To Individuals Residing in the Emergency Planning Zone (EPZ):
The State of New Hampshire is providing potassium iodide (KI) tablets to residents within the Emergency Planning Zone (EPZ) as a precautionary measure in the event of a radiological emergency. Please read the following disclaimer carefully before accepting and using the potassium iodide tablets.
Purpose of KI Distribution:The distribution of potassium iodide (KI) is intended as an additional protective measure to reduce the risk of thyroid cancer and other thyroid-related issues that may result from exposure to radioactive iodine. KI is to be used in conjunction with other emergency measures such as evacuation or sheltering in place.
Usage Instructions:It is essential to follow the dosage and administration guidelines provided by public health officials and included with the KI tablets. Taking KI without proper guidance can lead to serious health risks.
Recommended Dosing of KI:
Adults (including pregnant and breastfeeding women): 130 mg 2 TabletsAdolescents (12-18 years) who weigh at least 70 kg (154 lbs): 130 mg 2 TabletsAdolescents (12-18 years) who weigh less than 70 kg (154 lbs): 65 mg 1 TabletChildren (3-12 years): 65 mg 1 TabletInfants (1 month – 3 years): 32 mg 1/2 TabletNewborns (birth – 1 month): 16 mg see consumer package insert NO MORE THAN ONE DOSE FOR INFANTS
Additional Notes:
Timing: KI should be taken as soon as possible after public health officials advise that it is needed. The effectiveness is highest if taken shortly before or immediately after exposure to radioactive iodine.
Frequency: A single dose of KI provides protection for 24 hours. Further doses may be necessary if there is ongoing exposure, as advised by public health officials.
Effectiveness:Potassium iodide (KI) is effective only in preventing the absorption of radioactive iodine by the thyroid gland. It does not provide protection against other types of radiation or radioactive materials.
Potential Side Effects:While generally safe for most people, potassium iodide (KI) can cause side effects in some individuals, including allergic reactions, gastrointestinal disturbances, or thyroid dysfunction. Those with known allergies to iodine, or who have certain medical conditions (e.g., thyroid disease, dermatitis herpetiformis, or hypocomplementemic vasculitis) should consult a healthcare provider before using KI.
Not a Substitute for Evacuation:Receiving and taking potassium iodide (KI) does not replace the need to follow other emergency instructions from state and local authorities, including evacuation orders. Evacuation and sheltering in place remain the primary protective actions in a radiological emergency.
No Guarantee of Safety:While potassium iodide (KI) can reduce the risk of thyroid cancer due to radioactive iodine exposure, it does not guarantee complete safety. Residents must adhere to all other recommended safety measures.
Personal Responsibility for Replacement:Individuals are responsible for monitoring the expiration date of their potassium iodide (KI) tablets and replacing them when they expire. The State of New Hampshire will not provide automatic replacements. Expired tablets should not be used, as their effectiveness cannot be guaranteed.
Personal Responsibility:By accepting the potassium iodide (KI) tablets, individuals acknowledge and agree that the State of New Hampshire, its agencies, and employees are not liable for any adverse effects or incidents arising from the use or misuse of KI.
