Can I Wear a Tampon Overnight?
Question: Can I wear a tampon overnight?
Dr. Farah Kroman: The general rule for wearing tampons is to change every 3-4 hours; earlier if it fills up; or after a maximum of 8 hours. Sleeping with a tampon is not a problem so long as you change it at around 8 hours. Make sure you pop it in just before you go to sleep and change it as soon as you wake up.
