When the first symptoms of phosphorus depletion appear in the body the preparation should be canceled immediately. Stomalox should be used with special caution in appendicitis, weakening or reinforcement effects of the preparation may trigger perforation. Aluminum hydroxide is capable of forming insoluble complexes with phosphates, which are excreted with excrement. This can lead to a reduction in phosphorus concentration in plasma and its subsequent mobilization from the bones. In patients with bones diseases the use of aluminum-containing antacids background depleted inventory levels of phosphorus in the body (e.g malabsorption syndrome) can lead to osteoporosis development and an increased risk of fractures. In elderly patients with metabolic bone diseases prolonged use of aluminum-containing antacids can lead to the depletion of phosphorus inventory levels, hypercalciuria and delayed absorption of fluoride from the intestine.

Paediatric use

Stomalox should be applied to the children under 12 years only in those cases when the preparation is prescribed by a doctor.
