Oral antacids are occasionally prescribed for infantile colic, gastroesophageal reflux, esophagitis, and other peptic disorders.1 It has long been known that prolonged treatment with nonabsorbable antacids such as aluminum-magnesium hydroxides can limit gastrointestinal absorption of phosphorus.2 Hypophosphatemic bone disease, either rickets or osteomalacia, is a well-known complication of impaired renal tubular resorption of phosphate,3 but is rarely caused by nutritional phosphate deprivation. Although antacid-induced hypophosphatemic osteomalacia has been extensively reported in adults,4-9 very few reports exist in the pediatric literature.10,11 We report a case of rickets and secondary craniosynostosis in an infant following long-term administration of an aluminum-containing antacid.
