Acute Overdosage: Acute Overdosage with antacid may cause osmotic catharsis, leading to fluid and electrolyte losses. Hypermagnesemia and central nervous system depression may follow overdoses of magnesium-containing antacid.
Treatment: Specific treatment is rarely needed in either suicidal or non-suicidal patients. Gastrointestinal decontamination is not indicated unless toxic coingestants are suspected.
Hypermagnesemia may be treated with fluids and loop diuretics. Hemodialysis reduced plasma levels of magnesium.
Aluminium may be removed with deferoxamine followed by hemodialysis.
