Do tampons expire?

Last time i bought tampons was in October of 2018 then i got pregnant so it’s October again and i still have the same box of tampons. I was wondering if it was safe to use them? I used a few from the box last year and they’ve been in a suit case since then because i never unpacked them when we moved. Should i just throw them away and buy more?
