Greens Milk of Magnesia

Who is this for?

Magnesium hydroxide is a gentle antacid and laxative that works by neutralizing excess stomach acid and drawing water into the intestines to help soften stool and make bowel movements easier.

Neutralizes gastric acid by reacting with hydrochloric acid to form magnesium chloride and water, raising intragastric pH and relieving acidic symptoms. Additionally, osmotically draws water into the intestinal lumen, increasing stool bulk and promoting peristalsis to relieve constipation.

Is Magnesium safe to take with another drug?

For constipation: Take 2 to 4 tablespoons (30–60 mL) of the liquid (like Greens Milk of Magnesia) at bedtime with a full glass of water. For stomach acid or heartburn: Take 1 to 3 teaspoons (5–15 mL) up to 4 times a day, preferably between meals and at bedtime. Shake the bottle well before use.

Magnesium hydroxide is usually taken only when needed, so there is no strict dosing schedule. If you are using it regularly and you miss a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed one — do not double up.

• Loose or watery stool (diarrhea)
• stomach cramps
• nausea
• feeling bloated or gassy

Magnesium hydroxide can reduce the effectiveness of antibiotics like tetracycline and ciprofloxacin — take them at least 2 hours apart. It can also interfere with iron supplements and some blood pressure drugs, so space them out. Alcohol can worsen stomach irritation, so it is best to avoid it.

Store at room temperature in a cool, dry place away from direct sunlight and heat. Keep the bottle tightly closed to prevent contamination. Always keep it out of the reach of children.
