Gemstain Overdosage

Symptoms of acute poisoning from ingestion of iodine include a disagreeable metallic taste, vomiting, abdominal pain and diarrhea may occur. Renal failure may occur 1-3 days later. Death may be caused by circulatory failure, swelling of the epiglottis causing asphyxia, aspiration, pneumonia or pulmonary oedema. Oesophageal stricture may occur if the patient survives the acute stage. The fatal dose of iodine is 2 to 3 g.
Symptomatic treatment for allergic reactions and iodism may be required, although symptoms usually subside rapidly when administration of iodine or iodide is stopped. In acute poisoning copious draughts of milk and starch mucilage should be given. If there is no oesophageal damage the stomach may be emptied by aspiration and lavage with dilute starch mucilage or a 1% solution of sodium thiosulphate. Use of gastric lavage with activated charcoal has also been suggested. Electrolyte and water losses should be replaced and the circulation should be maintained. Pethidine or morphine sulphate may be given for pain, under medical supervision. A tracheotomy may become necessary.
