Magnesia (Magnesium Hydroxide)

Magnesium hydroxide acts as a base that reacts with gastric hydrochloric acid, forming magnesium chloride and water. This chemical reaction raises the pH of stomach contents, reducing acidity and alleviating discomfort. In the colon, the compound remains largely unabsorbed, drawing water into the lumen and facilitating stool softening and transit.

The appropriate dose of Magnesia is individualized and set by a prescriber based on the patient’s age, severity of symptoms, and overall health status. Because dosing can vary widely—from occasional heartburn relief to treatment of constipation—patients should follow the specific instructions provided by their healthcare professional.

The pregnancy safety category for magnesium hydroxide is listed as unknown. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss the use of Magnesia with their obstetrician or healthcare provider to weigh potential benefits against any possible risks.

To request Magnesia, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies, and procurement teams across international markets. After submission, the sales team will verify trade or institutional credentials and respond with pricing, availability, shipping details, and any required import documentation.

Magnesium hydroxide differs from aluminum‑based antacids by providing a laxative effect in addition to acid neutralization. Compared with calcium carbonate, it is less likely to cause constipation but may lead to diarrhea. Its rapid neutralizing action makes it suitable for short‑term relief, while the choice of antacid often depends on the patient’s gastrointestinal tolerance and comorbidities.

Magnesia should be stored at temperatures below 25 °C in its original packaging. Protect the product from moisture and direct sunlight to maintain stability. Keeping the container tightly closed helps prevent clumping and preserves potency throughout its shelf life.

Magnesia is taken orally, typically as a liquid suspension or chewable tablet, according to the prescriber’s directions. It should be measured with a calibrated device if in liquid form and taken with a glass of water. Do not crush or dissolve tablets unless specifically instructed.

Serious risks include hypermagnesemia, especially in patients with renal insufficiency, which can cause muscle weakness, low blood pressure, and cardiac arrhythmias. Allergic reactions such as rash, swelling, or breathing difficulty also require immediate medical attention. Persistent abdominal pain or vomiting may signal an underlying condition that needs evaluation.

Magnesia should be avoided in individuals with known hypersensitivity to magnesium hydroxide, severe renal impairment, or those who are taking medications that may interact dangerously, such as certain antibiotics or digoxin, without medical supervision. Children under the recommended age, unless directed by a pediatrician, should also not use the product.
