An iodine overdose can happen easily if you misread the directions for iodine supplementation. Iodine poisoning may happen after an extended period of time using an incorrect dosage.
Topically, an iodine reaction may occur with the use of iodinated povidone. Tincture of Iodine may cause rash, blistering or crusting on the skin.
Iodine poisoning may happen if you have been exposed to high doses of radiographic contact dyes or a drug called amiodarone.
Sometimes gastrointestinal obstructions treated with sodium iodide may cause strong reactions.
Bladder irrigation with Povidone iodine has been known to increase the risk of urinary tract infection which may lead to kidney failure or death.
Initial symptoms of iodine toxicity may be:
If the overdose continues it can lead to:
A type of acne called kelp acne was found in individuals who ingested high amounts of kelp in Japan.
Consumption of this seaweed, which contains a high amount of iodine, is common for this culture.
If you experience acne and consume a high amount of kelp, simply cutting back on your consumption of kelp should solve the problem.
According to MedHelp, you may ingest milk, or water mixed with either cornstarch or flour every 15 minutes.
If there is vomiting, convulsions, or lethargy making it hard for the individual to swallow, stop the treatment.
Contrary to popular belief, the consumption of chocolate to absorb excess iodine does not work.
It is purported that it contains bromine. Bromine, a known disruptor or halogen, disrupts or blocks the absorption of iodine.
Upon closer examination and according to Wikipedia, the compound in chocolate, theobromine, does not contain bromine.
Therefore, unfortunately, the use of chocolate to reduce an iodine overdose is ineffective.
However, you may consume a bread product containing "enriched" or bromated flour.
By consuming bread products which contain bromated flour, the excess iodine is absorbed.
Thirty years ago, iodine was used in all bread products to prevent iodine deficiency. It was decreed by a higher governmental authority, that iodine should be removed from bakery products.
Now, we're slowly being overdosed with bromine from the bread and baked products we eat.
