Repaglinide and Cyclosporine Interaction

Drug interaction information between Repaglinide and Cyclosporine.

Repaglinide and Cyclosporine have a documented moderate interaction in FDA labeling.

FDA drug labeling documents a moderate-severity interaction between Repaglinide and Cyclosporine. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.

Drug A

Repaglinide

Meglitinide

Drug B

Cyclosporine

Calcineurin Inhibitor (Immunosuppressant)

How They Interact

Cyclosporine causes the amount of repaglinide in your blood to increase, which can make your blood sugar drop too low.

What To Do

Limit your total daily dose of repaglinide to 6 mg and check your blood sugar more frequently.

FDA Label Information

Cyclosporine Clinical Impact: Cyclosporine increased low dose repaglinide exposures by 2.5 fold [see Clinical Pharmacology (12.3) ] Intervention: Daily maximum repaglinide dose should be limited to 6 mg, and increased frequency of glucose monitoring may be required when repaglinide is co-administered with cyclosporine. Examples: beta-blockers, clonidine, guanethidine, and reserpine Clopidogrel : Avoid concomitant use; if used concomitantly initiate at 0.5 mg before each meal and limit total daily dose to 4 mg (7) Cyclosporine : Limit daily dose of repaglinide to 6 mg and increase frequency...

Frequently Asked Questions

Can I take Repaglinide and Cyclosporine together?

This is a moderate interaction. Limit your total daily dose of repaglinide to 6 mg and check your blood sugar more frequently.

How serious is the interaction between Repaglinide and Cyclosporine?

Why do Repaglinide and Cyclosporine interact?

Cyclosporine causes the amount of repaglinide in your blood to increase, which can make your blood sugar drop too low.

Understanding the Repaglinide and Cyclosporine Interaction

FDA-approved prescribing information for these two drugs flags their combination as a moderate-severity interaction. Repaglinide belongs to the Meglitinide class and Cyclosporine belongs to the Calcineurin Inhibitor (Immunosuppressant) class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Cyclosporine causes the amount of repaglinide in your blood to increase, which can make your blood sugar drop too low. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.

Context around a specific patient determines real-world impact. Repaglinide has 22 total documented interactions on file in this dataset, and Cyclosporine has 89. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Limit your total daily dose of repaglinide to 6 mg and check your blood sugar more frequently. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.

An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Repaglinide or Cyclosporine based on a web page, speak with your prescriber or pharmacist before making any change.
