How Much Milk of Magnesia to Take?
The appropriate dosage of Milk of Magnesia depends on the intended use and age. For adults, the typical dose for constipation relief is 2 to 4 tablespoons (30-60 mL), while children typically require a lower dose that should be determined by a pediatrician or pharmacist.
Introduction: Understanding Milk of Magnesia
Milk of Magnesia is a commonly used over-the-counter medication primarily used as a laxative and antacid. Its active ingredient, magnesium hydroxide, works by drawing water into the intestines, softening stool and easing bowel movements. As an antacid, it neutralizes stomach acid, providing relief from heartburn and indigestion. While readily available and generally safe when used as directed, understanding the correct dosage is crucial for effective treatment and to avoid potential side effects. It’s important to consult with a healthcare professional, especially for children, those with kidney issues, or individuals taking other medications.

Alternatives to Milk of Magnesia

Understanding the Science Behind Milk of Magnesia
Magnesium hydroxide, the active ingredient, is a base that neutralizes stomach acid, relieving heartburn. As a laxative, it’s an osmotic agent; it draws water into the intestines, increasing stool volume and stimulating bowel movements. This process helps to soften the stool, making it easier to pass. The increased water content also helps to lubricate the intestinal walls, further facilitating movement.
