How long it takes to excrete sodium phosphate in the body requires a specific analysis of sodium phosphate toxicity, the amount ingested and the basal metabolic rate of the patient’s body. In mild cases of sodium phosphate poisoning, the body is relatively good or the basal metabolic rate is relatively high, a small amount of sodium phosphate intake can be completely metabolized within 24-48 hours. If the sodium phosphate poisoning components are more or ingested through the esophagus, through the respiratory tract inhalation, a variety of channels are absorbed by the body after excretion is relatively difficult, it takes about 3-5 days to metabolize clean. If the patient’s underlying immunity is poor or weak, or if the sodium phosphate salt has been ingested for a longer period of time and there has been multiple organ failure, for example, liver and kidney function has been impaired, it will take at least 7-10 days to be completely excreted.
