How we grade severity & evidence

Severity levels

  • Contraindicated: These should generally not be used together.
  • Major: Potentially serious — often needs a change or close monitoring.
  • Moderate: Can be significant — usually manageable with monitoring.
  • Minor: Usually limited clinical impact.

Evidence grades

  • Established: Well documented — supported by controlled studies or strong clinical data.
  • Probable: Good supporting evidence, though not definitively proven.
  • Suspected: Some evidence suggests this interaction, but it is not well established.
  • Possible: Limited or conflicting evidence; the interaction may occur.
  • Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.

Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.

What happens

Acute renal failure

Interaction Deep Dive

Concomitant use of angiotensin-converting (ACE) inhibitors and cycloSPORINE may decrease renal function. Two reported cases involved renal transplant patients receiving enalapril concurrently with cycloSPORINE and furosemide. With discontinuation of the ACE inhibitor, renal function improved. The investigators speculated that long term administration of cycloSPORINE may cause renal hypoperfusion, which in turn may activate the renin-angiotensin system for maintenance of glomerular filtration. If these conditions are true, then the introduction of an ACE inhibitor could trigger an acute deterioration in renal function1.

Why it happens (mechanism)

Decreased angiotensin II
