Can I leave a tampon in overnight? Like all tampons in Australia, our U by Kotex tampons can be used for up to 8 hours, but not any longer. So, while it IS possible to wear a tampon overnight, we know that everyone has different absorbency needs, as well as different sleep patterns (letâs face it, we all like a sleep in sometimes!).
The best way to know if your tampon needs changing is to give a light tug on the tampon string, if it starts to pull out easily then it's time to change, if not, it usually means you can leave it a bit longer. Just remember with tampons, 4 hours is about right, and don't leave one in for more than 8 hours.
