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

Inflammation of intestinal mucosa, liver, spleen, and lymph nodes

Interaction Deep Dive

Docusate may facilitate absorption or hepatic cell uptake of mineral oil (liquid paraffin)2345. Docusate salts, extensively used as stool softeners, include docusate sodium (dioctyl sodium sulfosuccinate), docusate calcium (dioctyl calcium sulfosuccinate), and docusate potassium (dioctyl potassium sulfosuccinate). Docusate should not be administered along with mineral oil unless directed by a physician 6.

Why it happens (mechanism)

Enhanced mineral oil absorption

Literature reports

1 report — tap to read

a) Oral administration of docusate salts with mineral oil is not recommended due to the possibility of increased absorption of mineral oil. Mineral oil absorption has occurred following oral ingestion: detectable concentrations of mineral oil have been demonstrated in the lymph nodes, intestinal mucosa, liver, and spleen. Chronic inflammation of cells as in a foreign-body reaction has been seen at these sites. Additionally hepatic infiltrates have resulted from mineral oil absorption 1.
