What Aluminum hydroxide is used for

  • Heartburn and acid indigestion
  • Binding phosphate in chronic kidney disease (limited, specialist-led use)

◆ Kidney note

Aluminum can accumulate dangerously when the kidneys fail, so binder use in dialysis is specialist-guided and usually time-limited.

Common side effects

  • Constipation
  • Loss of appetite
  • Nausea

Important cautions

  • It blocks absorption of several medicines — separate the timing
  • Long-term use in kidney failure can let aluminum build up in bones and the brain — it is used only briefly and carefully in dialysis patients
