Major Pharmaceuticals Milk of Magnesia is an institutional-grade oral saline laxative and antacid suspension engineered specifically for healthcare facilities, hospital inpatient units, long-term care environments, and outpatient clinical settings. Containing Magnesium Hydroxide (400 mg per 5 mL), this classic osmotic formulation works by drawing water into the intestinal lumen to stimulate peristalsis and promote gentle, predictable bowel evacuation, typically within 0.5 to 6 hours. Additionally, it functions as an effective antacid by neutralizing excess gastric acid in the stomach. Delivered in a palatable original unflavored suspension packaged in a high-yield 16 oz (473 mL) bottle, this liquid format is ideal for patients requiring acute constipation management or acid indigestion relief without harsh stimulant effects. Standardized National Drug Codes (NDC) enable precise barcode verification and institutional inventory control.
