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!).
You may have HMB if you: 1  Wear both a tampon and a pad for double protection. 2  Soak through a pad or tampon every 2 to 3 hours. 3  Have ever stained your clothes as a result of a heavy period.  Have to get up in the middle of the night to change your pad or 1  tampon. Sleep with a towel for extra protection.
