Potassium Iodide (KI)

The Ohio Department of Health (ODH) participates in a program sponsored by the United States Nuclear Regulatory Commission (NRC) to supply Potassium Iodide (KI) pills to the general public within the 10-mile Emergency Planning Zone (EPZ) around each commercial nuclear power plant.  The following counties are in the 10-mile EPZ:  Ashtabula, Columbiana, Geauga, Lake, Lucas, and Ottawa.

KI Lots TU401A and TU404A’s expiration dates have been extended to June 30, 2022.  Original expiration dates are listed below. These lots have been tested in accordance with FDA shelf-life extension guidelines, and the expiration date has been extended to accommodate a small number of tablets that could not be switched out by Dec. 31, 2021, amid the COVID-19 pandemic.

New replacement KI from the NRC arrived in 2020.  The new replacement KI has been distributed to the local and county health departments within the 10-mile EPZ.  Members of the public in the 10-mile EPZ should contact their local or county health department for information about the availability of KI.  During an incident, KI will be made available at evacuation reception/care centers. This new lot of KI (TU903A) has an expiration date of Oct. 31, 2029.  

The Ohio Environmental Protection Agency recommends disposing of expired KI by placing in the household trash.  The following table lists the expired lot numbers and extended expiration dates.
