# SUPPLEMENTARY INFORMATION:

                    In the                     **Federal Register**                     of January 4, 2001 (66 FR 801), FDA published a notice announcing the availability of a draft guidance document entitled “Potassium Iodide as a Thyroid Blocking Agent in Radiation Emergencies.” This draft guidance updates the notice of availability entitled “Potassium Iodide as a Thyroid-Blocking Agent In a Radiation Emergency: Final Recommendations On Use,” published in the                     **Federal Register**                     of June 29, 1982 (47 FR 28158). In this draft guidance, FDA maintains its position that potassium iodide is a safe and effective means by which to prevent radioiodine uptake by the thyroid gland, under certain specified conditions of use, and thus to lessen the risk of thyroid cancer in the event of a radiation emergency.                 

FDA received an e-mail request, dated January 4, 2001, requesting that the agency extend the comment period on the draft guidance by 60 days, allowing 90 days for comments. Because the draft guidance introduces several new recommendations, the agency has decided to extend the comment period on the draft guidance to April 30, 2001, to allow the public more time to review and comment on its contents. 

Interested persons may submit to the Dockets Management Branch (address above) written comments on the draft guidance document by April 30, 2001. Two copies of any comments are to be submitted, except that individuals may submit one copy. Comments should be identified with the docket number found in brackets in the heading of this document. The draft guidance document and received comments may be seen in the Dockets Management Branch between 9 a.m. and 4 p.m., Monday through Friday. 

Dated: February 2, 2001. 

Ann M. Witt, 

Acting Associate Commissioner for Policy.
