When using tampons, it’s important to choose the lowest absorbency necessary for your menstrual flow. And because the amount of flow varies from day to day, it’s likely that you will need to use different absorbencies on different days of your period. Selecting the right absorbency comes with experience but, as a guide, if a tampon absorbs as much as it can and has to be changed before four hours, then you may want to try a higher absorbency. On the other hand, if you remove a tampon and after 4 - 8 hours white fiber is still showing, you should choose a lower absorbency.
A tampon can be worn for a maximum of 8 hours. When using a tampon at night, choose the lowest absorbency needed, insert a fresh one just before going to bed and remove it as soon as you wake up in the morning. If you plan to sleep for more than eight hours, a pad should be worn instead.
The risk of tampon-related TSS may also be reduced by using pads as an alternative from time to time during a period.
