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.

Of 135 documented Acarbose interactions, 70 are rated major — including this one.

The Bottom Line
Both drugs can stress the liver, so using them together may raise the risk of liver injury; keep taking both as prescribed and ask your prescriber whether the combination is right for you and if liver monitoring is needed.

Both of these medicines can be tough on your liver. Levoketoconazole (Recorlev) is used to treat Cushing's syndrome, and it carries a known risk of liver injury. Acarbose (Precose), which helps control blood sugar, has also been linked to liver problems in some people. Taking them together may add up and raise the chance of harm to your liver.

This concern is based on how these drugs are known to behave rather than on strong studies of the two together. The good news is that your care team can manage this. They may watch your liver with blood tests and decide the safest plan for you, so please don't change anything on your own. Just talk with your pharmacist or doctor.

Concern: Additive risk of hepatotoxicity and drug-induced liver injury when combining levoketoconazole with another agent carrying hepatotoxic potential (acarbose has documented, though uncommon, hepatic adverse effects).

  • Mechanism: Unknown; presumed additive hepatocellular injury rather than a defined PK interaction. Neither is a prodrug relevant here.
  • Direction: Increased cumulative hepatotoxic risk.
  • Evidence: Theoretical.
  • Onset: Unspecified.
  • Management: The labeling advises avoiding levoketoconazole with hepatotoxic drugs. If used together, monitor LFTs (ALT, AST, bilirubin) at baseline and periodically; individualize therapy and consider alternatives.
