Tampons should be changed every 4-6 hours - some tampon companies  say 8 hours to make their products seem more convenient, but that's  too long to wear a tampon and if you â¦can go that long without  leaking you're using too high an absorbency.
But if your period is so heavy that you have to change your pad or tampon more than once an hour, or if the menstrual blood is coming out in a steady stream that won't stop, or if your period lasts longer than seven days, you need to go to your doctor.
