I'm not sure to understand pefectly what you are doing with your glossary and macro, but it is easy to just make a header/footer on the first page different from the following pages.
Select the menu View, and then the option Headers and Footers
On the toolbar that appears, click on Page Setup (browse the icons it to locate it reading the tooltips)
On the dialog Page Setup, you will find 3 tabs. Select the Layout tab, and then the option Different first page
And you are done!
In this document, anything placed on the header or footer of the first page will not appear in any of the following pages.
