How often should I change my pad/tampon?
Sanitary napkins (pads) should be changed as often as necessary, before the pad is soaked with menstrual flow. Each woman decides for herself what is comfortable. Tampons should be changed often (at least every 4-8 hours). Make sure that you use the lowest absorbency of tampon needed for your flow. For example, do not use super absorbency on the lightest day of your period. This can put you at risk for toxic shock syndrome (TSS). TSS is a rare but potentially deadly disease. Women under 30, especially teenagers, are at a higher risk for TSS. Using any kind of tampon - cotton or rayon of any absorbency - puts a woman at greater risk for TSS than using menstrual pads.
