So, How Long Can You Leave A Tampon In? You should only keep a tampon in for up to 8 hours. So if you’re about to hit the sheets and are planning to sleep with a tampon in, first be sure to put in a new one, and then remove it as soon as you’re done with your beauty sleep. If you’re totally exhausted and think you’ll sleep longer than that, you should wear a pad instead.
