Milk Of Magnesia (Magnesium Hydroxide)

Magnesium hydroxide, the active ingredient in Milk of Magnesia, is an antacid presented as an oral suspension for oral use. It provides relief of occasional constipation and treats heartburn and dyspepsia in adults and children.

GNH USA supplies Milk of Magnesia as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Milk of Magnesia (magnesium hydroxide) is used to manage conditions related to excess gastric acidity and reduced intestinal motility. - Heartburn: neutralizes stomach acid to relieve burning sensation. - Dyspepsia: reduces gastric discomfort and bloating associated with indigestion. - Occasional constipation: draws water into the intestine to soften stool and promote bowel movements. - Acid reflux: alleviates symptoms by decreasing gastric acidity.

Magnesium hydroxide may cause a range of adverse reactions, most of which are mild and transient. Common Side Effects: - Diarrhea: loose stools due to increased intestinal water. - Abdominal cramping: mild stomach discomfort. - Nausea: feeling of sickness. - Flatulence: increased gas production. - Electrolyte imbalance: mild changes in serum magnesium. Serious or Rare Side Effects: - Hypermagnesemia: elevated magnesium levels, especially in renal impairment. - Severe dehydration: excessive fluid loss from prolonged diarrhea. - Allergic reaction: rash, itching, or swelling. - Electrolyte disturbances: significant shifts in potassium or calcium.

When using Milk of Magnesia, certain precautions should be observed to minimize risks. - Assess renal function: avoid use in severe renal impairment. - Monitor electrolyte status: watch for magnesium excess in patients on other magnesium‑containing products. - Use with caution in elderly: increased susceptibility to dehydration. - Avoid prolonged use: chronic use may lead to dependence for bowel movements. - Pregnancy and lactation: safety not established; consult healthcare professional. - Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Magnesium hydroxide can interact with other medicines, altering their absorption or effect. Major Interactions (Avoid): - Tetracycline antibiotics: reduced absorption, may decrease efficacy. - Bisphosphonates: chelation reduces drug bioavailability. - Iron supplements: magnesium binds iron, lowering iron absorption. Moderate Interactions (Monitor Closely): - Digoxin: increased serum levels due to electrolyte shifts. - Potassium‑sparing diuretics: risk of hypermagnesemia. - Levothyroxine: may impair absorption, separate dosing by at least 4 hours.
