Summary
Vitamin D and its analogues increase intestinal absorption of aluminum from aluminum-containing antacids. With long-term use, especially in renal impairment, aluminum may accumulate and cause bone disease, anemia or neurotoxicity.
What this interaction means in plain words
Aluminum hydroxide and Vitamin d can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Aluminum hydroxide belongs to Gastrointestinal Tract; Vitamin d belongs to Gastrointestinal Tract.
Why it happens
Vitamin D enhances intestinal absorption of aluminum, and impaired renal excretion allows tissue accumulation.
What to do
Avoid chronic aluminum antacids in patients taking vitamin D, particularly with chronic kidney disease. Use a non-aluminum alternative and monitor serum aluminum if exposure is unavoidable.
