It's complicated : As per dr rhoads please contact your poisons centre or an emergency doctor licensed in the us. The iodine can have prolonged effects on the thyroid gland and so needs specific consultation urgently to get advice for your situation.

It's complicated!: The plasma half-life of a single dose of iodine is fairly short (6-24 hours) but only a fraction of iodine is immediately excreted in urine. The majority is taken up by the thyroid gland and used to synthesize thyroid hormones. The half-life of circulating thyroid hormones is 1-8 days. You can't "untake" a high dose of Iodine but, for future reference, don't take any more than 600 mcg/day.
