How to stop header showing up in nomenclature page?

I am trying to make a nomenclature table but the header seems to keep showing up at the top of the page?

tableofcontents

addtocontents{toc}{protectthispagestyle{empty}}
cleardoublepage           
renewcommand{nomname}{List of Symbols} %% may be this is good.
markboth{MakeUppercasenomname}{MakeUppercasenomname} 
thispagestyle{empty}
nomenclature{$a$}{action}

printnomenclature
