Toxicity

Intamuscular LD50 of 250mg/kg and oral LD50 of 8290 mg/kg reported in rats . Phosphate toxicity is likely due to the disturbance of other electrolytes when phosphate levels are high, producing symptoms including tetany, dehydration, hypotension, tachycardia, hyperpyrexia, cardiac arrest and coma . Risk of raising phosphate levels through use of sodium phosphate appears to be higher in smaller patients .

Food Interaction

Elimination Route
