Overdosage
Chewable tab: Signs and Symptoms: Reported symptoms of acute overdose with aluminum hydroxide and magnesium salts combination include diarrhea, abdominal pain, vomiting.
Large doses of this product may trigger or aggravate intestinal obstruction and ileus in patients at risk (see Warnings).

Warnings
Chewable tab: Aluminum hydroxide may cause constipation and magensium salts overdose may cause hypomotility of the bowel; large doses of this product may trigger or aggravate intestinal obstruction and ileus in patients at higher risk such as those with renal impairment, infants less than 2 years, or the elderly.
Aluminum hydroxide is not well absorbed from the gastrointestinal tract, and systemic effects are therefore rare in patients with normal renal function. However, excessive doses or long-term use, or even normal doses in patients with low-phosphorus diets or in infants less than 2 years, may lead to phosphate depletion (due to aluminum-phosphate binding) accompanied by increased bone resorption and hypercalciuria with the risk of osteomalacia. Medical advice is recommended in case of long-term use or in patients at risk of phosphate depletion.
In patients with renal impairment, plasma levels of both aluminum and magnesium increase. In these patients, a long-term exposure to high doses of aluminum and magnesium salts may lead to encephalopathy, dementia, microcytic anemia, or worsen dialysis-induced osteomalacia.
Aluminum hydroxide may be unsafe in patients with porphyria undergoing hemodialysis.
Oral susp: Do not take more than 16 teaspoonful (80 mL) in a 24-hour period or use the maximum dosage for more than two weeks. Do not use if you have kidney disease except under the advise and supervision of a physician.

Special Precautions
Chewable tab: The prolonged use of antacids in patients with renal failure should be avoided.
Care should be observed if used by diabetics because of the sugar content in the tablet.
Oral susp: Aluminum hydroxide may cause constipation due to its astringent action, this effect may be balanced by the cathartic effect of the magnesium salts.
Aluminum hydroxide may lead to a phosphate depletion syndrome, particularly in patients on a low phosphate diet eg, malnutrition.
Magnesium salts may cause central nervous depression in the presence of renal insufficiency and should be used with caution in patients with advance renal disease.
In patients with renal impairment, plasma levels of both aluminum and magnesium increase. In these patients, a long-term exposure to high doses of aluminum and magnesium salts may lead to encephalopathy or worsen dialysis osteomalacia.
The prolonged use of antacids in patients with renal failure should be avoided.
Effects on the Ability to Drive or Operate Machinery: None.
Use in pregnancy: Maalox should not be used during pregnancy unless considered essential by the physician.

Action
Oral susp: Pharmacology: ATC code: A02A B10 (Antacids: Aluminum compounds; combination).
Pharmacodynamics: Maalox is a balanced mixture of 2 antacids: Aluminum hydroxide is a slow-acting antacid and magnesium hydroxide is fast acting. The 2 are frequently combined in antacid mixtures. Aluminum hydroxide on its own is astringent and may cause constipation. This effect is balanced by the effect of magnesium hydroxide, which, in common with other magnesium salts, may cause diarrhea.
Pharmacokinetics: The absorption of aluminium and magnesium from antacids is small. Aluminum hydroxide is slowly converted to aluminium chloride in the stomach. Some absorption of soluble aluminium salts occur in the gastrointestinal tract with urinary excretion. Any absorbed magnesium is likewise excreted in the urine.
Toxicology: Preclinical Safety Data: Not relevant.
