A small intake of iodophor for disinfection may not be dangerous, but an excessive intake can be dangerous. Because iodophor is mainly used for local disinfection and the dosage is relatively small, if too much iodine is accidentally ingested, it can stimulate the local mucosa and cause an inflammatory reaction, local congestion, edema or even poisoning, gastrointestinal symptoms, nausea, vomiting or discomfort in the upper abdomen. Very few patients are allergic to iodine and may develop anaphylactic shock, which is more dangerous at this time and requires anti-allergy and anti-shock treatment. Those who have ingested too much need to be taken to hospital in time and cannot be handled by individuals.
