Magnesium gluconate is used to treat low blood magnesium. Low blood magnesium is caused by gastrointestinal disorders, prolonged vomiting or diarrhea, kidney disease, or certain other conditions. Certain drugs lower magnesium levels as well.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Magnesium gluconate comes as a tablet and liquid to take by mouth. It usually is taken two to four times a day, depending on your condition. Follow the directions on your prescription label or package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take magnesium gluconate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
To prevent side effects, magnesium gluconate should be taken with meals. If you are taking an extended-release (long-acting) product, do not chew or crush the tablet. There are some tablets that can be crushed and mixed with food.
A balanced diet usually provides enough magnesium. Sometimes supplements are necessary because of illness or medication use. Magnesium is found in a variety of foods, including green leafy vegetables, nuts, peas, beans, and cereal grains with the outer layers intact.
A high-fat diet may decrease the amount of magnesium you absorb from your diet. Over-cooking food also may decrease the amount of magnesium you absorb from your food. Follow the diet recommended by your doctor or dietitian. Ask if you are not sure you are getting enough vitamins and minerals.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
