The correct dosage
The correct dosage of iodine tablets for iodine blockade is dependent on a person’s age. It is therefore important that you follow these instructions closely, as you may put your own and your child’s health at risk by administering a dosage that is too high or too low.
Up to 1 month
Babies aged one month or less should be given a dosage of 16.25 milligram (mg) of potassium iodide, once the emergency response authorities have given instructions to proceed. This is the equivalent of a quarter of a tablet.
From 1 month to 3 years
Infants and toddlers aged between one month and three years should take a dosage of 32.5 milligram (mg) potassium iodide. This is the equivalent of half a tablet.
From 3 to 12 years
Children aged between three and twelve years should take 65 mg potassium iodide. This is the equivalent of one iodine tablet.
From 12 to 45 years
Those aged between 12 and 45 should take two iodine tablets or 130 mg potassium iodide to protect themselves against radioactive iodine.
Pregnant women and breastfeeding mothers
Women who are pregnant or who breastfeed should take two iodine tablets with a total dosage of 130 mg potassium iodide, regardless of their age. Pregnant women are also advised to inform their GPs about the intake of iodine tablets. This will ensure that the newborn’s thyroid screening will be paid special attention.
Over 45 years
Adults aged 45 or older should not take any iodine tablets. The risk of metabolism dysfunctions in thyroids increases with age. This so called functional autonomy increases the risk of the iodine tablets’ side effects. As people get older the risk of developing thyroid cancer caused by ionizing radiation decreases considerably.
