Magnesium Hydroxide

Magnesium Hydroxide

Magnesium hydroxide is useful for treating symptoms due to excess stomach acid, such as stomach pain, indigestion, or heartburn . Magnesium hydroxide is also used as a short-term treatment for constipation.

Magnesium hydroxide is an antacid that works by neutralizing and reducing stomach acid. This drug is also a laxative (laxative) which is thought to work by drawing water into the intestine and helping the large intestine move to expel feces.
