cyclosporine is classified in the Calcineurin Inhibitor (Immunosuppressant) drug class, while diflunisal sits within the Nonsteroidal Anti-Inflammatory Drug (NSAID) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, cyclosporine has 22,843 submissions while diflunisal has 265. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to diflunisal may reduce protective substances in the kidneys, which can increase the risk of harmful side effects from cyclosporine. this happens because the kidneys cannot process the drugs as safely.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
