Summary

Sucralfate contains aluminum, and vitamin D may increase aluminum absorption from the gut. With prolonged use, particularly in renal impairment, aluminum can accumulate and cause toxicity affecting bone and the nervous system.

What this interaction means in plain words

Cholecalciferol and Sucralfate 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.

Cholecalciferol belongs to Musculoskeletal; Sucralfate belongs to Gastrointestinal Tract.

Evidence level: Low

Why it happens

Vitamin D enhances intestinal absorption of aluminum, and aluminum is poorly excreted when renal function is reduced.

What to do

Avoid long-term combined use in patients with renal impairment and consider an alternative to sucralfate. If it is used, keep courses short.
