  • Maalox (aluminum / magnesium / simethicone) contains aluminum and magnesium that can build up in your kidneys if you have kidney problems which can be dangerous. Talk to your doctor or pharmacist before taking Maalox (aluminum / magnesium / simethicone) to see if it is right for you. Don't take more than the maximum amount per day as shown on the label.
  • If you have kidney or hyperparathyroid disease Rolaids (Calcium Carbonate / Magnesium Hydroxide) can build up in your blood. This may can cause toxic levels of calcium in your body. This is more likely if you have severe kidney disease (defined as a kidney function blood test called GFR of less than 30ml/min). If you have severe kidney disease or are on kidney dialysis don't use Rolaids (Calcium Carbonate / Magnesium Hydroxide); a different antacid would be better for you.
  • Rolaids (Calcium Carbonate / Magnesium Hydroxide) contains calcium. Calcium can be an ingredient in some kidney stones.

Use the lowest dose for the shortest time possible or just play it safe and use a different antacid instead.
  • People with kidney disease on dialysis may need to take a lower dose or avoid use. Your doctor can do blood tests to see if it's safe to use.
