Résumé

Activated charcoal adsorbs methotrexate in the gut and interrupts its enterohepatic circulation, decreasing exposure. This can reduce therapeutic effect with routine use but can help limit toxicity in overdose.

Ce que signifie cette interaction, en termes simples

Charcoal and Methotrexate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Charcoal belongs to Gastrointestinal Tract; Methotrexate belongs to Oncology.

Niveau de preuve: Moderate

Pourquoi elle survient

Charcoal binds methotrexate in the gastrointestinal lumen, reducing absorption and biliary reabsorption.

Conduite à tenir

Do not give charcoal with oral methotrexate therapy; separate doses by several hours if charcoal is needed. In toxicity, charcoal may be used alongside leucovorin and monitoring of methotrexate levels and renal function.
