Dexamethasone and Cyclosporine Interaction

Drug interaction information between Dexamethasone and Cyclosporine.

Dexamethasone and Cyclosporine have a documented minor interaction in FDA labeling.

FDA drug labeling documents a minor-severity interaction between Dexamethasone 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

Dexamethasone

Corticosteroid

Drug B

Cyclosporine

Calcineurin Inhibitor (Immunosuppressant)

How They Interact

These two drugs can make each other more powerful when taken at the same time. This increases the chance of having side effects from both medicines.

What To Do

Your doctor should watch you closely for side effects and may need to adjust your dosages.

FDA Label Information

Cyclosporine: Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently.

Why do Dexamethasone and Cyclosporine interact?

These two drugs can make each other more powerful when taken at the same time. This increases the chance of having side effects from both medicines.

Understanding the Dexamethasone and Cyclosporine Interaction

FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Dexamethasone belongs to the Corticosteroid 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: These two drugs can make each other more powerful when taken at the same time. 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. Dexamethasone has 21 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: Your doctor should watch you closely for side effects and may need to adjust your dosages. 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 Dexamethasone or Cyclosporine based on a web page, speak with your prescriber or pharmacist before making any change.
