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!).
Answer   You do NOT need to take out your tampon when you swim or go to the restroom. Doctors advise you not to wear them to bed because of the length of time you are aslâ¦eep. I hope that helped!!   If you sleep for more than 8 hours you should wear a pad instead. Otherwise it is ok to wear a tampon.
