Do not use maximum daily dose for more than 2 weeks.

Precautions

The most common adverse effect associated with aluminum antacids is constipation.

Magnesium containing antacids commonly cause a laxative effect.

Patients with renal failure may accumulate aluminum with chronic use. Serum aluminum levels should be monitored or another antacid chosen.

Elevated tissue aluminum levels contribute to the development of the dialysis encephalopathy and osteomalacia syndromes.

Do not use drug before consulting with a doctor if you have kidney disease.

Aluminum forms insoluble complexes with phosphate in the gastrointestinal tract, thus decreasing phosphate absorption which can lead to hypophosphatemia. In patients on hemodialysis who are maintained on aluminum antacids, serum phosphate concentrations should be monitored at monthly or bimonthly intervals.
