Magnesium hydroxide is an inorganic compound with the chemical formula Mg(OH)₂. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water. Magnesium hydroxide is a common component of antacids, such as milk of magnesia. \n \nMagnesium hydroxide is used to treat occasional constipation in children and adults on a short-term basis. Magnesium hydroxide is in a class of medications called saline laxatives. It works by causing water to be retained in the stool. \n \n \n \nMagnesium hydroxide is an inorganic compound with the formula Mg(OH)2\text{Mg(OH)}_2Mg(OH)2​. It appears as a white, odorless powder or a colorless, crystalline solid. Here are some key points about magnesium hydroxide: \n

Properties of Magnesium Hydroxide

\n

Benefits of Magnesium Hydroxide

\n

\n
• Gentle on the Stomach: Unlike some stronger antacids, magnesium hydroxide is less likely to cause gas and bloating.
\n
• Dual Functionality: Provides both antacid and laxative effects, making it versatile in treating gastrointestinal issues.
\n

\n

Precautions

\n

\n
• Dosage: Overconsumption can lead to side effects such as diarrhea and abdominal cramping.
\n
• Interactions: May interact with other medications; it’s advisable to consult a healthcare provider if taking other treatments.
\n
• Chronic Use: Prolonged use can lead to electrolyte imbalances, particularly in individuals with kidney issues.
