"When are Iodine dressings contraindicated?
Iodine dressings must be used under medical supervision in patients with thyroid diseases, known or suspected Iodine sensitivity, in pregnant or breastfeeding women or in newborn babies and up to the age of six months8.
Long-term use of PVP-I has been loosely associated with mild hyperthyroidism[29] and long-term use is not recommended for patients with impaired thyroid function. However, a number of studies have monitored thyroid function during PVP-I clinical trials and have reported that it remains unchanged[30-32]. "
I wish that I could take enough Iodine to go slightly hyperthyroid. I would do it in a second.
