What is Magnesium Hydroxide?

Magnesium is a natural mineral. Magnesium hydroxide decreases stomach acid and increases the amount of water in the intestines, which may induce bowel movements. Magnesium hydroxide is used as a laxative to relieve occasional constipation and as an antacid to relieve indigestion, stomach acid, and heartburn.

Uses of Magnesium Hydroxide

Magnesium hydroxide is primarily used for:

  • Occasional constipation: It helps to make bowel movements easier by bringing water into the intestines.
  • Heartburn, upset stomach, or indigestion: It works like an antacid, reducing stomach acid to ease discomfort.
  • Magnesium deficiency: It helps treat and prevent low magnesium levels caused by different health issues. Magnesium deficiency usually occurs when people have
    • Liver disorders
    • Heart failure
    • Vomiting or diarrhoea
    • Kidney dysfunction
    • other conditions
  • High blood pressure in pregnancy: It’s given through a vein to lower high blood pressure (pre-eclampsia) during pregnancy and prevent seizures.

How to use Magnesium Hydroxide Suspension?

  • Take it by mouth as instructed. If it’s chewable, chew it thoroughly before swallowing. For the liquid form, shake the bottle well before each dose.
  • Use a special measuring device or spoon to carefully measure your dose. Avoid using a regular household spoon, as it may not give the correct dose.
  • If you’re using it for constipation, drink a full glass of water (8 ounces or 240 milliliters) with each dose.
  • Follow all the directions on the product package or as directed by your doctor.

Remember:

  • Using it for a long time or too frequently for constipation may lead to reliance on laxatives and ongoing constipation.
  • Overuse can cause persistent diarrhea, dehydration, and mineral imbalance.
  • If your condition persists or worsens, inform your doctor. Bowel movements may take between 30 minutes and 6 hours to relieve constipation.
  • Don’t use this or other laxatives regularly for more than a week without consulting your doctor.
  • If you have stomach acid issues, don’t take the maximum dose for more than two weeks unless directed by your doctor.

  • Let your doctor know about all prescription and over-the-counter medications, vitamins, supplements, and herbal products you’re taking or plan to take. They may need to adjust your doses or monitor you for side effects.
  • If you’re taking other medications, take them at least 2 hours before or after taking magnesium hydroxide.
