    3OVERDOSAGE
    Alendronate Sodium
    Significant lethality after single oral doses with alendronate was seen in female rats and mice at 552 mg/kg (3256 mg/m
    No specific information is available on the treatment of overdosage with alendronate. Hypocalcemia, hypophosphatemia, and upper gastrointestinal adverse events, such as upset stomach, heartburn, esophagitis, gastritis, or ulcer, may result from oral overdosage. Milk or antacids should be given to bind alendronate. Due to the risk of esophageal irritation, vomiting should not be induced and the patient should remain fully upright.
    Dialysis would not be beneficial.
    Cholecalciferol
    Significant lethality occurred in mice treated with a single high oral dose of calcitriol (4 mg/kg), the hormonal metabolite of cholecalciferol.
    There is limited information regarding doses of cholecalciferol associated with acute toxicity, although intermittent (yearly or twice yearly) single doses of ergocalciferol (vitamin D
    Dialysis to remove vitamin D would not be beneficial.
