A: How long you can wear a tampon depends on the strength of your menstrual flow. During the first, heavier days of your period, you will probably need to change the Beppy tampon after 2 to 6 hours. During the lighter days, the tampon can be used for approximately 6 to 8 hours. Always remember to remove the last tampon at the end of your period. After a while you will begin to get a feel for how often you need to remove the tampon.
