Milk-alkali syndrome is now very uncommon because nonantacid treatments for indigestion, gastric ulcers, and peptic ulcer disease have replaced most excessive antacid use.
If you do use antacids often, don't drink large amounts of milk, and tell your doctor about your digestive problems. If you are trying to prevent osteoporosis, do not take more than 1.5 grams of calcium per day.
