SIDE EFFECTS OF ANTACIDS Antacids may cause dose-dependent rebound hyperacidity and milk-alkali syndrome. Antacids that contain aluminum hydroxide may cause constipation, aluminum-intoxication, osteomalacia, and hypophosphatemia.Antacids that contain magnesium have a laxative  effect that may cause diarrhoea Brands with magnesium may cause diarrhea. Brands with calcium or aluminum may cause constipation. Rarely, brands with calcium may cause kidney stones or other problems. If you take large amounts of antacids that contain aluminum, you may be at risk for calcium loss, which can lead to weak bones.
