Vitamin D × Digoxin

MODERATE INTERACTION — Probable Evidence

⚠️ Mechanism

Vitamin D promotes calcium absorption. Hypercalcemia potentiates digoxin toxicity.

📋 Effect

Increased risk of digoxin toxicity if hypercalcemia develops

💊 Management

Monitor serum calcium and digoxin levels. Avoid excessive vitamin D dosing.

Plain Language Summary

This combination carries a moderate risk. Vitamin D helps your body absorb more calcium, and if calcium levels become too high, it can increase the risk of digoxin toxicity.
