Take magnesium oxide exactly as directed by your doctor or as directed on the package. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you. Take the tablets and capsules with a full glass of water. To ensure that you get the correct dose, measure the liquid form of magnesium with a dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.
