Aluminum Hydroxide: UC Uses, Warnings, Side Effects, Dosage

Generic Name: aluminum hydroxide

Brand Names: AlternaGEL, Amphojel, Nephrox

Drug Class: Antacids

What is aluminum hydroxide, and what is it used for?

Aluminum hydroxide is an antacid available over the counter and is used to relieve heartburn from gastrointestinal acidity associated with gastritis, peptic ulcers, ulcerative colitis, and gastroesophageal reflux disease (GERD).

Aluminum hydroxide is also used off-label to treat excessive phosphate levels in the blood (hyperphosphatemia) associated with chronic kidney disease.

Aluminum hydroxide works by neutralizing hydrochloric acid, the acid produced in the stomach, but it has no effect on acid production itself. Aluminum hydroxide reacts with hydrochloric acid producing water and aluminum chloride, which is excreted in the stools.

By neutralizing stomach acid, aluminum hydroxide raises the pH level in the stomach, making it more alkaline, which inhibits the production and activity of pepsin, a stomach enzyme that breaks down dietary proteins and damages the stomach lining in peptic ulcer disease.

Reduction in the acidity of the stomach and reduced pepsin activity help heal peptic ulcers and also reduce acid reflux in the esophagus. Aluminum hydroxide also binds to phosphates in the gastrointestinal tract and forms insoluble complexes that are eliminated in the feces. This prevents the absorption of dietary phosphate and helps reduce phosphate levels in the blood.

Warnings

  • Do not take aluminum hydroxide if you are hypersensitive to aluminum salts.
  • Use with caution in patients with heart failure, cirrhosis, kidney disease or edema, who need to be on a sodium-restricted diet.
  • Use with caution in patients who have had a recent gastrointestinal hemorrhage.
  • Use with caution in patients with colostomy, diverticulitis, or ileostomy, because aluminum hydroxide increases the risk of electrolyte imbalance.
  • The risk of constipation and fecal impaction with aluminum hydroxide is higher in elderly patients.
  • Avoid long-term use of aluminum hydroxide in patients with chronic kidney disease stages 3 to 5, it may cause aluminum toxicity and related bone softening (osteomalacia) and brain damage (encephalopathy).
  • Systemic absorption of aluminum has been reported both with short and long-term antacid therapy in infants. Use with caution and monitor for adverse effects.
  • Over-the-counter use of aluminum hydroxide is not recommended as an antacid in infants younger than 2 years of age without supervision of a physician.
  • Prolonged use of aluminum hydroxide may lead to excessively low phosphate levels in blood (hypophosphatemia).
  • Use with caution in patients with chronic diarrhea, there is a higher risk for hypophosphatemia.
